The Ulster Transport Authority Multi-Purpose Diesel (UTA MPD) was a diesel powered railcar, used in Northern Ireland. It was developed by the Ulster Transport Authority (UTA) as a progression of the earlier Multi-engined Diesel (MED). The MED concept, while suitable for short commuter links, was not considered so for the Northern Counties Committee section, with its main line from Belfast to Derry where speeds of up to 110 km/h (68 mph) were required. A new railcar development was needed, and the MED was superseded by the MPD.
