Creating timetables in the official TSW 4 editor is very rewarding, but challenging to get right. To aid other timetable creators, I've uploaded the full uncooked plugin of my East Coastway timetable, so you can see how I've done it. You can download it here. I hope someone finds it helpful!
This will be very helpful - now DTG need to supply a "demo" loco as uncooked plugin. (RailWorks actually came with a step-by-step tutorial how to model and blueprint a simple loco.)
