This is a GO train.

It's part of Ontario's commuter rail network with seven lines that connect Toronto and the cities around it.

And Metrolinks, which is the provincial agency that owns GO, is running a project called GO Expansion with a price tag of roughly $27 billion.

I do like to start any of these sessions by just reminding us collectively of what it is we're actually doing, yeah?

So we are building the largest expansion and modernization of a commuter rail network anywhere in the world.

Anywhere in the world.

We are building out.

Deserve it.

And the idea behind the biggest expansion and modernization of a commuter rail network in the world is quite simple.

You stop looking at schedules.

You just walk up to the platform and an electric train shows up within 15 minutes.

Originally, this was supposed to be done by 2032, but it has now quietly shifted to 2042.

So, the reason for that 10 -year delay?

Well, there isn't one.

There are a lot of them.

So, to explain each problem with this project in simple terms, I made a transit game that we are going to play together.

And our starting point is going to be right here at Aldershot Station.

so let's play first we gotta give our passenger a name let's call him andy

and andy is currently sitting at aldershot

and instead of a friday maybe let's pick monday at 8 a .m in the morning

and let's click start all right so in this game every single train

that you see on the line is moving according to a real go schedule

so for example this one

this one is currently going to malton station at the speed of 64 kilometers an hour as

if though it was actually monday at 8 a .m in the morning

so according to a real go schedule this is where

that train would be but again this is a game

and i don't want to wait for trains to move for

so long so i can just simply increase this speed

and that's how we can make those trains move faster

but for the purposes of today's video we're going to follow a specific path, but if you want to explore this simulator for yourself,

I attached the link down in the description.

Anyways, Andy is at Aldershot, and Andy wants to get to Burlington.

So let's click on Burlington, and we can see that the next train departs in about five minutes.

But of course, we're not going to just sit and wait here for five minutes, so let me just increase the speed.

And while we're waiting for that train to arrive, I should mention that this is Lakeshore West line, one of seven go lines.

It goes all the way from downtown Toronto, so from Union Station, all the way to Niagara Falls.

But we won't be going that far out today.

Let me zoom back in and we can see that Andy's train is over here.

We can now board it.

So it's a suggested train.

It's going to Union, but we just need to go essentially one stop.

So what we can do is simply click on board train.

Doors are now closed and Andy is on his happy way to Burlington station.

As you can see I'm Andy and I'm headed to Burlington.

Your next stop Burlington, go.

But what I wanted to say is that Lakeshore West,

it's one of seven go lines and it's the busiest one so naturally it gets priority under go expansion.

As of today during rush hour you get a train from here all the way to Union roughly every 15 minutes, which is great.

So railways call that on peak mornings and evenings, but everything else is off peak, for example middays or weekends.

And during those times you need to wait for your next train at least twice as long.

And that is the whole point of GO expansion.

15 minutes should mean 15 minutes, whether it's Monday morning or Saturday afternoon.

So how is Mitterlings going to get to a higher frequency of trains?

Well, to answer that, you need to know what's actually pulling the train that Andy is currently on.

The newest locomotive that GO has is called MP54AC, built by Motive Power in Boise, Idaho.

It has two diesel engines producing 5 ,400 horsepower, making it the most powerful diesel passenger locomotive in north america

and it needs every bit of that

because it needs to be able to pull up to 12 double -decker coaches each weighing at least 50 tons

and then it needs to generate electricity heating and air conditioning to ensure that everybody on board is happy

so it looks like it's one locomotive doing all of the work

while those coaches are simply there along for the ride but the thing is

That locomotive can absolutely pull all of those coaches without any problems.

What it cannot really do is get those coaches moving from zero very quickly.

And that matters, because if a train takes a long time to clear a station, the next one has to wait further back.

Slow acceleration doesn't just mean that your trip is longer, it also dictates how many trains each line can hold.

And it looks like Andy is currently arriving at Burlington Station, so let's check in with him.

There is a solution to not -so -fast acceleration, though, in the form of electric trains.

Instead of having one locomotive doing all the pulling,

electric trains spread their engines under multiple different cars so that as many wheels as possible actually pull.

And in my opinion, one of the obvious candidates to replace GOES diesel locomotive fleet is the Stadler Kiss.

It's a Swiss double -decker electric train that runs all over Europe and even in North America, specifically on Caltrain in California.

But in order to meet Canadian regulations, Metrolinks needs a custom electric train.

So the thinking, at least as of today, would be to build a plant, probably somewhere in Ontario, where those trains would be made,

and then convince other transit agencies to get them, so that the production line would make some sort of financial sense.

