Locomotives of the London and North Eastern Railway
The London and North Eastern Railway (LNER) produced several classes of locomotive, mostly to the designs of Nigel Gresley, characterised by a three cylinder layout with a parallel boiler and round-topped firebox. It produced the most iconic locomotive of its day, 4468 'Mallard', the holder of the world steam locomotive speed record. It also built the world famous 4472 'Flying Scotsman'. However, its locomotive inheritance was much greater than just the 'A4 Class', it also produced highly successful mixed-traffic and freight designs.
