Yes I noticed the disk brakes. If I remember correctly there are other designs with a single disk brake, but I don't remember the RR's. Another interesting fact about transit wheel sets. The design shown has a inboard wheel and out board journal bearing. There are other transit wheel designs that have a outboard wheel and inboard journal bearing design. This is defined by the truck foot print. The first design, outboard journal bearing, the wheel is pressed on and then the journal bearing is pressed on and spiked as an individual component. With out board wheel the journal bearing is installed first and spiked against a shoulder. Then the wheel is pressed on at maybe 100 ton and then spiked against the journal at approx. 10 ton. A little more difficult to do when working with a 100 ton force. This is from my memory of about 30 plus years ago. Just for reference a locomotive wheel is pressed on at 105 to 155 tons referencing a 10 inch diameter. Rule of thumb is 13 tons per in of diameter. Just some details.

Speaking of Hyatt and Timken bearings on locomotive trucks, I took some pictures of a couple of NS SD40-2s that sat on a siding in town, idling all weekend. Both units were originally built in the late 70s, and looked like they have done a lot of hard work.
Loved the sound of those big 16 cylinder 645 EMDs idling.

One had an assortment of axle bearings.

That's alot of wasted fuel, and unnecessary emissions. No local/other rules about that?

I don't believe so.
It was pretty cold, so shutting them down could have made restarting them difficult. At least there was no visible smoke coming out of the exhausts.
Thing is, where they were parked, it is only about 10 miles from the NS Elkhart yard.

I saw one many years ago come through town. I remember it had four two axle trucks on each end, and some kind of large piece of machinery suspended in the middle.

"Idling switchers use between 3 and Il gallons of fuel per hour depending on the ambient temperature. "

An EMD 16V645E3 burns about 5 gallons of fuel per hour, so they probably burned up about 600 gallons setting there from Friday afternoon until Monday morning.