But which manufacturer would be willing to do that?

Well, this is pure speculation on my part, but most likely Metrolinks is going to go with Alstom.

They're French, but they bought Bombardier's rail division back in 2021,

and they're also the ones who are running GoTrain's as of today as part of a $1 .3 billion contract

that expires in 2031.

But again, no electric trains have been ordered, but according to Metrolinks, the very first one should be launched around year 2036.

Now, the thing is, even if you do manage to get electric trains, they need electricity from overhead wires.

And the reason why Andy is currently sitting at Burlington Station in the first place is

because according to this GO expansion plan, Burlington will be the very last electrification point along this Lakeshore West line.

So anything west of that won't be electrified.

We'll talk more about overhead wires in a moment, but now I need to send Andy to his next stop, which is going to be Union.

So let's click on Union, and it's going to be quite a journey at 61 minutes.

Actually, before we talk more about the overhead wires, there's something else.

Again, even if Goat does figure out where to get their electric trains from, they will naturally run faster and closer to each other.

So keeping them safely apart is also something that needs to be figured out.

Today a GO train stops only because the operator, they look ahead and they see a red light.

And the system knows where that train is because its wheels complete an electrical circuit, which is a very, very old technology.

That's why Metrolinks is installing a system called ETCS Level 2, which stands for European Train Control System,

where a signal appears inside of the operator's cab.

And Metrolinks has already started experimenting with it.

Because as of June of 2026,

the very first GO cab has been fitted with ETCS and a test track is being built along Richmond Hill line.

This will be the very first deployment of ETCS anywhere in North America.

But this is where we get into a bit of a pickle.

100

To understand that pickle, let's first board Andy onto his union -bound train.

101

It's almost here.

102

Let me just increase the speed and board train.

103

Perfect.

104

So the thing is, the very first draft of Go Expansion Project was published in 2008, when Metrolinks released their paper called The Big Move.

105

It was this 25 -year plan for how this entire region would move

106

and its very first priority was a fast expanded

107

and frequent regional rail network a few years later it even got a name it was called r er

108

or regional express rail

109

but at first of course politicians had to figure out who would actually pay for all of this

110

so not a lot of physical work was actually done

111

but by 2013 metrolinks had already started upgrading the USRC or the Union Station Rail Corridor.

112

Even back then, 13 years ago, it was clear that if Go wanted to run more trains,

113

the biggest choke point in this entire plan would be Union Station, because that's exactly where every single line converges.

114

And it looks like Andy is currently arriving at Union Station, so let's see exactly what I'm talking about.

115

Yeah, Union Station is absolutely massive, and Go is by far its biggest user.

116

Somebody has to control where all of these trains are going, right? it.

117

So who does it?

118

Well, for the better part of a century, it's been done from a few brick towers, including this one.

119

It's called the John Street Interlocking Tower.

120

It's a very old technology with wires, relays, and switches.

121

But the manager of it called it the Elon Musk of the 1920s because in theory, it could run for another hundreds of years.

122

But that system has a bit of a throughput problem.

123

It can manage trains maybe every 30 minutes,

124

but basically it cannot continuously juggle trains on each line all day in both directions every 15 minutes.

125

So back in 2013, Metrolinks started the process of replacing the signals inside the Union Station rail corridor,

126

but that work started before the final plans for GO expansion were locked in.

127

And that turned out to be a very big problem.

128

Because before anyone even knew what the final project would look like,

129

engineers started replacing the signals inside the USRC based on the track layout that

130

Union already had.

131

And that work went on for 10 years.

132

And then in 2023, Metrolinx realized that the work that they'd been doing for the past decade was now essentially obsolete.

133

The upgrades that they did were now useless because they were based around the track layout that would eventually have to change.

134

So in June of 2026, Metrolinx announced that they were writing off more than half a billion dollars of taxpayers' money.

135

They did say that a usable portion was retained.

136

Now, what portion exactly?

137

Well, that we don't know for sure, but I'm standing here above the rail corridor at Blue Jaysway,

138

and take a look at these signals over there.

139

They are either covered or turned to their side.

140

Their wires are not even connected to anything, so clearly they're out of service.

141

And also take a look at this.

142

I found the manufacturer's label on one of those signal bridges.

143

They were made in Winnipeg back in December of 2014, about one month after the contract was signed.

144

And the signals themselves are stamped with General Electric logo, which makes sense because the company that won this contract,

145

Alstom, well, they bought GE's rail signaling business back in 2015.

146

So you could argue that these signals will get turned on at some point for freight trains

147

that wouldn't have this fancy European train control system on board.

