Must say from a North of Four Lane Ends view I'd say

37: Not busy, but there's people on - very quiet by Cramlington
38: Don't see it, no comment
353: Lightly loaded, especially after butchering the frequency in half
354: Dead
62: Very lightly loaded, outside peaks
63: Don't see it, no comment
355/356: Generally well loaded at Western side, dead around Monkseaton
X7/X8: Picked up the 52/54/555/X63 loads from Quorum to Metro/Newcastle, Metro loads being people connecting at Haymarket since they butched the Four Lane Ends to Quorum frequency so it's borderline unusable
X63: Lightly loaded, outside peaks.
