The other day I was speaking to a Korean friend of mine and he was telling me about Seoul's new GTX-A commuter railway line. This line opened at the end of 2024 and is part of a broader Great Train eXpress initiative that includes 3 lines (A, B, and C) and that is intended to establish a new "30-minute commute zone" surrounding Seoul. A is the first line to open. C is scheduled for completion in 2030. And already, three more lines are now being planned: D, E, and F.

What this first line has accomplished is pretty extraordinary. GTX-A connects Paju in the north to Seoul in the south. Paju sits at the northern border of South Korea (and therefore houses many US and South Korean Army bases) and has a population of over half a million people. Prior to GTX-A opening, this commute used to take approximately 90 minutes by conventional subway and up to 90 minutes by car, depending on traffic.

Today it takes exactly 22 minutes! If you're interested in seeing a complete walking video of this commute, click here.

The GTX system is a higher-speed railway line. Meaning, the trains are designed to operate up to a maximum speed of 180 km/h. Average speeds vary depending on the segment and stop spacing, but it seems to operate at an average speed of around 100 km/h. Paju to Seoul, for example, is around 33 km. So at 22 minutes, that's a blended average of 90 km/h. This means that there's no faster way to travel between these two points.

What this also means is that, as new GTX lines continue to come online, the geography of the Seoul urban region will continue to get redrawn. Suburban regions that were previously far out, are now going to get "pulled in" and function as more integral parts of a contiguous city. This improved access should also alleviate housing pressures by effectively opening up more supply.

I mean, 22 minutes is nothing. It can take longer than this to travel 3 blocks on a Toronto streetcar during rush hour. GTX is a prime example of the magic of rail and what's possible once you accept that highways (and tunnels underneath them) aren't going to be what efficiently move the most number of people around a big global city.

It was announced this week that Metrolinx will be making changes to the popular UPX train service that connects Union Station to Toronto's Pearson International Airport. This is an interesting transit story. And as someone who will be moving to the Junction (adjacent to one of the stops along the way), I have a vested interest in this announcement.

The UPX started out as a high-priced boutique train service to the airport. A one-way fare was $27.50 per person (without a PRESTO card). This was too much and I argued that here on the blog. If you looked at the math and compared it to the alternatives, such as taking an UberX, most people were not going to take this train.

The fares were ultimately dropped -- by a lot -- and the service then took off not only as a link to Pearson but as an inner-city commuter service. I now sometimes call it the Union-Junction Express, because the actual train ride from Union to Bloor St (at Dundas West) is about 7 minutes once you're on the train.

The announcement this week merely solidifies the train's evolution from high-priced boutique service (which didn't work) to airport/commuter service (which is really working). The trains are expected to run more frequently now, some of which will continue to make the same stops as today and some of which will stop in new locations along the line.

As transit-advocate Cameron MacLeod said in the Globe and Mail yesterday, "there's both good and bad news here." The good news is more frequent service. Even quicker trips in some instances. And better integration with the broader GO train network. The bad news is the award-winning UPX station at Union will no longer be needed. The service is expected to move to a new platform.

Yesterday after my post on leveraging LRT, I stumbled upon an interesting and timely article written by Richard Joy, who is the Executive Director of the Urban Land Institute (Toronto).

The article talks about some of the transit-oriented development that we’ve seen at various nodes along Toronto’s Yonge subway corridor (St. Clair, Eglinton, Sheppard, and so on). But it goes on to argue that these are exceptions to the rule. For the most part, we’ve missed the boat:

The tragic history of our massive capital investments into transit infrastructure is massive under-development.

Indeed, the Bloor-Danforth subway corridor is a land use crime scene.

His main argument is that until we expand the supply of transit-oriented land (through increased intensification), we will continue to undersupply the kinds of walkable and transit-oriented neighborhoods that many, if not most, people actually prefer. And that, out of necessity, will force people into their cars. Because affordability trumps location preference.

As one example, he talks about the intersection of Bloor Street and Dundas Street in the west end of the city. Next to Union Station, this is probably the best connected mobility hub in the region. You have the Bloor-Danforth subway line, a streetcar line, and a GO regional rail line which all feed into it. Next year it’ll also become a stop for the new express train to Pearson airport.

And yet the city has a history of opposing intensification in this location, including the old Giraffe Condominiums proposed by TAS. Does that make sense to you?
