How's this for a piece of logic, Mr Disgusted of Mauldeth Road: That train is the 0831 from Crewe. Mauldeth Road is the last stop before Piccadilly. On the presumption that the 0930 cut off applies to all station stops for that train, everyone travelling on it will be paying peak fares except those joining at the last stop. By moving that last timing forward by 1 minute, the complete journey becomes subject to peak fares. That would make it simpler both on train and on arrival at Piccadilly to ascertain if passengers had the correct (Anytime) ticket instead of having to allow for one small group of passengers holding Off-Peak tickets.There are actually posters going up saying that, for customers from Mauldeth Road, off-peak tickets will no longer be valid on the 0929 service. Nobody has noticed my rear end. Can I infer from your explanation, Indigo2, that the WTT will schedule the train in exactly the same way as the day's subsequent xx:30 departures? If so, there can be absolutely no justification for this alteration in the PTT - and I fully intend to let them know how thoroughly disgusted I am.
I know moving from Peak to Off-Peak during a journey happens a lot elsewhere - I take advantage of Off-Peak shoulder timings myself on certain journeys - but it's a possibility. Or am I crediting Northern with too much intelligence?
