The DW&WR 13 was an 0-6-0 goods locomotive class built in 1904 at Grand Canal Street railway works for the Dublin, Wicklow & Wexford Railway and was followed by four more of the same class, two being contracted to Beyer, Peacock & Company.
15 and 16 were originally meant to be enlarged version of this class but axle loading and the length of the Harcourt Street turntable led their designer Wild to a 260 mogul design that received the even more excellent report: One of the best Goods on the system, very powerful and reliable with low axleload.
[2]: 151–152 The main duties were goods services on the Wexford and Waterford via the DW&WR's route via Macmine junction which opened in 1905.
[citation needed][2] They also handled the day goods from Waterford to Dublin and found occasional use on passenger services and excursions.
While 442 was withdrawn in 1930 only 5 years after receiving a new boiler the remaining 5 locomotives lasted until 1955–1957 by which time CIÉ 1,200hp A and 500hp C diesels had been introduced.
