Currently the Newcastle turnarounds are around 10 minutes for the Airport services and around 35 minutes for the Liverpools. The booked Newcastle platforms shown on RTT for May to Dec would leave the Liverpools' turnarounds unchanged, but extend the Airports' by an hour, to around 70 minutes.
Is the plan now to interwork the Liverpool and Airport diagrams at Newcastle? That would even up the turnaround times, with around 55 - 60 minutes between an arrival from the Airport and a departure to Liverpool, and around 50 minutes between an arrival from Liverpool and a departure to the Airport. But any 802s introduced before December would have to work both routes.
No, they are due to be separate diagrams. The Liverpool’s are booked into bay platforms at Newcastle. The airports arrive on 2 or 3 and then shunt into Forth Banks sidings and then back to take up their departure for Airport.
