This maintenance kit is the perfect solution for basic maintenance of your locomotive and track. Use the track scouring pad to clean off any oxidization, dirt and rust and then follow that with the track cleaning fluid to remove any oily residue. The lithium grease should be used on diesel, electric and steam locomotive gearing. Refer to operator's manual for these products to learn how to access the gears and how much grease to use. The oiling pen is the perfect solution for lubricating steam engine linkage and all locomotive pickup roller assemblies.
