Yeah still on modern buses, Neutral Bus Stop as its sometimes referred to. A feature to reduce fuel consumption. On a Voith it's engaged when you hear the notable and brief rev once the bus has stopped, with ZFs you often get the wining during idling. Back in first gear when the accelerator is pressed or the footbrake/handbrake both released.
