> I wonder if there’s an opportunity for BART to switch to standard gauge in the future or as part of retiring trains, or if that’s even a good idea for cost savings?
I'm guessing it would be massively expensive, and it's not clear to what end they would change it.
It's not like they could then buy cheaper off-the-shelf trains, since the trains still have to be designed and built for the particular system in other ways, i.e. controls, propulsion, and custom interiors.
Also, BART doesn't share tracks with any other system, so there's no reason to do it for compatiblity's sake either.
