DW&WR 42 to 44, built in 1883, were a set of three 2-4-0T tank locomotives built by Beyer, Peacock & Company for the Dublin, Wicklow & Wexford Railway in 1883, and the first for the railway with side tanks.[2] For their size they were considered to be very capable. In particular No. 44 was overhauled at Dundalk works in 1923 and was regularly allocated then to the 5.15pm Greystones express which usually consisted of size bogie coaches. Upon amalgamation to the Great Southern Railways (GSR) in 1925 it was determined these locomotives would be withdrawn and they were not allocated GSR locomotive numbers or class codes however despite this No. 44 was permitted to run up to 1927.[Note 1][1]
^The rebuilding of five 2-4-2Ts in 1925 and 1926 would have helped towards ease the severe motive power shortage in the former DSER suburban area at this time and explain while No. 44 was kept until 1927.
