NW-2 Cow & Calf

Overall:

Thankfully, there are no traction tires on the wheels. I will probably remove the sliders and see if they still run well. Have not tried the smoke units yet. I think they could stand a bit more weight. I have a cow and a calf so far. Many railroads use a cow and one or more calves. 

 Kadee Couplers:

I trim off the tang, leaving about 1/16" of the thinner tang projecting from the thicker part. This allows you to use the existing hole that held the hook and loop. You can use the screw from the hook and loop. This is for 831 couplers.

Kadee also recommends cutting 5/8" off the tang, and you also need to cut 7/16" off the gearbox shank, and  trim a slot in the lid 11/32" wide and 5/32" deep to match the sides of the pivot arm. This will allow closer coupling, and should work on curves under 8 foot diameter.

For larger curves, over 8 foot diameter, you can use the 787. I have not tried this yet, to see if it gives close coupling.
