John- I took a look at both engines. I couldn't take the couplers off of the 44 because they are under the trucks but I could do it on the 70 ton. The coupler arms are extremely short and do not offer much swing. There is a small centering spring under the coupler which I removed for the test. No difference when I tried several different cars through 027 curves. I have a pair of 042's and things were OK through them.

The tension was reduced without the spring but not enough to make a difference.

Sorry I couldn't offer better news. Now I have the same problem........ disapp

I guess we both need wider curves like GRJ has.

For comparison I checked a K-line Plymouth (bottom engine) and they have much longer coupler arms and better swing.
