BLAENAVON'S Heritage Railway is getting ready to step back in time to the 1940s, when the country faced it's darkest hour, radio was king and the only spam came in tins.

This weekend, July 7- 8, the railway is holding its annual 1940s weekend, based around the railways main station at Furnace Sidings with war department steam locomotive 71515 in operation.

Look out for war work, spies, spivs, troops, vehicles, bomb-disposal, stalls, dancing, make-do-and-mend and wartime food, as well as the bombed out house and wartime garden.

See the German plane that's crashed at the railway and help search for the pilot.

It is free entry to the event but normal prices apply to train tickets. Children will get a war time ration of sweets so why not enter into the spirit of the event and dress up in period costume.
