Fixing car weights

[bpetit]

How would I go about this? There's a couple of things in the bin I don't quite understand like Mass or MaxPercentageofVehicleWeight. Plus I think the brakes are wrong.

Could someone elaborate on this matter?

Theere were a few threads in the forum. Search for "physics".

Thanks Chacal.

Using RS tools which I now love. I've edited the two default boxcars to have 40 tons empty and 91.5 loaded. Based on real life figures from a 60ft boxcar.


Anyone want to be my guinea pig?

I give them a go.

Ok, and don't forget to load them as well. Place in the Kuju Rollingstock Boxcar Default, Def2.

My report is based on taking RSC GP9 and pulling 12 loaded and unloaded box cars out of Minturn up the hill. The loaded bax car for sure was heavier to get rolling, nicely so, however on the grade in notch eight both the loaded and unloaded ones pulled at the same speed. This was run at a top speed of 35 and ground down to 18.5 mph.

Was the GP9 already hooked up to the boxcars at the start of the scenario, or did you have to couple them ?

Gradient?

[buzz456]

About 1 foot for each 150. What's that?

[bpetit]

I mean the grade you know like 1.1%, 2.2%, 3% and so forth.

Also on which route are you on?

1 in 150 equals about .6 percent. Minturn is on Tennessee Pass.

[buzz456]

I had to couple up to them in both cases.

Dont' forget about this

For true physics cars have to be already coupled to engine, otherwise they are inaccurate.

[buzz456]

OK gang, now having read Bob's post I will go back tonight when I get home and run this over again and post the results.

Also so you know, all NERW rolling stock has adjusted weights for loaded and unloaded. I did it to them long ago.
