Owing to the still mythical DD's on this route I finally called Arriva. Guy there was very helpful and explained the 78 is getting the buses from the 38 route when they get new buses. Delay of 6-8 weeks from now owing to late deliveries and technical mods.
I really don't understand this. The 38 route has just got new buses - at least not longer than a year or so ago. It was the first route to get new buses to replace the bendies that Boris promised to have withdrawn.
I thought we were living in an age of austerity! So where has the money come from to ply the 38 bus route with even newer vehicles that it blatently doesn't need?
Is this the reason why public transport tickets go up every year? Because London's 'flagship' bus routes - of which 38 is one - can't possibly go without having new buses every few years?
