I have a New York Central HO Mogul 2-6-0 from Bachmann. Sadly, on one side some of the metal rods (piston rods?) cause a piece of plastic to pop off and hit the track, causing it to derail. Some suggestions would greatly be appreciated.
Thanks!

I received a Pacific Flyer HO 0-6-0 as a gift. On the instructions, it says it steams, but it does not appear the funnel has a steam fluid tank and the box does not say it steams. So basically my question is: does it steam?
Thanks!
