This question came up in a discussion this weekend.

Could they be milled stainless (nonconducting) or steel, nickel silver plated brass or another silvery appearing metal?  They don’t seem to rust and are generally conductive (or we might hear some issues of “wipers” not working.)  Do different manufactures use different materials?

Thanks for your thoughts and knowledge.

I have a question for those with more DCC and electrical/electronic experience then I have.

I have a NCE powercab that I would like to connect to my program track on my modelbench.

Also I have the NCE USB interface I would like to use so that I can download and use JMRI for programming.

And also I would like to set up the Soundtraxx PTB-100 .

I am asking the MHR community for some help in solving a problem I created with my choice of layout scenery. My layout was originally conceptualized 25 yrs ago as a much smaller layout with no intention of adding a backdrop or anything like that. I started this current version with the old idea then expanded it because I had the room to do so. Although I do plan on adding a backdrop at some point, I didn't take this into consideration when I stuck with the basics of how I originally thought the scenery would look. 

Sometime over the course of last spring, I opened up a publication somewhere and discovered a review for a track cleaning car from a company I had never heard of before and have seen little of since.  The car itself was reported to be self propelled, with a vacuum all under DCC control.  Try as I may, I cannot find the publication to go back to the review, but I did write down the details for this curious contraption, searched for it online when I got home, and saved the link for the impending future where my Enlistment Bonus might make something like this happen.
