37607 & 37612 approach Standish Junction on 8 July 2015 with the Pathfinder Tours 1Z40 06:12 Bristol Parkway to Dereham 'Norfolk Explorer' railtour. The 37s were a last minute replacement for the unavailable booked Class 20s. Although this location gives the impression of a four track mainline, it is in fact just a half mile section where the Bristol to Gloucester former LMS route runs side by side with the former GWR route from Swindon to Gloucester.
