The Great Southern and Western Railway Class 101, classified as Class 101 or Class J15 by the Great Southern Railways, was a class of 0-6-0 steam locomotives designed for working goods traffic although they did, and were quite capable of, working branch or even main line passenger trains.
The 101s were by far the most numerous class of locomotive (diesel or steam) ever to run in Ireland with 111 being built between 1866 and 1903 with only minor modifications between batches. The great majority were built by the GS&WR at Inchicore Works, though the construction of some examples was contracted out to Beyer, Peacock and Company (12) and Sharp, Stewart and Company (8), both famous Manchester based locomotive building firms.
The 101s survived long after many more modern steam locomotives were scrapped with nearly half their number still in traffic when the Córas Iompair Éireann completed dieselisation at the end of 1962.
The RPSI has an example, No.186

Two have been preserved by the Railway Preservation Society of Ireland making them the most numerous class of preserved Irish steam locomotives. No. 186 is currently in working order , and is normally based at the society's Whitehead depot.
- No. 186, a Sharp, Stewart engine, has a superheated larger boiler with a Belpaire firebox and tender no. 375, a larger 3,345 imperial gallons (15,210 l; 4,017 US gal) tender.
- No. 184 has a smaller saturated boiler with round-topped firebox, and was paired with tender no. 156, an 1,864 imperial gallons (8,470 l; 2,239 US gal) outside-sprung tender. To give a larger water capacity, No. 184 has been paired with the larger tender when used on the Irish railway network.
As built the locomotives would have carried the lined dark olive green livery of the Great Southern & Western Railway until around the start of the 20th Century. After that, they were black with red lining until the late 1910s, when they were painted all over unlined grey. This dull but all-encompassing livery included motion, wheels, inside frames, cabs, smoke boxes and chimneys. The only relieving feature was the red buffer beam. Standard cast number plates were also painted over grey, with rim and numerals picked out in cream or very pale grey, or occasionally not at all. This livery persisted post-1925 into Great Southern Railways days, and was extended to locomotives of other constituent companies after the GSR amalgamation of that date. On the formation of CIE in 1945, the only change was that the cast number plates were gradually removed and pale yellow numerals were painted on instead. In addition, most tenders received a lined pale green "flying snail" logo.
While CIE repainted a few locomotives in green or black, all of the J15 class remained grey until withdrawal.
The preserved locomotives have appeared in various films. Most recently, No. 186 appears in the 2006 film, The Wind That Shakes the Barley. Both 184 and 186 appear in the 1979 film, The First Great Train Robbery.
