GWR 2-8-0 on a down express at Exeter St David's

When were car ferries from Dover to France £4? That's when this was taken!
Taken at Exeter St. David's, on 31.7.1954, 4706 on the 6.40am Leicester to Paignton Summer Saturday service.
It's a nice photo of heavy goods engine, with a big load on, sporting an express headcode.On summer Saturdays heavy goods engines were often drafted in to supplement the passenger locomotives.
