There seem to be a lot of uncompletable services on the high speed section of this route. 1J26 starting at 11:10 1J38 starting at 14:10 1J42 starting at 15:10 everytime you get blocked by a train that refuses to leave Ashford so your platform is blocked. I've tried being early, on time & being late. So much for the automatic timetable checker
I just ran 1J26 and only red signal I encountered was at the far end of the platform at Ashford. This should be expected since the end of run always face a red signal.
I tried 1J42, 15:10 from St Pancras a moment ago, and it completed for me. I was pretty much on time the whole journey and arrived 40 seconds early into Ashford. About 2,5 miles out, at 15:46, I met a northbound train. Maybe the one in the way for you?
Yes i left ebbsfleet 1 minute early it seems it must lock the path to Ashford blocking the route for the northbound train to cross the tracks outside the station. I'm gonna try it again and leave ebsfleet ontime or even leave a minute late
