Several issues with the Scenario Planner: 1. If you place a train in Lewes it is heading to Brighton, not to Seaford 2. In Lewes the player train does not get a path direction Seaford, red light that does not clear 3. If you start for Seaford, the signal aspect is stop and remains stop 4. There is no unloaded aggregate train, for the services to Newhaven Aggregate Service
In response to number 4: There is only 1 train that gets loaded there each week and that's the Newhaven to Brentford, and it's on a Thursday, so while not available, they would need a different wagon type added to the game to replicate that service.
