No heat 31191 was one of seven Class 31s acquired from EWS in April 1998 by Fragonset Railways along with 31186, 31459/468 and 31549/552/558. Originally stored from Toton in October 1995 it was returned to the fray courtesy of the Birmingham Railway Museum at Tyseley in June 1999 renumbered as 31602 the second member of the new Class 31/6 sub class, which included a repaint in Fragonset’s striking black livery with maroon/gold stripe and the mythical creature-themed name Chimaera. The only modification to justify the renumbering was the fitment of through ETS wiring allowing double heading with an electrical train supply-equipped Class 31/4, or for shutting down the ETS on the rear locomotive in case of fire while leading in a top and tail formation.
