-New transbay tube
-More stations in SF and extensions in the East Bay and in the Peninsula
-More trains with more doors and no drivers. Also with flat screen TVs showing news and information riders might need
-Bigger, nicer, stations

Hey, what about flying trains?

BART based their plans on projections that say that we'll be seeing upwards of 10 million more people to the area by 2050 and the need to accommodate them. There's also the thinking that building a new transbay tube could help during another earthquake in case one of the bridges goes down (like in '89). That is, of course, if BART doesn't get wiped out by an earthquake.

The one hitch to all these fabulous ideas? Underground trolls Money, of course. But first, there'll be lots of studies to study the idea.
