The Great Marquess and 2005, ran exactly 100 years to the day after the first passenger train to Fort William. From the earliest Railtours, carriages from the SRPS collection were a feature of these trains. In the 1970's several pre-Nationalisation vintage coaches were used on Railtours, including the North British Railway Saloon, Great North of Scotland Royal Saloon, Gresley Buffet, Caledonian and LMS coaches. These carriages, repainted in maroon livery, are maintained by members at Bo'ness, the only volunteer group to maintain a set of passenger coaches to the high standards required for running on Railtrack lines. A feature of SRPS Railtours is the catering .
Meals are prepared in the kitchen car and served to passengers at their seats.
On some trains over 800 meals are served. There are also two buffet cars in the train. Since 1992 a computer ticketing and seat reservation system has been used, and this also gives detailed information on meal requirements. When not required for SRPS Railtours the train is available for charter by other organisations . In recent years such charters have taken the coaches to the South and West of England.
