The ULEZ decker PVR at Riverside & Hexham (10/10A/10B/27/58/X10) is 37
So that would mean 2x out of 6001/49/50; 6336-37 and eventually 6377 giving a spare ratio of 1:7.4.
However, 6099 could also be moved from Percy Main and utilised to allow 6377 to carry out misc workings including the summer X11 runs (if they return).
