I have a recess in my basement wall under the fireplace that is 46-1/2" across. I want to use this area for a 22" radius helix as a way to change levels on my new layout. I'm working in HO. Is this radius generous enough to use for this purpose with reliable operation? I operate mostly diesel units but have a 2-8-2 Mikado and an Amtrak pasenger train.I figure it will be okay for the diesels, but I'm not sure about the Mike and the passenger train. I run this equipment now on 22" radius curves with no problems. Also my longest freight is 25 cars. I anticipate a rise of about 1-1/2%. <br /> <br />Opinions, please!
