The GNR(I) had introduced the T1 class numbered 185–189 in 1913. They were designed for both suburban services and longer runs such as Dublin to Drogheda and Belfast to Armagh. They proved so successful that a further twenty were commissioned in 1921, 1924 and 1929. Although externally identical in appearance to the T1, they were classified as the T2 class having larger tanks and higher boiler pressure, and were used successfully on both fast passenger work and freight.
ModelThe T2 is currently available as a 00 gauge etched-brass kit from Studio Scale Models. It includes transfers, brass etches, most nameplates and cast white metal parts. References
