Discontinued – Bachmann CL57/0 Diesel 'Restormel Castle' First Great Western Green

The British Rail Class 57 is a re-engineered locomotive, rebuilt by Brush Traction at Loughborough from redundant Class 47 locomotives between 1997-2004. They are fitted with a refurbished General Motors engine and a reconditioned alternator to improve reliability and performance. Enthusiasts have nicknamed the locomotives 'Bodysnatchers' because the body of the Class 47 has been stripped, rewired and re-engined. In 1997, Freightliner placed an order for six Class 57/0 locomotives, with the first being released in 1998. 12 named locomotives were built and finished in the company's green/yellow livery.

In 2002 Virgin Trains ordered 12 units classified as 57/3 with a revised power unit delivering 2750 hp enabling a top speed of 95mph. They were painted in the company's distinctive livery of red, white and silver and as their primary function was to act as emergency rescue locomotives, they were named after the characters in the 1960's TV series Thunderbirds. The order was increased to a total of 16 and all the locomotives were modified with automatic Delner coupling devices for use with 'Voyager' and 'Pendolino' units.

Brush Engineering developed a passenger demonstrator locomotive, a type 57/6 for the leasing company Porterbrook, which carried a very distinctive silver and purple livery. The locomotive was later purchased by the West Coast Railway Co and was painted in a plain maroon livery with black stripe. In 2003, First Great Western took delivery of four 57/6 locomotives, all named after castles, to work the Paddington to Penzance sleeper service.

In 2007, half of the Freightliner fleet was re-leased by Porterbrook to Direct Rail Services. Arriva Trains Wales obtained 3 of Virgin's Class 57/3 locomotives in 2008 and Advenza Freight purchased two ex-Freightliner locomotives, painted in the Advenza Freight livery.
