Sorry, there was a gross inaccuracy in my post, I don't know what I was thinking about. Not enough timekeeping on my part over the festive period maybe!
I meant 1737 and 1743, I'm pretty certain those are the actual departure times rather than that what RTT says. They both still go from 16 as far as I can see.
My point about operational convenience is that, whatever the arrangement is for, on a daily basis it evidently isn't in the interests of the confused passengers who end up in the wrong part of Scotland. The Inverness train is parked locked at the rear of the platform for up to half an hour while regulars in the know (mostly Kirkcaldy commuters) stand around the doors, which only encourages the more casual Aberdeen passenger to believe that this may be their train. Quite rightly the crew only open the doors at the point that the front train pulls out, but by that time the damage is done.
Anyway, we've gone off topic, and I'm not excusing the daftness that led to the original post, but the railway can be a confusing place to those unfamilar with it.
