Here is a rough service timetable for the West Somerset Railway. Some times may not be 100% correct, possibly a few minutes wrong in some places. I have attached the document AND linked the PDF encase one of them doesn't work. https://www.docdroid.net/4HliUVt/tsw-west-somerset-railway-service-mode-timetable.pdf
That's very sad that we, the users, are supposed to work on this... but thanks anyway NOTE: we are still waiting for NEC timetable and updated GWE updated timetable with platforms...
There is a chance some of the times are wrong by 1-2 minutes. But the majority should be 100% correct!
One small correction I found: Under Class 09 for the first run going towards Minehead, the time for Watchet should be 11:57 and not 10:57 as listed
Had a quick look, the 33 seems to just replace one of the 47s at random so no change to the timetable itself just the loco allocations so there is no point in updating this
