The 113 class were the first mainline diesel locomotives built by the Inchicore Works. Their construction began in 1948 however shortage of parts meant that 113 was completed in 1950 and 114 was completed in 1951 instead of the projected 1949. Like the other Sulzer engined locomotives owned by CIÉ these machines had a short career compared to the locomotives that replaced them. One of the main reasons they were considered a failure was that their axle load was too high, all other sulzer engined locomotives CIÉ posessed were Six-Axled whereas these were of a Bo' Bo' wheel arrangement. Another reason they were a failure, as is detailed in the next section of the article, was their poor brakes which resulted in quite a few runaway incidents.
The 113 class locomotives were originally fitted with Sulzer engines of 915 b.h.p, these were uprated to 960 b.h.p in 1956, still putting down 721 b.h.p at rail. The transmission was provided by a "Metrovick" generator and Metrovick MV137CW traction motors identical to the ones used in the 001(A) Class, 101(B) Class, and 201(C) Class. They had a top speed of 55 m.p.h. They weigh(ed) 80 tons. Throughout their operating lives they suffered from chronic break leaks and later had to have chokes installed on the brake cylinders.
Current State of The ClassEdit
All the locomotives in the class bar the one in the picture(113) have been scrapped. The locomotive pictured has some fittings missing and the floorboards are all rotten but is otherwise intact, it survived because it was left in a siding in an attempt to block the sound emminating from the Inchicore Works. The locomotive has also been repainted into CIÉ green as it wore between the mid 1950s and about 1963. It had latterly remained in the subsequent livery of primarily black.The locomotive is currently in the Ulster Folk and Transport museum in Cultra.
