British Rail Class 318/3

The Class 318/3 subclass designation covers Class 318 sets that underwent a further stage of interior refurbishment, including the comprehensive refit carried out under the Abellio ScotRail franchise from around 2018 that brought the passenger environment up to a standard comparable with newer rolling stock. The refurbishment included new seating, revised saloon layout, updated passenger information systems, and improved accessibility features.
