(15 Apr 2018, 12:34 am)L469 YVK wrote Just had a thought, but would it not be better for 6x to get ordered for the X18 (due to it being the busier of the 2x routes) then, cascade 7529-7533 on to the X15?

Unless plans are in the pipeline for the near future.

The PVR of the X15 is only 4, though. 7529-33 are only 3 and a half years old, and are doing perfectly well on the X18. Seems pointless to cascade them to the X15, which hasn't had new vehicles for as long as I can remember. 

Equally, I'd argue the X18 is only (a bit) busier during the summer months. Between Newcastle and Morpeth both routes are generally carrying pretty healthy loads. Even during the summer, the X15 is the quicker bus to Alnwick for tourists.
