Class 342 as built except where noted[ 1] : 113–115, 269–270
The Great Southern and Western Railway (GS&WR) Class 3334-4-0 mixed-traffic locomotives designed by Robert Coey and built by Inchicore railway works in 1907/8. In 1936, the successor company - the Great Southern Railways (GSR) - built five similar engines known as GSR Class 342 .[ 1] : 113–115, 269–270
Design and modifications
The design used the same taper boiler and 18 in x 20 in cylinders as Coey's express 4-4-0 express passenger engine 321 ; however, the smaller driving wheels and less than 16 long ton maximum axle load were suitable for go anywhere and secondary passenger and mixed duties.[ 2]
The later Class 342 locomotives were essentially modeled on the 1927 rebuild of locomotive No. 338 of the 333 Class.[ 1] : 113–115, 269–270
Service
In practice, all members of these classed were treated interchangeably for operational purposes. A 16 long tons (16 t) 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] : 113–115, 269–270
Loan to GNRI
In 1946, No. 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] : 270
