These are the new MTH stainless steel plated F7s.
I modified the prototype to look like the real one. This included angling the bottom of the pilot on each side. This give is a more "V" look like the real one. Sorry I forgot to take the before photo. Also From the photo below you can see the trucks are moved in about 1/8 " and I attached the ladders to to the body (moved from the top of the trucks)
I was happy to see I could easily replace the existing scale coupler with Kadees simply by mounting them to the existing mounting hole on the truck. This actually gave the correct height and allowed me use shorter couplers and pull the units closer together using only one diaphragm.
You can see the brake cylinders are under the body and not sticking out.
It looks and operates great on 2-rail track...hmmmm.
Before on right, after on left. Unit on right has pilot the angle mod.
