Waterford & Tramore 0-4-2 Locomotives in Ireland
Class Details by Steve Llanso of Sweat House Media
Class 4 (Locobase 10716)
Data from "Tank Locomotive, Waterford & Tramore Ry," The Locomotive Magazine, Vol XV (15 June 1909), p. 114-115.
The Waterford & Tramore was an independent short line that connected Waterford to the seaside resort of Tramore. It was opened in 1853, incorporated into the Great Southern & Western Railway in 1925, and finally closed by the C=ras Iompair +ireann (CIE ) on 31 December 1960. (According to Wikipedia, the last train did not run that night as the CIE wanted to avoid any demonstrations against the closure. There was indeed much distress at the move, as revealed in the Parliamentary debates of 16 February 1961 archived at [
].)
This tank replaced a much older single-drivered tank locomotive originally produced by Edmund Bury.
