Below are the names and numbers of the steam locomotives that comprised the LNER Class D49, that ran on the London and North Eastern Railway network.
Most names were local to the areas of Scotland and the North of England where the locomotives were based, but some were out of area, while a few were nowhere near the LNER network.
D49/1 (Part 1) locomotives were built with 8-inch (200 mm) piston valves, activated by Walschaerts valve gear for the outside cylinders, and Gresley conjugated valve gear for the inside cylinder.
D49/3 (Part 3) locomotives were built with Lentz oscillating poppet valves activated by Walschaerts valve gear.
D49/2 (Part 2) locomotives were built with Lentz poppet valves activated by rotary cams.
