I was on the Caledonian Sleeper from Glasgow to Euston a couple of nights ago and it arrived in Euston 49 minutes early. (http://www.realtimetrains.co.uk/train/G90585/2013/01/23/advanced - link active until 29th January).
It looks like this was partly because it was on a revised (slower) schedule for engineering work but the engineering works either didn't happen or caused no delay.
The early arrival didn't cause me a problem (I woke up in my berth after we had arrived at Euston), but what if I'd been getting off at Watford Junction (where the train arrived 48 minutes early)? Would I have been woken up by the attendant nearly an hour early? That would seriously have hacked me off. Would I have been allowed to stay on the train and make my way back out to Watford Junction on my original ticket, ie arriving at roughly the originally scheduled time?
