The Class 66 was based conceptually on the Class 59, a US/Canada built freight locomotive bought in small numbers by private companies to haul trains in the latter days of British Rail. The 66 uses the same body shell meaning there are many aesthetic similarities to the 59 but the 66 has a different engine model and traction equipment .
(66/9) EMD 12N-710G3B-T2
|Power:||3 ,300 hp (2, 3460 kW)|
The Class 66 was initially ordered by EWS (now part of DB Cargo) in the early days of rail privatisation, the first order was for 250 with subsequent carry-on orders continuing until 2016 when the final batch arrived in the UK. No further new 66s are likely due to changes in EU emission rules (they arn't the only new build locomotives to fall foul of this). Further locomotives have been built by EMD for operators in Europe and elsewhere, some of these being later imported to join the British fleet.
The very final Class 66 or "Shed" as they are known by enthusiasts was painted in British Railways lined green and named "Evening Star" after the last steam locomotive built for British Railways , some might say that "Evening Shed" might be a more suitable name of course!
