This complete train set features two powered "A" cab cars, and two unpowered "B" middle cars, which can operate on any conventional HO scale track (18" curve radius required, 22" radius preferred). This is the DCC/Sound version of the train, which uses DCC track and features sound effects and smells recorded from real BART trains. Full underbody detail, including accurate electrical systems, conduits, and equipment boxes.
I am shocked to learn that, after 50 years, this is the first time that an HO scale BART train has been available. $749!
