In July 1957, locomotive No. No. 67338 was used for a series of tests into the performance of concrete sleepers when trains were derailed. These tests took place between Halifax and Keighley, Yorkshire.
None of the G5s was preserved, although a new build is in the works at Darlington. Despite other locomotive project being classified as "New Builds", this one is destined to be a replica of original class member No. 1759.
