Marching band music plays. Men in overalls work to restore the Great Western Railway Dukedog class Earl of Berkeley locomotive 3217, grinding and painting the engine. The front is painted with thick red gloss and the sides with dark green, once the old paint has been chipped away. The engine moves past the water tower at Sheffield Park Station. A man with a cine camera around his neck is one of a group of onlookers in attendance at the naming ceremony. A man makes a speech, standing with the Station Master, before a woman in sunglasses swings a bottle of champagne against the side of the locomotive. The train moves along the track, seen from the side of the track from a low vantage point, and above from a bridge as the train nears and passes below. The engine and carriages travel to Horsted Keynes, passing the signal box. Text closes the film; Earl of Berkeley, built at Swindon in 1936, now privately preserved on the Bluebell Railway in Sussex.
