I don't use WD40 on my trains at all! I use a lite oil such as three in one oil or Labell 107 which can be purchased at most hobby stores.

The ingredients of WD-40 are 50 percent mineral spirits, 25 percent liquified petroleum gas, 15 percent light lubricating oil, and 10 percent inert. Far from containing water, it was designed to displace water: The "WD" stands for "water displacement". Nevertheless, as Lee says, it shoudn't be put on a motor commutator.

You may not need new brushes if it has been sitting for a while, just check the surface of the brushes-are they clean and not little pit marks? Brushes can be sanded down a bit and re used, armature plate can be cleaned with a pencil eraser on a pencil. Don't use WD40, it is water based and won't work well as a lubricant.

Just make sure you avoid any oil/greese on the commutator face or on the brushes. While you are at it, might as well get new springs and brushes anyway.

Put oil on all moving parts except the gears. The gears should receive a small amount of grease. Oiled parts would include the side rods, valve guides, wheel axles, and armature shafts.
Good Luck, Earl
