Truck kingpins?

[thomasjmdavis]

If Americans called "trucks" "bogies", that would make things much clearer.  Trucks should really be rubber-wheeled vehicles which travel over any solid surface.  Bolster pins is also a good descriptive term.  Aren't those called "kingpins" in 1:1 railroad lingo?

Except railroad "trucks" came first- in common usage well before the internal combustion engine. They should call the things on rubber wheels "lorries."

I have never, ever had a pin fall out, tbh.

If I have one that gets loose, I squeeze the end with a pliers to make it an oval and it stays in the hole.

Doug:  That's exactly what I do - and have been doing for over 50 years!

My all time worst Catastropic Derailment was a dropped kingpin on the front of an 18-car loaded piggyback train, headed downhill on a 2% grade.   Pin dropped, and landed between the ties to make a PRECISE ramp/derail, so that every car behind it, under gravity, rolled into the pin, derailed, and rolled off the roadbed and hit the floor below, a 48" drop.  Oh the insanity!   More $$$ damage than I've ever had before......  yes, I glue/squeeze/check pins REGULARLY now!!!!
