GWR Castle class 4-6-0 No 5023 Brecon Castle waits to leave Penzance with an up mail and milk train on July 9, 1953.

Peter Kerslake adds "This fine shot from the favourite vantage point here overlooking Penzance station includes the calm waters of Mounts Bay with the substantial rocks protecting the line also visible.
It's a quiet spell allowing time for a chat with the crew as Laira's 5023 Brecon Castle is heading home to Plymouth with a splendid variety of stock including a couple of milk tanks and a Travelling Post Office included in its substantial load".
