For the branch line between Gortatlea and Castleisland in Kerry County, the GSWR had two vehicles built in Inchicore in 1890, which can be described as precursors to the steam railcar. Since commercial traffic with regular passenger trains could hardly be carried out on the line, an extra light tank locomotive was combined with a passenger compartment. However, according to Locomotive Magazine, issue May 1903, the passenger compartments were not actually used for their intended purpose.
