Very nice, but unless you’re doing some tricks I can’t see in your image, your example locomotive won’t be able to handle corners.

You won’t be able to put three of these wheels next to each other and have them go around Lego curves. If you move the middle wheels in a half stud, I think it will work - but that adds another layer of complexity with attaching the pushrods. Also, if you want to run three wheels together, it makes a very tight threshold for the shape of the flange. You need the flange big enough and angled enough that it won’t try to climb up the outside of a curve, but it still needs to be small enough to fit through the switches.

My suggestion would be to just mold the counterweight into it, and make just one mold. Off the top of my head, I can’t think of a time I wouldn’t want to use the counterweight...

So, when can I get a couple dozen in black? *grin*
