When i boarded one SBS MB0405 DM, the rego was 5XX. I forgot the rego. The three buttons D,N,R had VOITH printed on the side. But that bus wasn't a voith 0405. It was ZF.. Then why did it have VOITH buttons for the gear changing??
I don't think the SBST O.405s ever had ZF gearboxes. They are mostly MB and some are fitted with Voith.
