The Princess Coronation Class is a class of express passenger steam locomotives built by the London Midland and Scottish Railway (LMS) and designed by William Stanier. They were an enlarged version of the LMS Princess Royal Class. Several examples were originally built as streamlined, though this was later removed. The non-streamlined locomotives were often referred to as Duchesses, though to enginemen they were often known as Big Lizzies.
They were the most powerful passenger steam locomotives ever to be built for the British railway network, estimated at 3300 horsepower and making them far more powerful than the diesel engines that replaced them. #British #Class #Coal #Coronation #express #LMS #locomotive #passenger #Princess #Rail #railways #steam #train #transportation
