GS&amp;WR Class 368GS&amp;WR Class 368 GS&WR Class 368 The Great Southern and Western Railway (GS&WR) Class 368 consisted of four 2-6-0 tender locomotives designed by Robert Coey for use on heavy freight trains. on the main line. The origins of class 368 lie with rebuilds of GS&WR Class 355. The class 355 consisted of eight locomotives and was designed by Coey as a more powerful version of GS&WR Class 351. They were constructed at the North British Locomotive Company as 0-6-0 due to industrial disputes at Inchicore railway works in 1903. Problems with the design immediately became apparent due to a  high axle load of over resulting in severe route restrictions and propensity to derail due to excessive weight on the front end. The whole class was converted to 2-6-0 "moguls" between 1906 and 1908 by addition of a leading axle which resolved both the issues of derailing and restrictive axle load. Class 368 was essentially based on the success of this conversion with the driving wheels being moved farther back and closer together.
