Very nice pack, well designed interior cab with some news controls and a wonderful engine sound! Currently am playing a nice pack for Class 67 from Roussillon Aero Simulation, is worth a look:

But, in the Manual there is no explanation about how "Locomotive Mode Selector (#20, page 6)" works. Is it functional? I notice to the left of cabin a "Speed Control up/down key" that does not work yet, and may be related to speedometer limit settings (another type of cruise control?).
Thanks.

I'm playing a scenario pack with a DB Schenker Class 67 (red livery)
and it explains why in the shot I posted before the DBS is running in a tipical UK signaled track...
