old Atlas, Austrian built 3 rail trucks?

Fill the hole with solid plastic rod, center drill & tap for 4/40 and put whatever replacement truck you like in place and throw those old Atlas trucks away.

There used to be adaptors available for filling the hole, but they are not seen often any more.

I cut off the tabs on the push pin, drilled a hole in the center of it and glued it back in the hole. I replaced the Atlas trucks with Weaver plastic trucks and drove the mounting screw up through the hole in the push pin.

I also had some various makes of diecast trucks I thought I might swap, but that large hole for the push pin is a bit of an obsticale.

Petersen Supply in Oregon makes the pin to fill in that hole as wel as the screw hole to place the Weaver Truck for those types of cars!

I have a gondola and four ore cars. Never bothered to change either, never had any trouble with them, other than one broken knuckle. I might investigate cloning a replacement coupler using rubber molds (I obtained an entire replacement truck+coupler so it's not a high priority, but I have the means to do it). If track detection was a necessity, I'd just not run them in blocks long enough to defeat the track circuit.

BTW, they couple to Kadees pretty nicely, well enough to serve as transition cars that don't have to face a particular direction.

I prefer the original Atlas trucks on ore cars, as they allow the ore cars to ride at a prototypically lower height than other 3 rail trucks.  I have around 50 of the ore cars.

Bought a pair of these 20+ years ago, second hand.  The seller said they were made by Atlas.  These cars had sprung, diecast trucks/knuckle couplers installed when purchased.  A slotted screw in each corner of the bottom of the frame holds the body onto the frame.

Those aren't Atlas.  The 70's vintage Atlas cars had a plastic frame with some detailing. They were taller with plastic door guides.  I have several.

Yours look like AMT/KMT cars, or the later Kris or Frank's Roundhouse cars (used the same body mold).  Looks like someone put Lionel Standard O trucks on it.
