M&GN Class C 4-4-0 No 18 with a Cromer to Peterborough train with a through coaches to Kings Cross and Leicester in c1922.

Richard Thorne says "I believe this photo is taken near Weybourne on the M&GN line, which is now the North Norfolk Railway and it looks like a Cromer (Beach) to London (Kings Cross) express. The sea can just be seen in the background with the hill behind the loco smokebox being part of Sheringham Golf Course and coastal path.
This photo has been reproduced in a colour version as a well known post card image".
