Ok, I'm a total newbie just getting into the hobby - HO scale.
I bought a table with MRC 280, layout, 6 switches, and assorted used goodies from someone on Craigslist.
The rolling stock had been roughly treated by a 5 year old - many of them need new trucks as well as couplers. Some have couplers attached to the trucks, others have couplers on the bodies. I believe they are all Bachmann and probably just cheapos from sets rather than collector's items.
When I went to look for replacement trucks, I was not prepared for the number of choices available.
In short, how do I determine what kind of trucks to get? How do I identify what I have now? Measurements? Some kind of flowchart that lets me look up trucks based on tiny little differences?
My needs are simple right now - I'm not yet going crazy w/ detailed scale replacements (though looking forward to getting into that as I get into the hobby). Just trying to fix some (ab)used rolling stock, and maybe making them a bit tougher so my own kids can't break them as easily. (Metal instead of plastic?)
I can post pics, but I'd rather learn how to do it so I can understand and be self-sufficient later.
Thanks for any advice at all.
BTW, this post quoted below seemed relevant (I searched the forums first), but again, seemed way more complicated than I was prepared for:
