This trip is scheduled to be hauled by a vintage diesel locomotive, likely to be a British Rail Class 47, 37 or 33.
The British Rail Class 47 is a class of British railway diesel-electric locomotive that was developed in the 1960s by Brush Traction. A total of 512 Class 47s were built at Crewe Works and Brush's Falcon Works, Loughborough between 1962 and 1968, which made them the most numerous class of British mainline diesel locomotive.
The British Rail Class 37 is a diesel-electric locomotive, which entered service from 1960. Also known as the English Electric Type 3, the Class was ordered as part of the British Rail modernisation plan.
The Class 37 became a familiar sight on many parts of the British Rail network, in particular forming the main motive power for Inter-City services in East Anglia and within Scotland. The Class 37s are known to some railway enthusiasts as "Tractors", a nickname due to the agricultural sound of the diesel engine of the locomotive.
