If it is a discipline issue rather than mechanical, then Arriva really need to nip this in the bud asap.Same here, I had 7627 on the X12 to Newcastle the other week and I thought it was dreadfully slow, we were overtaken by a Lolyne on the X21 between Pity Me and Chester Moor and ended up arriving Newcastle over 5 minutes late, we did stop at a fair few stops because the X21 was late and someone asking if it went near the Cricket Ground. Perhaps the driver was giving it a slow ride on that journey.
7619 was one of the Geminis I thought felt flat, but maybe it wasn't being made to try on that occasion.
I think there is a few other issues with timekeeping on the X12 with traffic being a major killer at times especially in Durham and Newcastle, Friday seems to be the worst day for it.
