The Dublin and South Eastern Railway 15 and 16 were a pair of 2-6-0 steam locomotives which were built for the heavy goods (freight) traffic on the Dublin to Wexford main line of the Dublin and South Eastern Railway (DSER). The two locomotives were built by Beyer, Peacock and Company at their Gorton Foundry in Manchester.
On account of the risk of damage when new (during the Irish Civil War period of 1921–1922), both examples were initially sent to Belfast for safekeeping. They were stored by the Great Northern Railway (Ireland) at Adelaide yard until 1923, when they were returned to the DSER. The locos were withdrawn in the early 1960s.
In 1925, the DSER was absorbed into the Great Southern Railways and the two locomotives were renumbered 461 and 462, and placed in Class 461 or Class K2.
Originally painted DSER green, on becoming part of the GSR, they were painted in standard freight livery of unlined dark battleship grey. In the late 1950s, all-over unlined black was applied. This was the livery 461 carried, until her last overhaul with replica cast numberplates of GSR design, as carried in GSR years.
In preservation, No.461 has been outshopped in CIÉ lined green livery upon completion of her overhaul in 2011.
Preserved by the RPSI (Railway Preservation Society of Ireland), 461  was allocated to the Wexford goods and in Waterford, working beet traffic until its withdrawal in 1962, a year before CIÉ abolished steam locomotives entirely. It was presented by CIÉ to the RPSI in 1977. An extensive overhaul followed at Whitehead and the locomotive returned to traffic in late 1990. At present, the locomotive recently (2011) completed an overhaul at the RPSI's Whitehead base . Locomotive No.461 has appeared in theatrical film releases such as Michael Collins and Angela's Ashes.
