A while back, a friend of mine gave me his family's collection of HO Tyco locomotives and cars, with a few Lionel ones thrown in, and a huge amount of brass and steel(?) Tyco track. I also have a Life-Like Union Pacific starter set, an unknown Amtrak Genesis passenger set, and an unknown Cheesie F3.
1. Has anyone written a book or done a thread about fixing or upgrading these engines so they run well?
2. Would it be possible (or reasonable) to upgrade the motors and add sound, or just sell the lot and buy new HO?
3. How do you clean brass track?
