radius of track
Posted by dbeaghley on Thursday, October 15, 2015 7:02 AM

I have a older railking challenger that ran just great on 036 fastrack.  I changed my curves to 048.  Now the challenger tender will derail on the curves.  How come.  I thought a larger radius would be better for a large engine.

Probably a bad track laying job. Is it still fastrack?

 yes it is.  The front wheels of the tender derails on the curves.  It runs fine on 036, but 048 the tender detrails.

Is it derailing in the same spot or different ones?

seems to be on the same spot on each side of the layout.  I tried switching track around, but the front wheels of the tender want to derail.  There is no problem with the tender harness hanging up, all wheels move freely.  On o36 radius the engine swings out and no problem.  O48 it looks like the connecting bar may be the problem.  I don't know what is going on.  Found the problem, the drawbar on the tender was bent down a little, I straighten it out and now the challenger and tender go around the curves perfect.  The drawbar was hanging up on the curves making the front wheels of the tender to lift up and derail.  Thank everybody for help.
