Lionel Flat Car Track Cleaner Addon

Track cleaning cars are expensive for O Gauge. I've seen some for well over $100 and I just don't want to pay that much. I had a beat up Lionel 6-17407 Flatcar that I have been using for a while with a wadded up scotch bright pad screwed into the bottom. I decided it was time to make this more professional looking.

Parts needed:

1. A cheap flat car or box car to modify with the cleaning pickups
2. Two m2.5x10 screws. I bought a lot of them a while back here: https://www.amazon.com/gp/prod