148

But they'll be pointing at the wrong tracks down below maybe they will get adjusted maybe not

149

but at this point again this is just pure speculation on my part

150

this is probably at least a part of where half a billion dollars went

151

now we'll come back to union station in a second

152

because it's time to send andy over to lakeshore east line specifically to oshawa station

153

and our train is already here it's going to leave in about four minutes

154

but the thing is lakeshore east also gets quite busy

155

and it's going to be both electrified

156

and actually it's going to be expanded as well

157

so together with lakeshore west it's the only full corridor slated for electrification in the near term

158

so let me see the train is going to leave in

159

about three minutes let's click board train let me speed

160

this up the doors are now going to close much quicker

161

and it looks like now let me zoom in andy is on his way to Oshawa.

162

Right now Oshawa is the very end of the Lakeshore East line

163

but not for long because it's getting an 18 .7 kilometer extension in the form of four new stations.

164

They're going to be called Thornton's Corners East, Ritson Road, Cordes and Bowmanville.

165

And Metrolinks contracted that work out to Bowmanville construction partners which are Leadcor and Dragados Canada.

166

The contract is worth about $1 .5 billion and it's going to take about 15 years to complete.

167

So we're talking early 2040s, though they officially broke ground in January of 2026.

168

But here's what's interesting.

169

Those four stations, they're not a part of that contract

170

because Metrolinks wants private developers to pay for them through their transit -oriented communities program

171

so the tracks themselves are funded but the stations not yet

172

and what about electrification well just like on lake shore west

173

the overhead wires do not cover the entire line currently the plan is to electrify from union to the existing Oshawa station.

174

But then I had a question.

175

What happens when an electric train reaches the end of the wires, but there are still four stations to go?

176

Well, it looks like Andy is currently arriving at Oshawa station.

177

So let's just ask him.

178

Well, I think nothing would happen.

179

The electric train is simply going to stop, turn around and then head back to Union Station.

180

But let's say I wanted to get from here, from Oshawa, two more stops to Ritson Road, for example.

181

I would have to get off and then wait for a diesel train to arrive.

182

Because the way that GO Expansion is designed is, well, those electric trains will be handling busy routes, in this case from Union to Oshawa,

183

and then beyond Oshawa, so to Bowmanville, diesel trains will still be running.

184

There is another option though, and it's called a battery power train.

185

They will be able to charge up underneath those overhead wires and then coast on battery power when those wires end.

186

Metrolinks looked into that technology, but according to their own words, for a train of the size that they need, it's still in its infancy.

187

But battery -powered trains, or BMEWS for short, they're not science fiction. In fact, the UK has just ordered 29 of them from Alstom to

188

run past the end of the wires in the north of England.

189

Now, those are smaller, they're also single -deck, but the thing is, they already have the factory, they have the contract and the money,

190

and they're promising to launch them in the UK by 2034.

191

Metrolinx has none of the above and they're promising 2036.

192

So I guess we'll just have to see.

193

So let's make a U -turn and send Andy back to Union Station.

194

Let me just click here.

195

Our train is already at the station, leaves in about 20 seconds.

196

Let's click board.

197

Let's increase the speed a little bit.

198

Doors are closed and Andy is on his way.

199

So, electrification is great, right?

200

It's clean, it's quiet, and the trains are faster.

201

But it needs a ton of infrastructure in the form of overhead wires, which we just discussed.

202

But remember Union Station?

203

On top of $504 million spent on signals that nobody really needs anymore, Metrolinks has another huge problem over there.

204

Those overhead wires, or catenary as railways call them, they simply do not fit under the roof of Union Station

205

because it's way too low by a matter of a few inches.

206

You might say, so what?

207

Just raise the roof, right?

208

Well, it's not so simple.

209

The thing is, Union Station is a national historic site.

210

And that label doesn't just apply to the beautiful building on Front Street.

211

It also applies to the steel roof that covers the tracks, and it was built in 1929.

212

So if Metrolinks wanted to make any changes to it, it needs to put together a proposal.

213

And then the City of Toronto, the Province of Ontario, and then

214

Parks Canada, they all need to sign off on it.

215

And it looks like Andy is currently arriving at Union Station, so let's go take a look at that roof together.

216

Well, here it is.

217

These steel arches went up almost 100 years ago to keep rain

218

and snow off of the passengers and also let the smoke out from steam locomotives.

219

Starting in 2010, though, Metrolinks spent about $248 million restoring this roof.

