I'm sure this question has been answered in one form or another but I couldnt find it.

I'm about to start building my layout and i would like to use 22 radius for the tightest turns, will big 6 axle locomotives and 85' freight cars handle this without derailing or uncoupling? I only have 4 axle loco's and 50' cars so i can't test it out, but i would like to purchace a bigger loco and a few bigger cars assuming they will work on 22 radius.

any advice?
thanks

Welcome to the forum.

They could work, the big issue being clearance. This is an 85' auto rack on a 20" radius curve. You can see what happens when another train passes on a second, 18" radius track...



Here is a 4-8-8-4 Big Boy on the same 20" curve. They can make it with some questionable results, both operationally and aesthetically...

I use Code 83 atlas track, I use 18 and 22 in radius.

I have found that, for example, Walthers Part # 932-4859(TTX Auto trailer), Just loves to jump the track on me.

My modern loco stay on the track with no issues (Though I had to remove all my manual switchers and put undermounts in as the Locos would sometimes clip them coming out of turns.) I would suggest upgrading to 24 radius if you can, if you cannot, still buy them and use them for display until you can upgrade your track.
