In addition to building and maintaining trains, locomotives, buses, and trucks, the works achieved a number of notable engineering accomplishments. These included "armoured vehicles, armour-plated trains, experimental battery trains, turf-burning locomotives [and] munitions". Whilst Inchicore did not initially build locomotives, by 1851, with the expertise by then accumulated, the GS&WR board felt this was now practicable and in 1852 the first locomotive, an
0-4-2 number 57, entered service. In the 1920s and 1930s, in conjunction with
James J. Drumm, engineers at the works created the "
Drumm Battery Train" using
electric storage batteries. These ran generally on services to
Bray in the period 1931-1949. Issues with the supply of quality coal from 1941 precipitated some experiments with
turf burning and other initiatives. Further coal supply issues in 1946 resulted in a conversion of a number of locomotives to oil burning in 1947 and 1948. Increased availability of coal, and issues with oil prices, led to these being converted back to coal from 1948. In 1957, despite the dieselisation programme then being underway, an experimental turf burning locomotive,
CIÉ No. CC1, was constructed but never entered full service. It was the last steam locomotive constructed at Inchicore and the last steam locomotive constructed for the commercial railways of Ireland. In 1951, the
CIÉ 113 Class was built at the works. These were the first mainline diesel locomotives in Ireland. ==Proposed site developments==
