BNSF Seattle - odd stock behaviour

[chrisreb]

Got the latest version of the route working. Doing the scenario Interbay -Tacoma run. The rather bizzare behaviour of the consist has caused derailments several times. Going along at say 20 mph and I bring the throttle back to zero from say notch one or two, after say 20 secs the consist lurhces and suddenly speed drops to 4 mph at the comes to a halt. The suddeness of the decelleration causes the derailments.

The hoppers are supplied with the route - is anyone else getting this?


EDIT: Using Hoppers from Sherman Hill eliminates the issue so the hoppers are the issue. Have e mailed Ian Allen re this as the hoppers must have some overly strong drag or braking force even when no braking applied.

I keep finding that is usually caused by brake and/or coupler settings. A lot of the time graduated release, proportional braking and triple valve are set to "eFalse" instead of "eTrue".
It can be quite a few other settings. Cylinder pressure for instance is quite often set at system pressure, when it should be something like 50 - 60 and match the pressure for maximum force.
There are a lot of things to miss in those .bins. Sometimes I miss something on the first time around.

Thanks _ ian said he will look at it. Definately the hoppers as other stock operates fine. 25 doen to zero in 3 secs is a little harsh
