RE: ANW and ABW double decker influx - where next?
It isn't confirmed where the Winsford B7s displaced by the Sapphire Enviros are going yet, is it not a possibility they could go to Bangor to replace the Lowlanders? Bear in mind the reason they were transferred from Midlands in the first place was because Low Height stock was required, and the 4100 B7s are the oldest in the fleet that are low height, of course all London stock being full height.
