I thought of an idea It is similar to Scenairo Planner, but instead of only being able to timetable 20 services, you can timetable an entire day, and have it on a route (lets say Great Western Express) and make it so you're able to allocate it to a custom livery, formation or official trains. For example: 1P01 - Class 166 GWG - 10:45 Hayes & Harlington to London Paddington Also make it able so that service can continue onto a reverse or another route, for example THEN: 1H01 - Class 166 GWG - 11:30 London Paddington to Hayes & Harlington Or set it so it can sit in Paddington for 4 minutes before next duty. I think this would be an excellent addition, I wonder what you all think to it!
