It is and we're pleased to supply information of interest, to the point where it becomes commercially sensitive, so I trust people will understand that there will be questions which we won't be able to answer here.
There is one B7L due from EC, and it is not one of the ones we previously sent them! As I understand there is only the 1 surplus.
I'n not sure who the question about the 51/02 vehicles refers to, but we certainly don't have any general plans to replace such vehicles at BoS. Clearly there are some non DDA Tridents that will need to be replaced. It is always possible that some single deckers could be displaced by cascades, either for disposal or onward cascade, but there is no great urgency to replace DDA single deckers. There is no final plan for cascades in or out of FSW yet, and those plans are never really that set anyway, as over the course of a year vehicle requirements across UK bus change as contracts are won or lost, and initiatives implemented that can reduce or increase fleet requirements, driven by a whole range of factors, a number of which are not even within our control.
The 21 will have to have something to replace the non DDA Tridents in use on it, and indeed the replacement of our non DDA Tridents in general is likely to lead to the reallocation of types across BoS. The B7Ls are broadly for the 21, allowing Tridents to be moved onto other lines to replace the Olympians and to release a few Tridents to First Kernow.
