A #class37 #37714 leading a #class31 #31108 at a recent Great Central Railway diesel gala event. It is great to see such a variety of preserved diesel locomotives at these types of events. They are all in such excellent condition and are a real tribute to the hardwork put in by the volunteer groups behind the scenes. #uktrainspotting #trains #diesellocomotive #britishrailways #railway #railways #trainspotting #heritagerailway | Adrian Watson

A glimpse inside the cab of the first class 37 locomotive built. This was built in 1960 and since entering preservation has been restored to as close to original condition as possible. It is a regular runner on diesel days at the Great Central Railway. | Adrian Watson
