The Córas Iompair Éireann 401 Class locomotives were built in 1957–1958 and designed for use on branch line traffic and shunting.
They were fitted with a Maybach MD220 engine of 420 hp (310 kW), with diesel hydraulic transmission via a Mekydro KL64 transmission, and were of C wheel arrangement.
They were numbered E401–E419, and were withdrawn from service between 1968 and 1977 and none were preserved.
[1] The E401 was available as a resin model from "Q Kits",[2] but this company is no longer trading as the owner has retired.
A 401 Body is now available from Shapeways via Valvedesigns (a Rapid Prototyping Service)[3]
