Hello Weter

Unfortunately, the OR only knows one coupler. MSTS was better in this regard.
Some parameters are included in the Default.wag file.

Really?
What a loss :(
There are steam engines, or fixed formation MUs, that use 2 types of couplers.
Passenger cars use same couplers as freight, but with more short spring, movement.

Unfortunately yes. Although I have a little question mark in me. I read in one of the threads here before.
It would be good because the vehicles could be set up more accurately.

	Coupling (
		Type ( Chain )
		Spring (
			Stiffness ( 1E7N/m 1E6N/m )
			Damping ( 1E6N/m/s 2E6N/m/s )
			Break ( 1.1E8N 5E8N )
			r0 ( 5cm 8cm )
		)
		CouplingHasRigidConnection (  )
		Velocity ( 0.1m/s )
	)
	Coupling (
		Type ( Bar )
		Spring (
			Stiffness ( 1E7N/m 1E6N/m )
			Damping ( 1E6N/m/s 2E6N/m/s )
			Break ( 1.1E8N 5E8N )
			r0 ( 0cm 20cm )
		)
		CouplingUniqueType ( "Steam" )
		CouplingHasRigidConnection ( 1 )
		Velocity ( 0.1m/s )
	) 

Unfortunately yes. Although I have a little question mark in me. I read in one of the threads here before.

In the code snippet above, the first coupling is in the rear of the vehicle because it is an editorial of a steam locomotive [Type (Tender)]. The second coupler is the first coupler of the tender, which cannot be decomposed. At least it should be.
The CouplingUniqueType () entry is used by the German EngMex program. I took it from there.

So, (coming back to this thread's question), can modelers use include files to determine different coupler types for the same vehicle?

At least, I see no sense to use both (native and include) blocks simultaneously: if use include, then original block should be deleted or commented-out from the *.eng-file.

I will delete or comment. The latter is usually when something is new to me. At that time, I also write why it was commented on and where I can find the right parameters.
If there is more than one type, the one with the lowest track number is commented on, the others are simply deleted.

Can someone please clarify, does OR only use one coupler?

Also, the default.wag file is mentioned. Is this used by OR?

I read this before in another thread. It could even be true.

Hi Folks,

As a steam loco builder - yeah - I tested this before and as far as I can tell it only uses one coupler block of code.

Also keep in mind - for precedence - if you put an "OpenRails" directory in your model's hierarchy to store things like your ENG/WAG files - ORTS will read and use that information first - overriding anything in the root directory.

Regards,
Scott

Which coupler entry is used, the first or the second?

Hi David,

I did my testing a couple years ago - I think it was the second - as a result - my work only includes a single coupler block now.

Comment ( ##### COUPLER ##### )	
Coupling (
		Spring (
			Stiffness ( 1e4N/m 4.5e6N/m )
			Break ( 1200kN 1200kN )
			r0 ( 5cm 5cm )
		)
		CouplingHasRigidConnection ( 1 ) 
	)

What I've noticed is that OpenRails does only use one coupler, HOWEVER you still want to include two couplers as which coupler is used depends on the orientation of the rail vehicle. If you have just one coupler set up things will seem to work fine until you flip the facing of the locomotive or train car, at which point a default coupler is applied (the default coupler settings are probably not something you want to use.)

Hello.

I made a video. The OR does not know the different types of car couplings, otherwise the car connected to the load could not be uncoupled [Type (Bar)].
There was no such thing in MSTS. The train (stock) could not be dismantled.
