The British Rail Class 318 is an electric multiple unit (EMU) passenger train which operates in west central Scotland.
Following the withdrawal of the Class 314 fleet in 2019, these units are the oldest working EMUs in Scotland, having been in revenue-earning service for more than 38 years.
The units run on the standard 25 kV AC overhead line system, and are standard-class throughout.
Between 2005 and 2007, all Class 318s underwent a refurbishment by Hunslet-Barclay which involved the removal of the corridor connection on the driving cars allowing the provision of a full-width driver's cab.
