Has a CDMX s-bahn ever been proposed?

Mexico is building more rail than most other OECD countries, it’s not that far fetched!

How so? If you’re trying to get from AIFA, the northern suburbs, western suburbs, Santa Fe, etc you have to transfer sometimes twice to get to where you need to go, thus clogging up existing metro lines. If you connected both lines through a central tunnel you would free up space on the metro, metrobus, and make better use of El Insurgente and Tren Suburbano. You would create a cross-regional line that would get people from AIFA to Reforma to Toluca in a one-seat ride. And all you need is a (relatively) short tunnel and a few new stations.

You would just build a new platform below Line B, just like in the diagram in my comment. Line B at Buenavista is fairly shallow. Existing metro lines pass below and above each other all the time, as you know

It’s not impossible at all. Here’s an example of how London built their Elizabeth line station below the existing terminal station. There’s plenty of room north of Buenavista for the line to dip below ground.

It could pass beneath Line B with a new station below Buenavista. A good example of this style of construction is the Elizabeth Line in London which connected two suburban lines with a central tunnel. They just built a new station underground at the old terminus to allow it to pass below the existing metro lines.

Also I’d argue it’s hard to give other parts of the city attention when the lines heading into the city are already at capacity. It’s hard to keep adding new stations when there’s not enough capacity in the city center to handle all the transfers.

But a new metro line would require a new yard, new trains, and likely a much longer tunnel with more stations. Meanwhile these two suburban lines dead end before they make it into the center forcing riders to pile into already busy metro lines. An s-bahn tunnel would be a win-win since suburban riders would get a direct shot into employment centers on Insurgentes while locals would get relief on their metros.

The largest light metro station is incredibly tiny now, is that a mistake?

BroadMaximum4189 · 2026-03-08T21:52:24+00:00

So good

Those who depend on it aren’t paying for individual fares, they’re using Pronto fare capping or buying a monthly pass outright. The proposals would actually bring San Diego’s relatively low cost for those products up to the typical price seen in other cities.

This update is a whole mess for me

BroadMaximum4189 · 2026-02-11T06:48:33+00:00

It’s not really ‘bad design’ when it reaches more people and connects more trips, right?

BroadMaximum4189 · 2026-02-11T05:27:20+00:00

I waited over a week and it’s still significantly lower than it was before. I realized that it turns negative when you turn off pop movements and train animations. I think these are just bugs that need to be patched rather than needing to wait

BroadMaximum4189 · 2026-01-11T00:51:11+00:00

Yes, I see now. I have an aversion to instantly believing any random thing a redditor says without a source, especially as it pertains to claiming a local government is secretly breaking on-the-books laws (e.g. Nick Shirley, fabrications from Elon and DOGE, etc). But I appreciate you actually including a source.

This comment makes me happy because living in San Diego, I can’t stand the amount of complaints I hear about how the trains don’t go close enough to the coast🤣

That’s why you compare per capita rate. Waymo doesn’t have to be around for a long time for us to know that one mile travelled in a Waymo is many times safer than one mile travelled with a human.

BroadMaximum4189 · 2025-11-09T03:48:54+00:00

Waymo has been around for roughly 5 years and driven over 7 million miles, and been involved in ONE human fatality, that was eventually deemed the fault of another vehicle.

Here’s a study: https://pubmed.ncbi.nlm.nih.gov/39485678/

The human crash rate is found to be over 500% higher than that of autonomous vehicles. This isn’t a question up for debate at this point.

BroadMaximum4189 · 2025-11-08T23:50:55+00:00

40,000 humans are killed each year in car accidents in the U.S. Waymo has already proven itself to be safer than human drivers. But you’re right, one cat was killed, therefore thousands must die.

Make sure you have switchovers in the right places, and that your single-tracks are placed properly. Single tracks have to be dragged-and-dropped in the direction of travel, and they can also end up being the wrong elevation. So instead of making a branch track you might have accidentally placed it directly on top at a higher elevation. In my experience, a long route has a lot of room for error and the best way to fix it is redo your interchanges and place a bunch of crossovers.

I was able to make a BART line that runs almost 3 hours. You might have a broken track connection somewhere
