In 1946 the recently formed CIÉ built 5 diesel shunters to allow the withdrawal of a few decrepit tank locomotives. These locomotives were originally numbered in order with steam locomotives, however they were later just designated the D class.
Technical Information[]
These locomotives were of a six coupled wheel arrangement and were fitted with a Mirrlees TLDT6 engine of 487 b.h.p and two Brush traction motors on the outer axles. They had a top speed of 25 m.p.h and weighed 53 tons with a maximum tractive effort of 24000lbf. Interestingly these locomotives didn't have electric headlamps, light was provided by two kerosene lanterns on each end.
Disposition[]
Two class members were withdrawn in 1960 with the rest following in 1972, all were scrapped in March 1977.
