That's a lot of extra BSOG payment over a day since it's done by Kilometre. It wouldn't change reliability since you're just shifting vehicles around similar work. The spare bus situation wouldn't also work in reality, since you would have to replace the current spare deckers with other spare deckers.
What about swapping the ex tyne tees for em. How many are in corparate and maybe others from other depots. Maybe other spares and swap em with the omnidekkas.
