Hello, I have a E&C shops Jhonstown Coalporter. It keeps derailing on one of my switches, namely a peco medium radis switch. Any ideas?[:'(]

There could be several things going on here.
First… is this the only piece of rolling stock that fails while all other equipment functions well… If yes then pursue the car… if no go after the turnout.
Have you run standards on the car… weight to NMRA standards? coupler height and flange width? Don’t go any farther until you can say these are all good.
After that… look for truck issues… Try turning around the car and watching for a failure… if it goes with the brake end first better than the other it is probably a truck issue.
Too tight… not square…not level…are they even real trucks? or some plastic frame junk… Look also at crud build up on the flange from extended operations.
After that… is the car sitting so low that the truck is getting tangled up in the underframe or draft box.
By now you should have it solved>
see ya

It’s none of those…I’ve added KD’s, steel wheels, and weighted it. Also,this car is just going streight, no curves anywhere near the frog…
Sakel…
And all other equipment goes through there acceptably? ? ?
see ya

everything else runs great… even my string of 5 stock athearn bb 34’ hoppers
This investigation requires you to do many trials, repetitions, while you use magnification and back ligting to see where the problem first begins to happen. Often it is at the back of the item, not where the derailment takes place. I have had locomotives derail on turnouts, but it wasn’t until I recognized the leveraging effect of dips in the rails rearward under the cab that I understood why the front wheels were derailing.
after intense invesigation[;)], i have found that there was a clump of ballast in a crossing right before the switch. After i removed the clump, everything ran fine. Thanks for all the help everyone![:D]
