Lionel HO gauge Challenger

Hello,

Is anyone operating the 4-6-6-4 steam locomotive on 18 inch radius track?

I would like to hear how it is operating on the 18 inch radius track. Are there derailments or uncouplings?

Thanks
Ron

I didn’t know it was released yet, but according to http://www.athearn.com/home2.html it will operate on 18", all drivers & tender wheels pick up current. I thought I saw a MSP of over $500.00
