Update: I changed my mind -- I won't be at this meeting. I'll be at the Santa Cruz County Regional Transportation Commission meeting instead, where they'll discuss how to spend the ARRA "stimulus" funds on transportation projects.
In February, the Caltrain board accepted a resolution to add more bike space to existing bike cars. About three weeks ago, a Gallery "old style" bike car appeared with 4 seats removed and two bike racks added. You'll see the extra racks toward the back of the car.
See also that these racks are shorter than the existing racks. According to Caltrain's Mark Simon, the shorter racks are to enable access to the emergency exit windows.
There's some concern that the shorter racks won't secure the bikes as well and may scratch the bike frames, though any bike on Caltrain will get scratched and dented no matter what. I've only seen the racks once (I got to the station early one morning and boarded four different trains looking for the modified gallery car) so I can't comment on how well these shorter racks work.
What are your thoughts on these experimental shorter racks?
