That's fair enough I suppose. 

But having a heavy duty vehicle given the climate we're in on a newly established route (the extra X30 evening journeys) must be quite costly.

Saying that, it will most likely change going forward depending on how the new interworking patterns are devised (if evening journeys are fully run by Consett) and also what cascades will eventually replace the Citaros if Riverside keep the evening journeys.
