While it was just recently that I posted about the planned upgrades to BART that will come just in time for BART's expansion to San Jose, there are already some other great ideas out there that would be nice to have in our mass transit system. London is going to start getting next generation trains for several of its lines in 2022, and there are three great ideas that I would love to see incorporated into BART.
1.) Autonomous Trains - Improved safety, reliability, and a permanent end to BART strikes.
2.) Continuous Trains - Instead of having a series of connected cars, the new tube trains will be one single super-long cabin that can bend. This substantially increases capacity and access.
3.) Safety Doors - There will be no chance of falling onto the tracks since there will be a second set of door that are synced with the trains and only open when there is a train parked at the station.
See the video below for a sneak peak at what is coming next decade to London. Note several elements of the new London trains are incorporated into the new BART trains like more doors and digital signage.
