TTX isn't getting Streetdecks but rather Volvo B5TLs. Bodywork is unknown yet but if ordering from Wrightbus, it would certainly be well thought if they were to be Low Height as when they come to the end of their working lives, they could be allocated for routes where a full height decker may not fit under such as the X30.

TENs also very unlikely to receive an upgrade as they'll most likely be getting 3x from the TTX for the 'Tyne Valley Ten' (if that leaked timetable was right) plus a further 2x as spares for Hexham / Riverside and the last one remaining at Riverside if no spares are ordered for the TTX or getting transferred elsewhere.
