Rough XL Driver in 3D

Making some progress. Might have this in a 3D printer by the end of the week.

XL WIP

Getting the principle dimensions of the XL Driver down. Once I can go from design to 3D printer with a known good model. I can scale up the radius for an XXL.

Single axle rear truck

For GT3604 and CN5288

713 handles switches

There's 12 studs between the flanged drivers, so the question came up about how it handled switches. It works pulling from both ends and pushing from the tender. Pushing from the pilot truck seems to give it just the right amount of force to cause the front mains to catch the guard rail and derail as one would expect.

GT 713 WIP

With GT 3406 in the background. I think the tilted wafer logo looks sharp on the tender.
