Swansea Maliphant Depot, also known as Swansea Train Maintenance Centre (Welsh: Depo Cynnal a Chadw Trenau Abertawe),[1] is a railway depot built for AT300 units from the Hitachi A-train under the Intercity Express Programme.
The depot is situated north of Swansea railway station by the South Wales Main Line.
Having been used as sidings until 2016, the depot is presently operated by Agility Trains as part of their contract to maintain the Class 800 fleet for Great Western Railway.
[3] The original facilities included a workshop, turntable, and carriage shed.
[4] It was first announced in 2012 that the current sidings were to be the site of a new service depot for Great Western Railway's new AT300s from the Intercity Express Programme, with construction due to start in 2015.
