GWR 48xx/58xx/14xx 0-4-2 Auto Tanks
Built for push-pull and branch trains. The Collett 48xx/58xx class 0-4-2 tanks were built in the 1930s and represented a modernised version of the Armstrong 517 class engines (built 1868-85) they were to replace. The 48xx class were fitted with regulator control connections for push-pull or auto train working, while the 58xx class were supplied for lines where hauled coaches were used. After WW2 the 48xx number sequence was wanted for the oil fired 28xx 2-8-0s and the tank engines were renumbered into the 14xx series.
