Two of BART's busiest San Francisco stations could be on track for a $900 million expansion, complete with new tunnels, elevators and extra platforms to boost rider capacity.
The rebuilding of the Embarcadero and Montgomery Street stations would require tearing out the existing walls, installing new platforms, boring additional tunnels for staircases, and putting in extra elevators.
For added safety, the new platforms would have automated sliding glass doors that would open when the trains arrive.
The whole job could take more than five years, but the stations would remain open during that time.
The plan, floated by staffers at a BART directors retreat last month, is intended to accommodate the transit system's ballooning ridership.

Of those, more than a third of the system's total riders - about 150,000 a day - get on and off at the Embarcadero and Montgomery stations.

In five years, BART predicts, weekday ridership could hit 500,000 - making the two stations' improvements "mission critical," according to a staff analysis.
BART General Manager Grace Crunican has already proposed buying as many as 1,000 additional cars and a new control system to increase the number of trains that can run through the Transbay Tube to 30 an hour in each direction, from the current 24.
But to speed up the trains, BART needs to relieve the bottleneck in the Financial District stations. Any big glitch in the system, and the platform gets so crowded now at rush hour that service can actually slow down, as operators wait for the crush of people to sort themselves out.
Hence, the idea of new "saddleback" platforms - one in each direction at Embarcadero and one on the eastbound side at Montgomery - to allow riders to board and exit simultaneously from both sides of a train.
