Arosa Ge 4/4: Safety Systems?

The usual key board maps (ctrl-enter and shift-enter) don't seem to work, and I can't find any button or switch in the cab. And the manual unhelpfully says that they are off by default, and to enable them go to the "Options > Settings menu"??

 

They are on by default. I think it's the only loco where this is the case.

 

They are off by default.

The button to enable zsi is below the desk console on the left side. After turning it on, i shut down the loco quickly with the master key just in case. Then when activating the cab it works.

 

Is that the button labeled "Dead Man's Pedal Cutout?"

 

Yes

 

So decided to double check by doing a chur - arosa run. Didn't touch anything expect the controls needed to move and the zsi-90 worked fine without activating anything. Got two green beeps along the way and a yellow one at arosa. After that I checked the dead man's switch, it seems it's only purpose is preventing you to leave your seat because it goes into an emergency brake if you do that.

 

Yep that’s the way the system works. Dead mans handle is different from zsi system.

 

Ah ok, i thought rivet put both systems on that switch. On the real locomotive its the "talfahrtschalter", which has nothing to do with zsi, nor deadmans pedal.

Thanks for solving.

 

"Valley driving switch"?

 

Basicly this would more fit into the thread where somebody asked about the different stages of the vacuum pump. But anyway:

Not sure if TSW is capable of simulating the change of atmospheric pressure in a route (since its not a flight simulator ). People playing flight sim or do real aviation know this sure: The air is getting thinner the higher up you go, so you have to set your alt gauge according the airports atmospheric pressure before landing at your destination. This topic is related to weather, temperature, climate etc.

What does it have to do with Railroading (tsw)?

The RhB Network drives steep gradients in a "short" amount of time. This affects the brake system of the train. When making a "Talfahrt", means going from a high location like st.moritz down to chur, the atmospheric air pressure gets higher, which leads to stronger brake behavior up to situations where the vacuum pump couldnt release the brakes anymore.

So with that switch actually the loco will seal an additional reservoir, which creates a higher vacuum proportional to the raising atmospheric air pressure. So the procedure is in St.Moritz you set this swicht into "talfahrt", and in chur you turn it back to "normal".

Here is a engineering description in german:

 

I dont mind rivet put the "dead man" pedal there, i remember matt sayd on a stream different airtemperatures are simulated, not sure its also for the pressure.

Actually you can change the stages of the vacuum pump, and you will notice on stage 3 its created faster.

 

Well, I now have my weekend's German homework!

That makes perfect sense- but one wonders why the Swiss didn't just use air brakes rather than be subject to the vicissitudes of Alpine atmospheric pressure?
