Dear folks,

I am in the final stages of activity development using amongst other the TOFC cars out of the BNSF Mainline set. When running on the BNSF transcon, direction Barstow towards San Bernadino, I get a broken coupler on the crossover just before the beginning of the 55 mph restriction out of Oroville. I even tried to cross the crossover at 10 mph with no effect. My current coupler settings are
CODE

Coupling (
 Type ( Automatic )
 Spring (
     Stiffness ( 1.2e6N/m 4.8e6N/m )
     Damping ( 5.6e6N/m/s 5.6e6N/m/s )
     Break ( 1.8e7N 1.8e7N )
     r0 ( 2cm 3cm )

 )
 Velocity ( 0.1m/s )
    )


Can anyone elaborate on whether these are correct or how I could change them to avoid the broken couplers?

Thanks in advance!

There has been so much written on setting up this section of the eng/wag file. A quick and dirty way to stop the problem is change the 'break' value to at least 3. So the line would read "Break (3.0e7N 3.0e7N)" I myself use a vale of 4.5, no scientific reason, it just cuts way down on breaks when crossing node points.

Sebastian,

Try the settings in my "White Paper" found in the physics forum. They should solve your broken coupler problem and still give good "slack" action to your train. Part 3 ( and addendum ) have the values.

The reason I was asking it here was first of all they are Dekosoft products. Then I haven't been following the ongoing discussion closely, so I am not aware of what has been going on.

Anyhow, I will have a look at it!
