I don't quite understand why this many specific reasons for failure have been recorded. Sure, there's equipment failure, technical problems, etc. but then there's also "...a broken windscreen on the train." which surely falls under one of the earlier two? Then there's also: * a fault with the on-train signalling system. * a fault with the radio system between the driver and the signaller. * a fault with the signalling system. plus 2 more copies of all of the above with either "earlier on this train's journey" or "earlier today" appended. I mean, don't get me wrong, as a public transit nut I love all the information I can get, but over here in The Netherlands itd'be very rare for the automated voice to give any reason more detailed than "a defective train" or "disruption on the tracks" and I can't see why beancounters at ScotRail wouldn't have come to the same conclusion.
