The Class 33

Ordered in 1957 for British Railways’ Southern Region, the locomotives were known as BRCW Type 3s. Built as Bo-Bo mixed-traffic locomotives, they use 1550-horsepower Sulzer engines and can reach 85 mph. Their Crompton Parkinson electrical equipment gave them the nickname “Cromptons.”

The first locomotives entered service in December 1959. The initial batch of 65 was delivered by 1961, followed by a second batch completed by 1962, bringing the fleet to 98 locomotives across three main variants. The Class 33 became a regular presence across the Southern Region, especially the South Eastern Division, hauling passenger and freight services to Dover, steel trains between Sheerness and Willesden, cement runs and engineering trains. In the South West, some were fitted with SR multiple unit equipment for push-pull services to Salisbury and Weymouth that began at London Waterloo.

Twenty-nine Class 33s have survived into preservation, including some certified for mainline use. D6566 (33048) and D6575 (33057), “Seagull,” are operational on the West Somerset Railway in BR Green livery.
