Originally built as A car 272 by Rohr, and among the last A/B cars to be delivered (July 1975). It was rebuilt in 2002 by Bombardier as A2 car 1272. It's looked a bit rough since 2017, with the "a" in "ba" faded alongside the Y end (cab) side numbers. Here it is, one sunny afternoon approaching Union City platform 2 on a Richmond train. Mission Peak, Mount Allison, and Monument Peak loom in the background.
"The Two Bagger" is meant to be a place to store more "blog" style posts on various cars, pictures, and random tidbits. At BART, a "two bagger" is a rather informal name for a two car train. Two car trains rolled in revenue service back in 1972.
