So my idea for today is a LMS Jubilee operating railtours on everyone of TSW3's uk routes. If you guys want inspiration you could do the 07:13 London Paddington - Minehead to Reading aka the West Somerset Steam Express. Or maybe a diesel service from Bishop's Lydeard to Minehead as the last portion. This was just a small idea I had but I hope you like it.
This would mean rebuilding each timetable as they're pretty fixed in what they can and cannot layer in and out. An unfortunate development cul-de-sac
I think it should be standard on all UK routes and non UK routes if the rolling stock is available. Or throw in a scenario atleast.
