Jet Train

[rrroberttt]

Has anyone gotten the NALW_Jettrain.zip in the file library to work in OR ?

You need MSTS to run OR. It should work fine unless you somehow made a consist incorrectly or did screwed something up.

I guess it won't move one inch in OR since OR thinks it is way too light and has way too much power, hence you get endless wheelslip even if you put the throttle on 1%.

Maybe it helps to increase the adheasion values up into astronomical spheres -- values of twenty or thirty should give it the right grip. If OR does compute the adheasion values at all, that is.

You can always use the simple, sticky adhesion model by pressing Ctrl+Alt+X

You are not correct, OR computes adhesion very precisely - much more accurately than MSTS. Please ask if you you want to know how OR operates, we'd be happy to share that information. The exact OR equations are: Output AxleForce (the force transmitted to the rail) is result of slip characteristics so you need to compute the wheelslip. Firstly the dynamic force on axle is computed as: DynamicForce = DriveForce - BrakeForce - FrictionForce - AxleForce.

This dynamic force causes acceleration (positive or negaive) of the axle and so the wheelslip is changing. With wheelslip the AxleForce changes and results in lower DynamicForce. This is solved easily using a differential equation solver for these parameters in real time.

In my case, what is happening is, that after the brake have been released, applying throttle only give a knocking sound. The wheels are not slipping, the train just does not respond to the throttle key.

[longiron]

Based on your symptoms, my assumption is that the throttle configuration is not supported by OR - these are usually un-notched throttle definitions. You can confirm this in the F5 HUD not showing any tractive force.

@Longiron:

Thank you.

The trottle of the Jet Train doesn't want to go up and stay always at 0 %.

In the ENG files you have EngineControllers configuration at line 874

EngineControllers (
Throttle ( 0 1 0.025 0
NumNotches ( 0 )
)

You have just to change the value of NumNotches ( 0 ) to NumNotches ( 9 ) and add 9 lines like this.

Your new EngineControllers

EngineControllers (
Throttle ( 0 1 0.025 0
NumNotches ( 9
Notch ( 0 0 Dummy )
Notch ( 0.125 0 Dummy )
Notch ( 0.25 0 Dummy )
Notch ( 0.375 0 Dummy )
Notch ( 0.5 0 Dummy )
Notch ( 0.625 0 Dummy )
Notch ( 0.75 0 Dummy )
Notch ( 0.875 0 Dummy )
Notch ( 1 0 Dummy )
)
)


Payattention to don't forget the parenthesis at the end.
Now your Jet Train worl fine in OR. But it is highly polluting. It fume like a good old Alco diesel.

Have a nice day!

@Nicober:

Thanks for that. I will try it later.
