OAKLAND (CBS SF) - BART has created an interactive research lab to obtain feedback on its future fleet of train cars, transit officials said.

The "seat lab" will be taken to community centers, events and BART stations to allow customers the opportunity to provide input on future designs.

KCBS' Bob Melrose Reports:

The interactive lab will focus on seat height, seat width, and legroom. Layout design, including accommodations for bicycles, luggage, and people with disabilities, will also be addressed, transit officials said.

"BART has the oldest fleet in the nation now, so at some point in the near future, we must replace the vehicles in order to maintain our 95 percent on-time performance," said Bob Franklin, BART board president.
