Sound when certain buses move off

Postby Perth Jaywalker » Fri Feb 24, 2017 5:44 pm

Anyone else notice that on some buses, there's a horn-like (but not loud) sound when it moves off from standstill?

Last time I noticed this was today, on TP 2313. I think it happens on all similar buses (but I'm no make/model expert).

On the volvos the sound is the park brake releasing Perth jaywalker.

It is the maxi brake being released, seems to be more noticeable on Volvos.
