The question is, if one company were to quit running the X38, which would it be?
From an outsider perspective (someone who doesn't particularly know the ins and outs of management of each company) it seems like Trent would be the more likely to pull out.
Arriva is a national corporation, so surely they would have more resources and funds to keep running the service? Trent have had issues regarding bus driver shortages, maintenance backlogs and, although not exclusive to them, rising fuel prices. Though, that being said, I am not as invested in the Arriva scene or use their services often at all, so what is actually happening with them I have no idea. Didn't they cease providing services in the Warrington area?
From a user perspective and as someone who has the (mis)fortune in having to go to Burton frequently, it would be a shame to see Trent go, as I for one much prefer their buses. Sure, the branding aspect of the route is nice to look at and all, but 98% of the time I find the drivers way less miserable and the buses themselves, regardless if it's a B7 or a Solo, always cleaner. Something about the interior of Arriva buses makes me feel unpleasant.
