Kids and collectors alike enjoy Lionel trains. But while the trains provide hours of enjoyment, they also require a lot of maintenance. Each part relies on the other to work. If one part like the tracks or transformer is not working, then none of your train will work. However, there are steps you can take to repair problems as well as preventing further issues with your Lionel trains.
Examine each piece of track for signs of oxidation damage, which will either appear as crusty white or green. Take an oxidation remover like BioClean or Meguir's and make a mixture. Then dip a track with oxidation into a mixture. Allow anywhere from three to five minutes for the track to set. Remove the track and dry it with a clean track.
Rub down pieces of of track with a towel containing a small amount of lubricating oil. Continue putting oil on the towel as needed. Buff the track with a clean towel; this helps create a slick surface for the train.
Repair any bent pairs by using a pair of pliers. Use tweezers to reset disconnected parts, then screw them back into place using a screwdriver.
