This week on Ice Road…Oh wait, that’s IRT[:D] Okay, now to my question. What are the little plastic rings included in IRC’s ( Intermountain Railway Company) freight cars used for?
Samuel,
I’m going to guess that it’s spacers for the bolster so that the frame sits higher off the truck in order to raise the height of the coupler boxes - if needed.
Tom
Oh. Thanks for the info.
