This scenario has only been tested on the Steam version of the Cornish Main Line route although it should work fine if you have bought the route directly from Just Trains.
At the start of the scenario the crossing gates at Truro are open. To make sure they are closed ready for departure, the method I use is to creep forward as soon as the scenario starts before stopping and opening the doors. It's entirely up to you how you choose to do it.
The Cornish Main Line by it's very nature is a fairly quiet route and you should therefore not expect to see busy traffic. This and other scenarios I have created for this route are merely a way of driving different traction on real timetabled services and in this case provides a great opportunity to drive this passenger service in challenging conditions.
