In terms of the StreetDeck, I would say that it's a vehicle aimed at routes akin to the following criteria:

- Urban Routes such as ANE's 308, GNE's 21.

- Developing and growing routes such as GNE's X21 bearing in mind that it currently has a layover at Bishop Auckland.

Another route in which it would be justified getting Streetdecks but already has E400s would be the 7 due to the variable load factors. The same could also go for the 4x decker boards on the Red Kite which also fall under the same criteria. Not suggesting upgrades on the above routes but just highlighting examples.

However, where a route is more demanding but stable and profitable, then a slightly more heavy duty vehicle could be warranted. The X15 is a proven route and warrants vehicles fit for purpose.
