Walthers taconite cars

[spud7378]

Hi gang. I have a set of the walthers 12 pack of Michigan style taconite cars. I have changed the dummy couplers to kadee 5's. they run great going forward( being pulled) try to push them. Hold the train. They don't go without derailing going through switches. I've checked with an nmra gage the points , the flangways on the switches, everything checks out. I have no problem with the round house ore cars or any other car going through, just the walthers cars? It's not just 1 switch in perticular it's all of them, pecos, and atlas.

Any help please

Did you also check the weight? They're probably too light.

Did you also check the wheels with your NMRA gauge to make sure they're in compliance?

Ok weight was off by 1.5oz so added the weight and checked wheel gauge. They run much better , but they now only pick the shinohara curved switches?
