You don't even have to read any forum, take a look at Caledonian Sleepers own twitter feed, which is full of delay/cancellations/trains terminating short, not great for something that's being called a hotel on rails, seems an issue to be every other day, a lot of which is getting the sleeper ready from Wembley depot. Yesterday's issue with the southbound lowland, turfing passengers out at Acton Bridge, not a great station to cancel any service there with it being a rural station with a few trains a day[luckily enough there was one due 07.32], i don't know whether the lowland could have carried on in service to Crewe, since it went ECS movement there.
