Have you ever done something "just because" you wanted to do it or try it? I just did. I had fully intended to get started on applying some scenery to the layout when I saw the Kato Mikado traction wheel set that I bought at the Greenburg TS last week. So I picked up my Mike and dropped the wheel set in and put it on the track for a test run. It took 10 cars easily then I added 10 more and it handled them as easily. (this is around the whole layout with its 2+% grade in some places) Now it was a challenge. How many would it pull before it slipped. I took it up to 36 and it was still pulling. Have to put the MT trucks and couplers on some more cars to see what its limit is. Just because.
