Yes 507011 still stabled in the same place it has been for 2 months now with 001 in front of it and a 6 car set stabled alongside platform 1 in the station.
The six-car set is 507010 and 029, which finished there last night after working the 21.21 from Hunts Cross. Other units and their locations are: 507003 in the sidings at New Brighton, 507007 at Birkenhead North, 507015 and 018 at Kirkdale, 507016 and 017 in the sidings at West Kirby and 507023 in platform 2 at New Brighton.
With a bit of luck, 023's location means it will be on the New Brighton line tomorrow.
Logically, 001 would be used to replace 015 when the latter is pulled from service in the coming days, then 011 and 015 would move to Birkenhead North for decommissioning, but we'll see if it plays out as such.
