I think Keith asked how to make power pickup for DCC in the OMI Sn3 C&S Cabooses. Maybe it was a rhetorical question - it sure ain't rocket science. The photos show how I do it. Others may have their own methods.

Frame for 304 a
A .010" bronze wiper wire is visible coming out of the shadow and literally holding the wheel up. It wipes on the tread or the back of this insulated wheel - your choice.

Frame for Cab 304 - b
from a different angle you can see how I looped the wiper for positive yet unobstructive pressure on the wheel. Also note the black wire which electrically ties the two pc board pads the wipers are soldered to and how a lead is passed thru the floor to the interior.

Frame for 304 - c
This is the pc board pad with wiper and pickup wire visible. I used double clad board that is extra thin (+/- 1/32"). It is soldered to the frame of the caboose. You can use single clad board and you can epoxy the pads to the frame.

Frame for 304 - d
This is 304's complete frame with NWSL wheelsets. The originals are Code 110x26" scale with .928" long shouldered axles. I used Code 88 wheels with .917" shouldered axles. The old product number was 7790-4. The new number is 57740-4. These are P:64 wheel sets. So. If you go and buy someone else's wheels I'm just gonna thump ya!
