text: For half of the year the company also uses part of Fort William depot as a base for the stock and locomotives for its Jacobite service. The Transport for Wales depot at Machynlleth has also been used previously for the Cambrian trains, but due to the line having the new ETCS system fitted which presently isn't compatible with steam locos the services had to cease.
  Rolling stock
  The company owns and operates a fleet of diesel locomotives, which are primarily used to haul charter trains, but have also been hired to other railway operators. The fleet is mainly composed of Class 37 and Class 47 locomotives, but also includes Class 57 locomotives, including the prototype passenger locomotive 57601.
  Several Class 37 locomotives were purchased from Ian Riley Engineering, which ceased its spot-hire operations in mid-2004. In 2005, WCR won the contract to haul The Royal Scotsman luxury train. As a result, its two operational Class 37 locomotives and a Class 47 were repainted into a revised maroon livery, officially known as Royal Scotsman Claret, based on that of the Royal Scotsman carriages. In late 2005, WCR sold its two operational Class 37 locomotives (nos. 37197 and 37261) to Direct Rail Services, and received four Class 33 locomotives in exchange. As of 2011, WCR started investing in more Class 57 locomotives, bought from Advenza Freight, Harry Needle Railroad Company, Freightliner and Porterbrook.
