Any good service manual has this information. I know some of the Lionel train set manuals were extensive with product information on transformers and accessories.

LW Hum

hum is a key feature on buying tansformers, many have it. Most of the time it cannot be fixed if

too loud. One trick is to tighten any frame work against the plates to stop the vibration.

Postwar Engine Wheel/Part number

Quote from Teledoc and pdf files from Gunrunner John. It was easier to copy the files than the post. I am getting rusty.

I have the Postwar Engine/Wheel part numbers finally done, so that anyone looking for what wheel is used on a particular engine will know what part number to use. I compiled a list for Prewar O and 027 engines and this Postwar list, for anyone to use as a reference. Sorry that it is only in .JPG format, but someone like Rkenney usually sees these lists I post, and does a .PDF conversion. I use both XP and Windows 7, and by using the right mouse button, you can save it to your computer for your own collection.
I compiled these lists, so that people can search in one location, and find what you need.
