I'm not really sure if GNE would purchase a few Astromegas for the TTX, I mean I've been on them before and they are indeed very comfortable and pretty luxurious (alright, that may be a bit of an exaggeration), but the Astromegas are classified as coaches, and I don't think GNE are likely to purchase a bunch of massive double deck coaches. When you think about it, it's not gonna look very good if that's soaring into Gateshead Interchange after coming off the motorway. Also, I don't believe they've ever purchased from Van Hool, and that would break their recent 'Wright, Scania, Mercedes and Optare' policy of only buying from them (that's excluding the Olympians and Tridents etc, I mean like recent purchases in the past few years). If they go for a double decker, I think they'll pick this;

(I know it's just all different variants of the Gemini 2, but I was thinking about the Tri-Axel one)
And if they decide to go for the coach option, one of these;

(I know it's a school bus, but it certainly does seem to be quite sturdy and powerful)

(The Eclipse Commuter can have standees when compared to the SchoolRun)
OR, they could just follow David Bowyer's suggestion, I must say that would be quite exhilerating to ride
