The 4468 Mallard is an A4 steam locomotive built in 1938. With it's sleek, streamlined design which was very different to the engines built before, it was used primarily for the transport of express long-haul passengers at very high speeds along the east coast mainline, between Edinburgh and London's Kings Cross Station.
The trains on the British rails were generally restricted to a speed of 90mph. But in July of 1938, the Mallard broke the land speed record for steam locomotives by clocking in at 126mph. This plaque is to be found on the side of the engine, and was fitted after the end of World War II.
84 years later, this record is yet to be broken.
The Mallard locomotive and it's tender are 70ft long, and weighs 165T. It's painted in garter blue and has red wheels with steel rims. However, during the war, the engine was painted black.
The engine burns 1T of coal at all times and has a water capacity of 5,000 gallons. The train's boiler is 6.5ft in diameter. The steam guage can measure a maximum pressure of 300lbs/sq. in., but at its optimum, the driver should maintain a pressure of around 250lbs/sq. in. in order to enjoy the maximum amount of power. The Mallard's tender can carry almost 8T of coal.
True to the British quirkiness surrounding their tea, there is a small shelf right over the door to the firebox where the driver keeps oil, ensuring that the oil stays warm; along with a small caddy of tea, which also stays hot throughout the journey.
At the point of it's retirement from service in April 1963, it had covered almost 1.5 million miles. After complete restoration at the Doncaster Works, the Mallard is now on display at the National Railway Museum in York.
And finally, why "Mallard"? There are several British locomotives named after birds. These include the Osprey, the Golden Eagle, the Peragrine, the Kingfisher, the Falcon and the Merlin. When Sir Nigel Gresley designed this engine, he lived in a property that had a moat around it, which was frequented by ducks.
It was also probably meant to suggest its ability to travel swiftly through the air.
The Mallard has been celebrated in several British postage stamps over the years, given its iconic standing in the history of railways. This stamp was issued in 1988, and is one of 4 stamps which made up a series on transport and communication in the UK.
