The use of this locomotive and wagons does result in the springy coupler effect, whereby when manipulating the brakes you can jolt forward by as much as 3-4 mph. Please be mindful of this when approaching signals at danger.
On arrival at Newton Abbot and from the point you first uncouple the wagons, you then have around 11 minutes to complete all shunting manoeuvres in order to clear the platform for the next passenger service. This can be completed fairly comfortably, you don't really need to go any faster than 30mph during this operation. Because of these shunting operations, the driver cannot be at both ends, that means that for the final part of the scenario the driver will be in the rear cab.
Please remember that the maximum speed of your train is 60mph and as this is a freight scenario based on real operations, if you prefer fast end to end passenger runs then this scenario might not be for you!
