Hi Jim,
I think they're called "contact assembly" or similar, like this one on ebay ...

As far as material, you need something stiff, but non-conductive. What comes to mind is a blank circuit board plate, like you might be able to pick up at Radio Shack. Not sure if it's the exact same material, but it might work. Something sorta like this, but perhaps without the holes ...

Maybe you can find the exact contact assembly with a bit of ebay / 'net searching?
Anyway ... good luck!

EDIT --
Lionel calls them "Contact Shoe Assembly", as shown here:
