The scenario editor we have at the moment is pretty plain and simple. We hardly have any freedom in what we want to do as our options are very limited. A way to combat this is by introducing something that TSxx has already had for quite some time. A consist editor. The Scenario Planner right now only lets you choose between pre-made formations that are no different to the ones you have in the Timetable Mode (if at all; as some are missing). A consist editor would effectively let you build your own train (formation) more or less to your liking. Screenshot from TSC: With Locos gaining independence from Route DLCs this would be the perfect opportunity to do so. Especially the 101/187/185/Class 66/... presents a lot of opportunities to couple it with a variety of waggons such as the Dostos or even couple it with a BR425 to bring it to the maintenance. While it wouldnt make the Scenario Planner perfect, it would drastically improve it in my opinion and give the Scenario Planner some much needed freedom.
