A Trello card has just been put up for Brake System Selector Switches

I am hoping as well as air brake types, that it would also include air or vacuum choice for dual braked locos.

Air Goods / Air Passenger / Light Engine / Vacuum Braked / Vacuum Unbraked

This is another request for something already discussed - A Selector Switch.

If coders could find a solution to the selector switch problem it would open up many possibilities.

Electric locomotive selectors

Thanks for doing that for us!

Hello.

I would add it here to the "Options within Eng and Wag files" section.
To do this, the vehicle coupling should first be brought to the MSTS standard. In MSTS, there were several types of car couplings.
1.Chain.
2. Automatic
3. Bar.
During the game, only vehicles of the same type can be connected. The Bar type was particularly interesting. This meant a rigid relationship. This type could not be disconnected in the window that can be activated with the F9 key. You knew the CouplingUniqueType ( "X" ) modifier. With this, for example, the Automatic type could be made unique. The CouplingUniqueType ("scharfenberg") coupling cannot be connected to the American system switch, even though both are Automatic.
The code snippet below is for the FLIRT locomotive. The first entry is for the vehicle switch at the rear of the vehicle. This means a rigid unbreakable connection. The second applies to the vehicle switch on the front of the vehicle, which is Automatic and unique.

	Coupling (
		Type ( Bar )
		Spring (
			Stiffness ( 1E7N/m 1E7N/m )
			Damping ( 2E6N/m/s 2E6N/m/s )
			Break ( 3E7N 3E7N )
			r0 ( 3cm 13cm )
		)
		CouplingHasRigidConnection ( 1 )
	)
	Coupling (
		Type ( Automatic )
		Spring (
			Stiffness ( 1E7N/m 1E7N/m )
			Damping ( 2E6N/m/s 2E6N/m/s )
			Break ( 1.7E7N 1.7E7N )
			r0 ( 18cm 28cm )
		)
		CouplingUniqueType ( "FLIRT" )
		CouplingHasRigidConnection ( 1 )
		Velocity ( 1.4m/s )
	)

The code snippet below is for the DESIRO power train. The first entry is for the vehicle switch at the rear of the vehicle. This means a rigid unbreakable connection. The second applies to the vehicle switch on the front of the vehicle, which is Automatic and unique.

	Coupling (
		Type ( Bar )
		Spring (
			Stiffness ( 1E7N/m 1E7N/m )
			Damping ( 2E6N/m/s 2E6N/m/s )
			Break ( 1E7N 1E7N )
			r0 ( 10cm 1E9m )
		)
		CouplingHasRigidConnection ( 1 )
		Velocity ( 0.1m/s )
	)
	Coupling (
		Type ( Automatic )
		Spring (
			Stiffness ( 1E7N/m 1E7N/m )
			Damping ( 2E6N/m/s 2E6N/m/s )
			Break ( 1.7E7N 1.7E7N )
			r0 ( 10cm 1E9m )
		)
		CouplingUniqueType ( "Desiro" )
		CouplingHasRigidConnection ( 1 )
		Velocity ( 0.1m/s )
	)

The two vehicles have a Scharfenbergkupplung, but their height is different, so they cannot be connected in reality. You can't connect in MSTS either. Here, however, yes.
It's interesting that the developers try to follow reality in some respects, and sometimes they don't when it comes to spectacular things.

Hi.
The idea comes from me. Actually, if I had normal programming skills and could see the operation of the entire EP brake system, which I can only see so far, I probably would have already written it. But I trust that it will be realized one day.
Sincerely,
Marci

This is good news. The development can move a little further.
The Open Rails project has possibilities for this, as evidenced by some of its local (national) versions.
