One guy worked in the central computer (room) at Lake Merrit (started before it was built), another was in buidlings and grounds -- I used to lunch with him occasionally around the time that B&G supervisor committed suicide after getting caught hiring illegal aliens to use hazardous chemicals to clean the stations, a third started out in Hayward shops and spent a lot of time in Chula Vista while the cars were being built in Mexico, a fourth is an instructor and is nearing retirement. I also know where all Allen's papers are. BARTD is a bureaucracy and therefore innately inefficient. Take your blinders off.
