The Flying Scotsman was built in Doncaster for the London and North Eastern Railway (LNER) in 1923. It was designed by Sir Nigel Gresley and was to become one of the most powerful locomotives used on British railways. The locomotive has a top speed of over 100 MPH and was the first to reach that speed making it world famous. The Flying Scotsman’s unique features is a corridor through the tender enabling engine driver changeover without stopping the train, which in turn allowed the first non-stop 4 hour service between London and Edinburgh. Between 1st and 9th of April, the Flying Scotsman will be on the Keighley and Worth Valley Railway. The locomotive will be taking passengers between Keighley and Oxenhope on 5 return trips each day with around 250 passengers on each leg meaning that over 10,000 people will travel up and down the line that week, with many more spectators also expected up and down the route taking photographs. Standard seats are available but for an extra charge there are also Pullman seats. Each day one of two of the Pullman coaches, Mary or Ann will be attached to the train.
