Lubricate train and tracks

[CoopTrain]

I have the Royal Scott serialized train set, HO Scale. It has been in the box for over 20 years. I took it out and it ran well. In the meantime, should I apply any lubrication to the engine and cars? If so, what kind? Are there instructions on how to apply it?

The tracks look clean but do I need to lubricate them also? If so, what kind of lubricant and how?

Thank you.

If the track has been stored away, it might be a good idea to wipe down the rail heads with some denatured alcohol to clean off any accumulated "stuff".  You don't "lube" track.  I know some people use Whal clipper oil on their railheads but that is supposed to slow down oxidation.

Wahl clipper oil can/is used to clean the track.  Works well for that purpose if done properly.  I like to place/rub the rail with some on a cosmetic q tip (not your standard "Q-Tip").  You can see what comes off the rails, on the q tip, then rub/clean off the rails with a rag if you desire; as long as there are no puddles of oil, things will work fine.

For lubing locos; oil on metal parts like motor shafts and bearings and grease for gears.  There are TONS of hobby oils out there and any grease rated for PTFE will due.

Coop, do you know how to get the shell off of your loco?
