I have two old Bouser engins, Big Boy and Challenger. What size should the corners be to allow easy use of the layout?

Thanks

Some of the old larger steam engines do not look right on r18. I had a set of passenger cars that could not turn on r18. If you do not have space for r22 you might want to try making something in between r22 and r18 with flex track. One of the biggest mistakes I made was putting an r15 cork screw up a hill in my lay out. It looks nice but has limited me to 2-6-2 and 0-8-0 steam locos or diesels. Also my cars are limited to nothing longer than a 50ft box. Most everything is 40ft or less.

Can anyone confirm R15, R22 says a 90 degree turn and the inches of the radius? As you suspect I am a newbie!!!!

Norm, Jenks, OK

R15 will be to tight for those locos. The lower the number the sharper the curve. My 2-6-2 can make it because the wheels are small and close together. The 0-8-0 just barely makes it, that also is a short wheelbase for and 0-8-0. The locos you have are just to long to make the R15 turn without derailing.

Not yet clear

I sort of understand but want to know for sure the bassis for the R and 22 designation in R22 terminology. I think the R is radius and 22 is inches of radius.
