Looks like the Airport train is back, and hourly too - someone mentioned on the 331 thread that these can be 6-car and so can the Hazel Grove. Another load of seats out of Blackpool North per hour.Northern have updated some of their temporary timetables with effect from July 20th. They mostly look to involve Blackpool and Scarborough routes
Edit: it's not hourly but it's more than two-hourly. More like two every three hours.
