1) Does that mean Alderley Edge services off-peak are empty most of the time? I've rarely travelled on that route (last time was on the old electric trains - similar to diesel class 101 but im unsure of the class number! You couldn't walk through to the next carriage)
Yes. There's rarely more than about 40 people on them off-peak and they use a 323 with up to 280 seats, even at peak times that service could cope with a 2 car 142.
2) What are these changes that have occured to the Windermere service in the new timetable?
The change was made in Dec 07. Prior to that the standard pattern on the Bolton corridor was:
Buxton to Blackpool NT (hourly 2 or 4 car 150/156 operated)
Man Airport to Blackpool TPE (hourly 185 operated)
Man Airport to Lancaster TPE (hourly 185 operated- final destination alternated between Barrow and Windermere)
Man Piccadilly to Carlisle VT (2 hourly 22x operated- final destination alternated between Glasgow and Edinburgh.)
The pattern is now:
Man Victoria to Blackpool NT (hourly 142/150/153/156/180 operated)
Hazel Grove to Preston NT (hourly 142/150/156 operated)
Man Airport to Blackpool TPE (hourly 185 operated)
Man Airport to Lancaster TPE (hourly 185 operated - final destination alternates between Barrow and Glasgow or Edinburgh)
There were and still are some off-pattern services particularly at busy times but the above is the standard pattern
