[citation needed] Initially, its purpose was to maintain the Class 303 and Class 311 rolling stock, which operated on the electrified services from Glasgow Central High Level to Gourock, Wemyss Bay, Motherwell via Rutherglen and also the Cathcart Circle and Kirkhill branches.

Electrification up until this point had been confined to Cathcart Circle and Newton/Neilston branches (May 1962) and the North Suburban lines (1960), with sets being maintained at Hyndland depot which opened in 1959.

Within the depot itself, Matterson lifting jacks were used to allow the changing of wheelsets and traction motors; a wallcrane aided the removal of pantographs and other associated roof equipment from the fleet.

Part of the expansion saw the extension of the maintenance shed by fully three coach lengths to allow for the additional passenger rakes into which the APT was formed.

Additional equipment was installed including a 15 tonne overhead crane, a purpose built wheel drop pit for removing the axles on the articulated bogies of the APT.

Following an announcement by Transport Scotland of the order of a new fleet of Class 380 EMUs, a £24m expansion of the depot got underway.

As part of the expansion, a new state of the art wheel lathe was also installed enabling faster re-profiling of rolling stock wheelsets.
