I seem to remember being told by an elderly man at Church who has now unfortunately passed that Leeds to Skipton trains would pass what is now known as Shipley platform 3 and the signal protecting Shipley South Junction. The guard would then go into the other cab and sound the buzzer when the signal protecting the junction had showed an aspect clearing the train into platform 5, at which point the driver would reverse the train into platform 5.
Unfortunately, the addition of platforms 1 and 2 hasn’t been as transformational as it could have been, as people travelling from Baildon to Leeds or any other Wharfedale station to Apperley Bridge and Kirkstall Forge still have to wait 20-25 minutes for a train from Bradford Forster Square, seeing as Ilkley to Bradford trains arrive into Shipley one minute before a Skipton to Leeds train leaves, unless there is a Carlisle/Morecambe to Leeds train right behind it, in that case the connection is feasible.
I would say that Wharfedale line passengers being being able to connect onto a train going to destinations beyond Skipton has been incredibly useful.
