Rail Simulator is the next step in railway simulation. It allows the player to take on the role of a train driver and guide a number of contemporary and historical trains through several meticulously recreated routes in the UK, Germany and United States.
The demo features a Black 5 running out of Bath Green Park, heading to Radstock and provides tutorial dialogs to help you along the way. The demo cuts out after 10 mins or so and allows you to restart.