220

They were allowed to replace the middle section with this huge new glass atrium, but the rest, about 7 acres of steel,

221

that had to stay exactly as it was.

222

So now Metrolinks has four different options.

223

The first one is to use a metal rigid rail on the roof instead of overhead wires, just like certain railways do inside of tunnels.

224

Option number two is to dig up the tracks and then lower them, but there's a thick concrete slab underneath,

225

so that virtually sounds impossible to do.

226

Option number three is to cut every single steel column in the roof

227

and then insert a taller piece in between

228

so you can literally just jack the whole roof up

229

but there are thousands of people who walk underneath every single day

230

so that method sounds a little dangerous

231

or finally just leave union station as is

232

and use battery power trains they can drop their pantographs

233

and roll into union station on battery power those are the ones that the UK has just ordered,

234

and in fact, railways use that method all over the world.

235

It's nothing new.

236

But as of today, no decision has been made.

237

So now let's send Andy to another station, this time Kitchener.

238

Let's click on this one.

239

The next train leaves in 24 seconds.

240

Let's click board.

241

Let's speed this up.

242

And Andy should now be on his way to Kitchener.

243

While I'm on my way to Kitchener, let's talk about this line because it needs a lot of TLC.

244

Originally, it was supposed to be electrified as well, but according to the latest Metrolink's 10 -year plan, the overhead wires stop at Pearson Airport.

245

And that stretch from Union to Pearson, well...

246

Up Express uses it.

247

And also you gotta remember that anywhere within the network, the very first electric train won't show up until at least 2036.

248

And Lakeshore lines are probably going to get them first.

249

Kitchener would come way after that, we're talking late 2030s.

250

Even if then.

251

But electrification is like the last problem to worry about here, because for the most part of this journey, Go doesn't even own the tracks.

252

That's right.

253

Because between Bramley and Georgetown, Go uses Canadian National's main freight line.

254

So essentially they have to squeeze in between the freight trains.

255

And if CN needs the track, CN gets the track, if you know what I mean.

256

And then from Georgetown to Kitchener, Metrolinks does own the tracks, but they're mostly single track.

257

So a train in each direction, they have to take turns.

258

But there's progress though, because in October of 2025,

259

Ontario signed an agreement in principle with CN to buy about 21 kilometers of land from them

260

and then build tracks just for go.

261

But as of today, it's just an agreement in principle and the land hasn't exchanged any hands.

262

And it looks like Andy is currently arriving at Kitchener.

263

So let's talk about yet another huge problem.

264

The thing is, there's a whole web of companies involved in this project, but in 2025, it all just blew up.

265

The consortium hired to deliver

266

Go Expansion is called OnExpress, and it consisted of four companies.

267

ACON from Canada, FCC from Spain, Alstom from France, and Deutsche Bahn, a German National Railway.

268

And then a related company called OnExpress Operations, which was majority owned by Deutsche Bahn with AECON as their junior partner,

269

was supposed to take over running GO for the next 23 years, starting in 2025.

270

But then Deutsche Bahn, or DB for short, came in wanting to run GO the way that railways run in Europe.

271

For example, crew scheduling.

272

The Trillium, which is a news outlet, they got hold of one cruise ship description that ran for nine hours.

273

And in those nine hours, the crew spent under two actually operating a train with passengers on it.

274

The rest was just deadheading and waiting around.

275

But of course, that is unavoidable in any system.

276

But DB wanted to make it better and more efficient by using their own German software.

277

But Metrolinks didn't like that idea, and they actively discouraged its use.

278

They basically said that things just work differently in Canada.

279

And then in 2025, the handover never happened, and in May of that year, Deutsche Bahn's operating contract was fully terminated.

280

DB called it a significant realignment, while Metrolinks told its employees that they had to fit under their current funding envelope.

281

So now let's send Andy back to union yet again, because we have to talk about another big problem yet again

282

so our train is going to leave in 20 seconds

283

it's perfect let's click board train let's speed up time a little bit

284

and let's see if andy perfect is moving

285

and he's on his way back to union station in addition

286

to needing to overhaul the entire union station rail corridor union itself does not have enough tracks

287

or platforms to be able to handle more trains passing through it.

288

Metrolinks knew that of course, so in November of 2020 they signed an agreement for a project called USEP,

289

which stands for Union Station Enhancement Project.

290

The idea is to widen the existing platforms, add two new tracks on the south side of the station,

291

and also dig out a brand new concourse that will connect

292

Bay Street and York Street.

293

Four companies are in charge of this project.

294

They're called OnTrack Alliance.

295

There are two American contractors, Kiewit and Alberici, doing the construction.

