Due to the strikes that took place at the GS&WR's Inchicore works in 1902, Superintendent Robert Coey had the class 355 built by Sharp, Stewart & Co. These were seven 0-6-0 freight locomotives, which stood out due to their high boiler. Their problem was that the first driving axle had a particularly high axle load.
Rebuilt to 2-6-0
Locomotive Magazine, March 1918
Therefore, from 1907 onwards they were rebuilt to the 2-6-0 wheel arrangement, with the axle load of the first driving axle now being slightly lower than that of the other two. Instead of a bissel axle, a leading axle with a radially adjustable bearing was used, and a longer smokebox was also installed. They were withdrawn between 1955 and 1960.
