Class 47 Compilation ~ Thrash included!

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.

They were fitted with the Sulzer 12LDA28C twin-bank twelve-cylinder unit producing 2,750 bhp (2,050 kW) - though this was later derated to 2,580 bhp (1,920 kW) to improve reliability - and have been used on both passenger and freight trains on Britain's railways for over 50 years. Despite the introduction of more modern types of traction, a significant number are still in use, both on the mainline and on heritage railways. As of October 2016, 81 locomotives still exist as Class 47s, with further examples having been converted to other classes; 30 retain "operational status" on the mainline.
