I would love to see a foster yeoman set up in the game. Maybe with the route being inside their quarry and one of their runs around the country. They operated Class 59s which are the EMD locos custom built for Yeoman based on the SD40-2 but made to meet BR design requirements and British Gauge bridges/tunnels. They also had an SW1001 for use in their quarry only. And a couple of blue class 08s. Seeing as the SW1001 and Class 59 are similar to two already modelled in game locos (The 59 is very similar to a 66 in design) it might not be too hard to implement. The class 08 is already in game. They also had special wagons made for their loads. I believe that Foster Yeoman is now part of "Aggregate Industries" but the 59s still exist and operate under various companies. A fascinating chapter in the History or railways in Britain, being the first private operator allowed to run on British Rail and to have an imported locomotive which they owned. Before they bought these, BR Locos and BR wagons were used. But the company deemed the locomotives too unreliable for their business reputation.
