Cleaning The Wheels, Tires and Track

Periodically check the locomotive
wheels and pickups for dirt and
buildup, which can cause poor
electrical contact and traction and
prematurely wear out the neoprene
traction tires. Wheels and tires can be
cleaned using denatured (not rubbing)
alcohol applied with a cotton swab.
To clean the track, use RailKing Track
Cleaning Fluid and a clean rag or
denatured (not rubbing) alcohol.
Unplug the transformer and wipe the
rails of the track, turning the rag
frequently to ensure that you are using
clean cloth on the rails. Thereafter,
keep an eye on the track and clean it
when it gets dirty to ensure good electrical contact and to lengthen the life of the tires.
