I would suggest it is the other way round. The ecclesbourne valley service is timed to meet the EMT serivce. The EMT service to/from Duffield is timed in turn to connect with the London service...
Agreed. The Ecclesbourne Railway have chosen to connect with EMT, and it works well.
Whenever I've travelled with Peak Rail, they have chosen not to connect with EMT. The staff admitted it to me, and claimed the timetable could not be changed because it would cost too much to re-print them. I doubt that made commercial sense. The train was almost empty, because it did not connect into EMT, and the next EMT train was 1 hour 58 minutes later (every 2 hours on Sunday).
I was very impressed with my visit to the Ecclesbourne Railway, and plan to go again some time (with my bike).
I doubt I would travel on Peak Rail again.... unless they extend
and connect. Otherwise, is there any point? From Bakewell, we have to cycle at least part of the way towards Matlock, and is there any benefit to taking a train for a short distance that misses the connection, compared to continuing to cycle a little bit longer, and guaranteeing making the connection? Well, no, not at all. I want to support preserved railways but sometimes they make travel with them so unattractive it becomes unviable.
