Compass Tours was a UK railtour organiser specialising in excursions with heritage diesel locomotives such as the Class 37, Class 40 and Class 47 and also using Steam Engines such as the LMS Black 5. A pro-rail company, Compass Tours heavily promoted the advantages of rail as a mode of transport, encouraging passengers to leave their cars and take the train. Nearly 300 tours were organised by the company, with many thousands of passenger journeys being taken. The tours were typically very popular, carrying between 400-600 passengers in up to 13 vehicles of Mark 1 or Mark 2F coaching stock.
