Sooooo much snark, and so little interest into what BART actually runs on!
Originally, BART was a master stroke of digital integration in the 70's, and it's digital voices announcing the next trains were a thing of the future: An early accessibility feature before we even knew what those were, really.

- bbaron63 1y agoI believe in one of the Planet of the Apes sequels, they used a BART construction site, because of how futuristic it looked.

- dredmorbius 1y agoA Streets of San Francisco episode, starting a very young Michael Douglas, was set in the BART tunnels, still under construction, as well.
- dlcarrier 1y agoI know what it runs on! It's a 5' 6" in gauge, usually used in India, and used no where else in the US.

The wider gauge solved(?) the stability problem, but at the cost of always needing custom rolling stock, but more importantly, making Bart build-out significantly more expensive and unable to take advantage of existing track. That hurts the viability of the Bart ecosystem.
- JumpCrisscross 1y ago> wider gauge solved(?) the stability problem, but at the cost of always needing custom rolling stock Why not use Indian rolling stock? Modern Indian metro trains are quieter and more comfortable than BART.
- rsynnott 1y agoIndian _metros_ generally use standard gauge. The BART _may_ be the only metro using this gauge in the world.
- smcin 1y agoFor rapid transits, 5'6" (broad gauge) is pretty eccentric [0] and was so back in 1964 when it was chosen; almost all other US rapid transits use 1,435mm/4'8.5". 5'6" is also doubly weird choice since tunnel diameter was one factor/excuse nominally used to object to tunnelling north to Marin County. Also it means the maintenance and carriage work can't easily be moved elsewhere. (It is the widest gauge in use of heavy-duty mainline railways in the world, but that's a separate thing). For comparison to other US rapid transit systems (almost all others use 1,435mm/4'8.5"), see table in https://en.wikipedia.org/wiki/Rapid_transit_track_gauge https://en.wikipedia.org/wiki/Rapid_transit_track_gauge and scroll down to "United States".
