The Scenario Planner is a feature in Train Sim World 2 which serves as a means to create user-made scenarios for the game. It is similar to the 'Quick Drive' Feature in Dovetail Games' Train Simulator series, in that, with the option "Off The Rails" selected, any train installed can be used on any route in the game.
When creating a scenario, the user begins by selecting the origin station and destination station, then a train to run on the line; the length of the platform plays a part in selecting which trains can run from which station, as the game doesn't allow consists longer than the platform length to be selected.
