Another Flatcar Problem

[TheKman]

I got another TOFC car out the door. This one is a RTTX Twin-45. It's appearance is much better than the F89J I've done.

These 89' flats are not my friend I tell ya.

Started testing in the afternoon yesterday and didn't get far. The car operates on straight sections just fine. But when it goes into a curve, there's hardly any bogey rotation. This causes the car to climb the rails and tip over. Two frames of mind here. It's a bogey problem within the bogey blueprint, or the data I entered for Collision Centre Y in the wagon blueprint is wrong. Might also be the Collison length data is off as well.

When computing Collision Centre Y: This is a loaded flat with two trailers. This is the formula listed in the docs. "To calculate this value: Take the height of Vehicle Subtract the driving wheel diameter from it Halve the result Then add the driving wheel diameter back in Enter the value obtained"

Pretty simple and I understand it. What I'm curious about is the height of the car. Do I include the trailers? I computed data as if it had no load. If it's collision length I'll just have to play with it and see it fixes things.

.xml enclosed.

Thanks

Problem solved. No issue with the car or the blueprints. The curve it derails on was too tight. (Just like on model Railroads!!) The testing ground has been the 1869 Cheyenne route. There are many tight curves within the yard where I've been testing. Good testing ground in that spot for the shorter length cars. I can still use this route, just start testing on the mainline with longer cars.

The car does need some fine tuning. Couplers sit a wee bit too high, the wheels of my trailers are slightly buried in the deck of the flatcar and my end steps are floating in the air a bit, The TTX yellow still needs to be a bit darker.
