They were designed to be very fast and had a very sleek shape. One of them, 4468 "Mallard", is the fastest steam locomotive ever made. It set a world speed record of 126 mph (202.7 km/h) on July 3, 1938.
Six A4s still exist today. The rest were scrapped when steam stopped being used to power trains in Britain.
