Just thinking out loud, now TSW have rightly decided to drop Gen 8 consoles moving forward (sorry Gen8 users) - I wonder if we can make some changes to drop the silly limit on the number of trains you can run on console in Scenario Planner? Currently it's limited to 20, and it's hard to build a customised detail service pattern especially on routes such as London to Brighton.
One thing I’d really like is the ability to manually select precisely which path your train will run along (Junctions, station platforms etc), with a proper preview of it. Currently, you can only select one of the options given which means you might have to compromise the journey you had in mind (for example, perhaps you want to stop at X station and miss all the others but this means you have to be routed onto the slow lines for a significant portion of the journey when you don’t want to be).
