Thanks Chris
I wonder if the yellow risers would match with two 3/4" risers on top essentially, instead of double height more like one and a half height. Now that I see these engines, I guess I have always seen the cogged wheels but never knew what they were for. I like how they climb and also how the cog makes a descent very smooth. Wonder if someone at Trackmaster brought these up when they where looking into re-designing for the roller coaster Revolutions.
