Transbay Terminal — yet another problem. Train space might be too small

San Francisco’s Transbay Transit Center may have a new problem on its hands — not enough room in its $700 million underground train station to handle the projected Caltrain rail service when, or if, it arrives . . . .

Caltrain expects to see its ridership more than quadruple over the next 20 years to 250,000 riders a day, once it converts from diesel to electric trains.

But now there are questions over whether there is enough room in the underground station to handle the 12 to 16 trains per hour Caltrain may need to run into the city to handle all those new passengers.

“Our initial analysis shows that at least 10 trains per hour can be accommodated in the terminal,” Murphy said. Meaning that Caltrain could be two to six trains short on platform space.

And that’s without high-speed rail, if it ever comes . . . .

Supervisor Aaron Peskin, who is also chairman of the County Transportation Authority, said San Francisco is committed to getting the tunnel built, even as federal and state funds are evaporating.

“We’ll find the money somewhere,” Peskin said.

I don't see this as a major problem. If, indeed, Caltrain needs to run more trains into the city than the capacity of the Transit Center, it can terminate and originate some trains at 4th & Townsend. Mission Bay is growing dramatically enough that many passengers may prefer to board or disembark there because they may live or work there.
