Presume 769421/52 (ie the cavalry from TfW) are still not yet ready, and 769431 at Brodies is still having its holes filled at Brodies. It's about time that Northern pulled the plug on this lot...........are Porterbrook now actually paying Northern to use these units as opposed to the other way round?Yep, it got to the point around half 10 this morning that there was only one working unit left, and Network Rail have stated that when it's down to one it has to be pulled from service.
