The Class 107s were initially built for suburban workings on the south side of Glasgow and the Class remained in BR's Scottish Region for its service life.

In later years, they were used almost exclusively on services radiating from Glasgow Central to such destinations as Barrhead, East Kilbride, and Kilmacolm, and - prior to electrification - on Glasgow/Ayrshire services (especially Largs).

[2] The class suffered from a structural problem, however, which could result in the bodies separating from the chassis under heavy braking.

Renumbered again to 107025-049 about 1990 to avoid similar confusion with new class 158s numbered in 7xx series.

For coupling codes see British United Traction Several examples of the class have entered preservation.
