I've recently been checking into cog railway models...and not finding much. What I have found is a video on youtube of an "HOn3" rack & pinion setup consisting of a locomotive and a coach. There is a second video with a Thomas the Tank engine cog locomotive...both videos are Japanese. I've been unable to find these on the internet. Anyone have any ideas? Otherwise, I am familiar with the LGB cogs...but I'm hoping to find something HO scale. I've also ridden cog railways in both Switzerland and at Pikes Peak. Thanks.
