The CIÉ 8100 class (also known as the 8300 class) were the first electrical multiple units used on the Dublin Area Rapid Transit (DART) system. Built by GEC and 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. Power cars always head north, while driving trailers head south.
