Open Rails and 3DTS's 'Cab Forwards'

[seagoon]

Is there any way, at the present time, to "fix" the wheel-spinning of the rear set of driven wheels?

This is a nice steamer but is not very happy with Open Rails.

Hi Bruce,

I was playing around with the Cab Forwards on Donner a few weeks ago... I think the spinning is better with the latest releases of OR... I don't think the AI locos do it... When using for player consist - if you hit [Ctrl X] to stop the wheels from spinning when you start out I drove them for a while and the spinning didn't seem to start up again...

More than likely, it's an error in the .eng file that MSTS didn't notice, but OR does.

Since other articulated work fine, that might be the issue. You might want to check the weight parameters...

You might want to try the following if you are comfortable with editing .eng files. Be sure to back up before making any changes so you can go back if something goes wrong.

Here is a snippet of the rear engine file showing the 2 lines I changed.

Mass ( 242t )This Line was Mass ( 10t )

InertiaTensor ( Box (3.632m 2.2m 10.624m) )
Coupling (
Type ( Automatic )
Spring (

Adheasion ( 0.5 0.5 2 0)and this line was Adheasion ( 0.25 0.25 2 0)

AntiSlip ( 1 )


Another change you can try is making the mass the same on both engines, around 141t. This would bring the total engine mass to near the prototype.

There is some discussion on another forum in the

Not sure if I can mention the other forum here by name.

Feel free to refer to Elvas, UKTS, or any other site by name. What gets frowned on is bashing or proselytizing for other sites...

[seagoon]

Thanks for the tips, lads!
I'll try that .eng file adjustment and see how it goes.

Cheers!

Jeez! I had to look that up to see what it meant!

Donald, thank you.
It works perfectly.

And here I thought you Commonwealth guys learned proper English....

IIRC, wasn't there an MSTS bug that made AI steam drivers spin twice as fast or half as fast as player locos?

Hi Robert,

I think "bin" fixed that issue...

[rdamurphy]

Thanks, Scott. I really couldn't remember...
