I recently purchased a roller set and have been experimenting with my various locos mounted on the stand. Tonight, for the first time, I tried some DCS engines. I made a jumper cable out if 18 gauge wire and alligator clips and clipped to the leads from my stand to the center rail and outer rail on the track. Placed an engine on the stand and did fired it up. The engine was recognized, it started, all functions seemed to work. But then I turned the thumbwheel to make the wheels go forward and noticed that they were going in reverse. Put another engine on there and it did the same thing. Put them back on the track and their directionality was correct. Any ideas as to why the direction is reversed on the roller stand (I have center rails connected to each other and outer rails connected to each other)?   For my non DCS engines, I've been using a 1033 transformer as power for the stand. For these MTH engines, I jumped it straight to track power.

I tested it again this morning and discovered something interesting. This time I took the engine off the rollers and put it directly on the track mounted on the roller stand (in front of the rollers). The direction commands worked correctly. Put it back on the rollers and again the direction was reversed. So......perhaps it had to do with DCS signal going through the rollers themselves and getting altered?

John,

And you won't.......my silly mistake. Just went down there again. It was easier to see the rollers than the wheels, so I used a narrow beam flashlight. The roller system works like gears. Main gear turns in one direction....connected gear turns opposite. The train wheels were going clockwise, rollers counter. All is good.   Love this roller system, though.
