Radius calculation | O Gauge Railroading On Line Forum

If I have 1 curve piece of track. Assume I have no other piece to compare. How do I figure out the radius? I have a bunch of Ross track that is not marked, maybe there is a template I can use? Thanks.

If you have a bunch of track, I would suggest organizing all the curves in like bunches, then putting them together to make a half circle, then measure it. You probably only have a couple sizes.
Plan B - make a template of one, make copies and put them together. Forget the rocket science. Guys who get hung up on getting too technical never build anything. It's toy trains. Get your hands dirty and put some track together. Cheers.

Neat calculator Ed.

Don't forget to do your measurements on the center rail. The inside rail will give you some odd looking results.
