Hi - I have a medium size N scale switching layout that hasn't seen any activity for about 2 years. It's has code 40 hand laid rail and hand built turnouts. Since its been dormant track needs cleaning. Looking for a track cleaning car for starters that might help get things going. Just wondering what you folks have used that actually works. Saw one on Amazon from Bachmann if anyone has comments on it (sorry not good at copying links):
