Yes have a 4 Williams fm trainmasters with the magnet at each truck with dual large pittman motors that are great pullers. Can see how the magnets would be useless on some types of track though .
The mth traction tire chart is excellent to use. Have only replaced 2 sets that was put on a used engine bought and a diesel that was bought new in 2002 they seem to last a long time.
