Chinese made LGB US coaches derailing

[stevedenver]

I have five or six white pass and Yukon coaches baggage, combine, etc., and I am having regular problems with derailments. These cars are fitted with LGB wheels hook and loop couplers I have checked each truck to see that the wheels are properly seated , that the plastic on the metal axel is flush against each other, so they are correctly gauged, and that the side frame of the truck freely articulates. On some of these, I have added lgb metal wheels as well as a few ounces in lead weight in an effort to improve tracking.

I have a variety of other LGB US style coaches, D&RG, DSPP, C& S, as well as some of the bachmann spectrum jackson sharp coaches and frieght cars, and don’t have problems with any of them. I am stymied as to why these coaches are derailing . typically, it’s one of the wheels on a bogey.

I don’t know whether there’s any merit to my question regarding Chinese production. To my eye everything looks the same. The only real difference is the difference in weight of the Chinese plastic versus German plastic

Has anyone else experienced this?

My track work is OK, not perfect. FWIW, my longer lgb German style coaches track just fine as do my lgb amtrak and US streamliner coaches.

thoughts ,guidance , tips will be greatly appreciated. The derailments are extremely frustrating.
I know the simple solution is to simply not run them. But I’m curious if I can remedy “the problem”, if any.
Thanks.

Have you swapped out the wheelsets with a "known good" coach? Also, if possible, swap out the complete bogie (truck) assembly from a similar "known good" coach.

typically, it’s one of the wheels on a bogey.

i had derailments on four axle flatcars from chinese Newqida. (with truck-mounted "bottleopener" couplers)

i found out, that the derailings always happened where after a R1 curve came a straight.

repeated observation showed the following:
when a car entered the straight, its rear trucks straightened up - while the front truck of the following car was still aligned for the curve.

i could remedy the problem with a guardrail (partly on the curve and partly on the straight)

Couple of possibilities, one to investigate by taking off the offending bogie and tracking it to where you get derailments to see if you can notice anything with your eye at track level. This could show up an issue. In addition a small Spirit Level on the bogie could show an extreme variation of cant.

Other option may be to put some washers in the gap between the wheel and axle box. Some items need a couple if washers each side others just the one. I have used bulk purchased M3 nylon washers. I get mine from Squires in the UK. At less than £5 uk for a pack of 100 well worth the cost.
