LMS Coronation 4-6-2 No. 46226 Duchess of Norfolk with Class 5 4-6-0 No. 45461 at Perth station. In summer the 09.25 Crewe-Perth continued to Aberdeen after a loco change at Perth with a 63A loco taking 4 coaches forward. The 09.25 stopped at the north end of Platform 7. This looks like 46226 is coming off with 45461 taking over, in late summer, judging by the light. Dated sometime after Perth's re-signalling.
