It's the fastest steam locomotive that has ever been built, a wonder of engineering and is still a crowd-puller 75 years after its record-breaking run. On July 3, 1938, the Mallard reached speeds of 126mph along the East Coast Main Line and broke the world steam record - one that still stands today. On the 75th anniversary of that historic journey, the National Railway Museum and the Daily Mirror have teamed up to produce a special souvenir publication. Rare images from the archive help tell the fascinating story of the Mallard and the development of the railways over the past 200 years, from Stephenson's Rocket and the Flying Scotsman to the trains we travel on today. Priced just GBP4.99, Magnificent Mallard pays tribute to the people who turned the engine into a record breaker, from designer Sir Nigel Gresley to the driver who steered it into the history books, and celebrates the reunion of the six surviving A4 locomotives at the National Railway Museum in York.
