They were a late follow on from the GSR Class 333 originally built by the Great Southern and Western Railway (GS&WR) in 1907/1908.[1]{{rp|113–115,269–270}} Design and modificationsThe locomotives were essentially modelled on the 1927 rebuild of Locomotive 338 of Class 333.[1]{{rp|113–115,269–270}} The {{Convert|5|ft|8+1⁄2|in|mm}} driving wheels and less than 16 long ton maximum axle load were suitable for go anywhere and secondary passenger and mixed duties as opposed to the {{Convert|6|ft|7|in|mm}} driving wheels of classes 301 through 321 which were more suited to express passenger work. ServiceIn practice all members of these classed were treated interchangeably for operational purposes. A {{convert|16|LT|MT}} maximum axle load allowed the class to be used almost anywhere. They were assessed in 1948 as quite powerful and fast and especially useful for passenger specials.[1]{{rp|113–115,269–270}} Loan to GNRIIn 1946 Locomotive 346 which was an oil burner at the time was lent to the Great Northern Railway (GNRI) to operate the Dublin-Bundoran express as far as Dundalk.[1]{{rp|270}} References1. ^1 2 3 4 {{cite book|title=Locomotives of the GSR|isbn=9781906578268|last1=Clements|first1=Jeremy|last2=McMahon|first2=Michael|year=2008|publisher=Colourpoint Books}} {{Ireland Steam Locomotives}} 3 : 4-4-0 locomotives|5 ft 3 in gauge locomotives|Railway locomotives introduced in 1936 |
