Great Southern & Western 2-2-2 Locomotives in Ireland
Class Details by Steve Llanso of Sweat House Media
Class 36 (Locobase 4807)
A Bury design with the haystack firebox, this locomotive was one of the first of the largest railway in Ireland. According to "Ireland's Railway Systems" (reproduced on Mike's Railway History website [
]), "This locomotive covered 487,919 miles in a quarter of a century of service, being withdrawn from service in January, 1874."
The photograph does indeed show a typical Bury design with the driving axle forward of the firebox, the haystack dome over the firebox, a horsecollar smokebox, tall stack, and spindly wheels.
