The CIÉ 8100 class were the first electrical multiple units used on the Dublin Area Rapid Transit (DART) system. Built by GEC and LHB (Linke-Hofmann-Busch) in 1983, they are two-car units, and were the only units used on the DART before the arrival of the 8200 Class. 40 two car sets were delivered, numbered 8101/8301 to 8140/8340. 81XX units are power cars while 83XX units are unpowered driving trailers. The driving cabs are full width, with the inner ends connected by gangways.
