It was a huge sacrifice in space and money. But I did my new layout in 072 minimum outside and 060 minimum inside. And from on operational standpoint Im VERY glad I did. My 0-8-0 Linchief engines would slow down in corners on 036 and a little on 048. With many power drops and no track binding. They look 100% better and run 100% better on the larger radius curves. Same with my 2-6-2 Wabash and passenger set. Use the largest radius that you have room for. You wont regret it.
