I’m very intrigued by this no glue snow plow. Would be able to share a bit more about that?
For sure! I modeled the plow with a ledge that sits on top of the sill step? and a barb that goes under the coupler.

The barb is only .4mm wider than the slot in the sill for the coupler, so the frame flexes slightly and then the ledge sits onto the sill and locks it in. The plow can be installed / removed from a fully assembled loco.
In this photo you can see the plow half way installed. The barb is flexing the sill and the ledge hasn't landed in its home yet.

In this photo you can see the plow fully installed from the bottom. The barb has locked it into the sill, the flats on the back of the plow are hard against the pilot face, and the ledge is sitting on the sill step.

I went down this path because the pilot handrails would be almost impossible to install/remove if the plow was glued on, and I think it turned out really nicely. The plow is held on securely, but if it gets bumped hard it can move and just be reset without breaking.
