In 2007, the Monday-to-Friday peak service was reduced slightly, with the introduction of a new route 332, which incidentally replaced the 316 between Cricklewood and Neasden, that route having been introduced to replace the same section of route 16 ten years earlier. Another change to vehicle type occurred in mid-2008, when Alexander Dennis Enviro 400 double-deckers were introduced. These buses were bought for the new contract on route 460, but were instead allocated to Cricklewood Garage, in order to compare their performance with the earlier batch bought for route 332 and hybrid versions due for trial.