296

There is also Canadian WSP doing the design and a Kiewit subsidiary called Mass Electric Construction Canada doing the signaling.

297

So it looks like Andy is currently almost at Union Station.

298

So let's take a look progress.

299

Well, construction has been going on since 2022, and you can see how much wider

300

Union is going to be.

301

East of the station, they also installed brand new bridge spans over Jarvis and Charburn, so now the corridor can go from six tracks to eight.

302

Now, the On -Track Alliance signed a $562 million agreement to deliver these upgrades,

303

but the official completion target was fall of 2025

304

so they are at least already a year behind

305

but metrolinks is saying that

306

when all of these upgrades are going to be complete union

307

will be able to handle up to 80 trains an hour

308

that is four times more versus what it handles today now andy is going to stay at union

309

But we still haven't talked about four lines.

310

Let's start with Milton, because it shares a problem with Kitchener, where across both of those lines, go runs on tracks that belong to freight railways.

311

But politicians came up with a solution, and that solution is called the missing link.

312

Basically, build a brand new freight railway between Milton and Bramley, put freight trains onto it,

313

and suddenly, both of those corridors are free for go.

314

And in January of 2025, Doug Ford, who is the Premier of Ontario,

315

he told Metrolinks to study it under a new name called GO 2 .0.

316

But at this point, it's just that, a study.

317

Then there's Barrie.

318

It was supposed to be one of the five electrified lines, but there's real progress though,

319

because the $175 million Davenport Diamond Guideway is complete, so now GO can fly over the freight tracks,

320

and also two new stations are under construction.

321

But the overhead wires pushed to an undated phase two.

322

But what's interesting is that Metrolinks is now saying that, at least in the meantime, Barry riders will experience longer travel times.

323

Because those two new stations, well, they add two stops.

324

And diesel locomotives, they need to accelerate, stop, and then get going again.

325

So all in all, the trip time is going to be slightly longer.

326

Richmond Hill is quite simple, with five trains in the morning and then seven in the afternoon.

327

Portions of that line also share tracks with freight railways, but it also runs along the bottom of the Don Valley,

328

which tends to flood from time to time.

329

Like in 2013, people had to be rescued from a train by boat.

330

So fixing all of that would cost a lot of money.

331

So this line is not in the electrification plan, it's not in the 15 -minute plan, it's not really part of any plan.

332

And Stoveville, it's partly double -tracked already, with the target of a train every 15 minutes all the way to Unionville.

333

But it's deferred from electrification, just like Barrie, and it also shares the corridor into Union with Lakeshore East, so essentially it inherits every single

334

Union station problem that we just talked about.

335

So if you're keeping track, Lakeshore West and East, they are getting electrified, at least partially.

336

Then Kitchener, Barrie, and Stouffville, they were promised electrification but that has been pushed into an undated phase two

337

and finally milton and richmond hill they are kind of stuck behind the freight train

338

so to conclude ontario was promised a european style railway with five electrified lines

339

and trains running every 15 minutes all day in both directions originally done by 2032

340

and to be fair a lot of work is actually being done with brand new tracks stations bridges

341

but electric trains themselves are still up in the air only

342

two lines at least as of today will be electrified instead

343

of five a german railway was fired half a billion dollars written off union stations roof

344

that is way too low

345

and no decision has been made on what to do about it

346

and the finish line that slipped all the way to 2042.

347

is go expansion dead Absolutely not.

348

But is it what Ontario was promised?

349

Not really.

350

But now I wanted to hear from you.

351

Today this was probably the most challenging video that I put together.

352

I tried to be as accurate as possible, but if you noticed any mistakes or inconsistencies,

353

please feel free to let me know down in the comments.

354

Thank you so much for staying all the way to the end of this video.

355

I hope to see you next time and bye bye.

日本語話者が苦手な音：

/r/ と /l/ の区別 — /l/ は舌先を歯茎につけ、/r/ はどこにもつけない: rail /ɹeɪ(ə)l/, railway /ˈɹeɪlˌweɪ/, naturally /ˈnæt͡ʃ.(ə.)ɹə.li/, electricity /ɪˌlɛkˈtɹɪsɪti/, roughly /ˈɹʌf.li/
/v/ — /b/ にならないように、上の歯を下唇に当てる: overhead /ˈəʊvəˌhɛd/, locomotive /ˌloʊkəˈmoʊtɪv/, arrive /əˈɹaɪv/, versus /ˈvɝsəs/, convince /kənˈvɪns/

シャドーイングとは？英語上達に効果的な理由

シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
