Ctc3 Cab Car - Why Constant Air Exhaust

I'm curious why, whenever the auto brake is applied from the CTC3 cab car, there is a constant air exhaust sound.
When a reduction is made, and brake applied, valves are closed and pressure maintained. This suggests an open valve, which doesn't make sense to me, based on how I understand brake systems.

 

I've read a while back in the forums that that just copied the brake sounds/mechanics from the f40 in peninsula corridor. So instead of it being a automatically lapped brake, it's acting as a self lapped brake. But don't actually know why it does that or it's related to it. Something we'll have to deal with for now.

 

If you want a temporary work around, turn off the ep brake circuit breaker above the windshield

 

Interesting. Ok, I'll try that.

 

Thanks. Does it affect how strong the brakes are or anything?

 

No not at all

 

It is a fault, you're correct the valve should not be open. I was not aware of that work-around paweuek good one, that will make driving them much more pleasant.

paweuek great find with that switch! thanks for letting us know

 

You're welcome
Sorry but that find is actually not mine. I couldn't find the original author but the credits are for him/her ;-)

I agree that this solution saves a lot of nerves and ears
