Guys, I'm still kinda new with S scale so this may be a stupid question. I just received the new Lionel big book for 2018. I see that the new American Flyer Berkshires take a minimum curve of S36. BUT, I see they only have switches of R20 and R27. American Models doesn't have any switches larger than 27" radius. The same for MTH, if I remember correctly. Sooooo, how do you get your engines to switch tracks? I have run large engines in O scale thru smaller switches and they either just run thru very slow or bind or derail. Again, Soooooo, does anyone make a larger switch, like an S36, for hi-rail wheels?
