Mallard

Mallard is is the world's fastest steam engine, holding a speed record of 126 mp/h. He is a very popular exhibit at the National Railway Museum and is very well looked after.

History
Mallard was built on March 3rd, 1938, at Doncaster, where Gordon, Flying Scottsman, Spencer, and Green Arrow were built. On July the 3rd of that year, while undergoing tests, he established a world speed record of 126 mp/h.

After the decline of steam, Mallard was immediately preserved and put on display at the Museum of British Transport in Clapham, London.

Bio in the New Railway Series
Mallard came to host the Railway Choice Awards. He was crushed when he found out that his brother, Spencer had won the award instead of Gordon. Gordon was upset until Mallard came and gave Gordon the trophy instead after finding out that Spencer had cheated to get in.

Personality
Though in the original railway series, Mallard came across as stubborn, he seems to have some generosity in him when he brings Gordon his award for Fastest and Best.
