Railcar truck set nomenclature

Compare a railcars "truck set" as compared to a railcars "wheel set".

Thank you I'm a rail fan and a railroad artist I haven't seen a truck that up close and detailed before thank you that's going to help in my future railroad artwork peace out have a great day

[@robertbowman3406]

Just for chat each wheel weighs in at 1,000 pounds each and each axle weighs in at 500 pounds. Each spring is rated for a certain weight handling. When there are two springs they are called nested as there is two together. The Timken wheel bearings, I found out from the Timken people, are rated for 1,000,000 to 1.5,000,000 miles before they wear out. If the car sits for over 1 1/2 years with out being in service it is advisable to replace them before they are put into full time service. The FRA (Federal Railroad Administration) outlawed the old journal friction bearing as they would get over heated and cause derailments. I remember working for the Great Northern way back in 1966 at Hillyard, Washington and there were three men on each side of the train who would open each journal box door, give the bearing a few squirts of oil and then close the doors. The train would move very slowly for this service.

[@robertbowman3406]

@ I would have to guess on the total weight of the truck assembly. Lets say around 10,000 pounds or 5 tons. When it comes to traction motors I have no idea what they weigh.

[@robertbowman3406]

Taylor I think I gave you a underweight of a complete truck. Take the completed axles and wheels, 2 side frames and 1 center bolster, all the springs and all the brake rigging I would give a total weight of about 20 tons per truck.

[@jaysrailroadcorner5403]

@@robertbowman3406 That’s waaaaayyy too heavy. A bolster weighs less than 1,000, same with the 2 side frames. The wheel sets are the heaviest and they weigh about 1,000 each. All in all, the assembly could be no more than 5,500 lbs.

Wear liner is also known as the GREASE DISC. The grease disc goes over the CENTER PIN. The pin rests inside the CENTER PLATE (or) BOWL. CONSTANT CONTACT SIDE BEARING. They have a composite rubber in them to cushion the car in movement. Some have a steel wheel in them called a roller bearing. Also. Truck sets and wheel sets ARE NOT ALLOWED TO TOUCH THE GROUND. Every single set in this frame is going to need a roller bearing inspection. They come off the truck and straight onto rails. If for ANY reason they touch dirt, gravel, grass, pavement, concrete, black top etc.. they must be put under inspection per the AAR Field Manual. Even if it’s a repair facility, home shop or interchange. They must not touch ground.

[@CuriousEarthMan]

Great video, thank you! Just the detail I was looking for! Why don't the pivot pins ALL lock uin place as far as up and down movement? I would think it might be a safety issue for cars bouncing off the pins. But I guess without turbulence, dropping away of the truck or rolling of the car body off the pins might be rare.

[@rodneycassidy6037]

Those are constant contact side bearings. No gap allowed. It has a certain amount of preload depending on which style it is. Looks like stuckie ( believe that's how it's spelled)

[@ParagonBridgeWorks]

A. Stucki Company kind of has the market cornered in constant contact side bearings. They do a great job and I have seldom seen gross failures. Heck, they seldom ever need replacing. It is really a great system and they make a great product that is easy to work with. Hmm. After thinking about it, I really like A. Stucki Company.

Many passenger cars and locomotives have 3 wheel sets per truck set.

[@ParagonBridgeWorks]

The only 3 wheel set trucks I have worked on have been for the military. The railcar body itself, including the center plate, were identical to the traditional 2 wheel set trucks. Same wheel sets as well. I have never worked on locos or passenger railcars myself.

[@ForesakenVengance]

Damn I just changed a full set the other day. Should have recorded it

[@darthsimmons6957]

What about "Slack Adjusters", how they work, using compressed air. Everything is held together by gravity, & pins, with only cotter pins, in the ends of those. If you lift up the frame bolster, those wheels & axles will roll right out from under there. The frame bolster just sits right on top of them and the roller bearings. The freight car, just sits on top of the trucks held on by gravity, with a just kingpin keeping it from sliding off. Not bolted on. I'm surprised no grease is used on moving parts. That makes them easier & cleaner to work on. Semi trucks are supposed to get grease every time before the hook on to a trailer.

[@ParagonBridgeWorks]

Yea, it's kind of weird how everything is held together by gravity. There are some parts that were once greased, back in the day, but are now fitted with non-metallic wear liners (looks/feels like hard teflon). These areas include: center plate liner which goes in between the center plate and the truck bolster bowl, coupler carrier wear plate which goes in between the coupler shank and the coupler carrier...I think that is it. Some friction castings have a wear liner but not many. Box car doors still take a lot of grease. I have never thought about how slack adjusters work. They dont fail all that often...and they are made by the same company that makes bathroom urinal valves (sloan and ajax). Weird.

[@MacBeach]

These look like a job for WD 40!

[@professorx8785]

You should have explained the buttons on the side frame

[@raylouis]

What does the painted writing mean on the side of the wheel set?

[@ParagonBridgeWorks]

The only federally required "paint" on the wheels is a small "H" that get stenciled on the wheels. The "H" means that the wheel is "heat treated" and "curve plate". This refers to the actual wheel plate itself which is the part of the wheel between the axle and the "tread" or wearing surface. The older wheels were a super simple flat plate of steel. The newer wheels looks more like an "S" if you were to cut a cross section out of the wheel. This helps with heat dissipation. All of the other stencils on the wheels you see are from the manufacturer. Some of the wheels we get in are almost brand new with the mfg stickers still on them. Some only a few months old. Those mfg numbers vary and are not very important. All the important stuff is cast or engraved into the wheel, such as mfg serial numbers, manufactured dates, heat treat classification, and factory ID.

[@raylouis]

thank you

[@driftspecs13]

"H" is the only required lettering per FRA, but Greenbrier provides my rip tracks' wheels and they'll sometimes--not always, but sometimes, be stenciled "PREM" for a premium wheelset, "TURN" for a turned/reconditioned wheelset, or "NEW" for a new wheelset.

[@jaysrailroadcorner5403]

[@louisletourneau3429]

So the cars are just deposit on the trucks with the pins centered in a hole in the bolsters . No attachment of any kind ?

[@brush8766]

None , not even the wheels are attached

[@jaysrailroadcorner5403]

Naw. On the truck mounted brake systems you’ll have break rod/lever attachments and/or a cylinder hose. But for the most part it just sits on a pin. Sometimes I’ve bent the pin and tossed it and let it ride with no pin.

I notice that none of the wear liner bowls have no grease in them, got to have that as the truck will be hard slewing around curves and will climb the rail, i thing a lot of derailments are the cause of this, i work for a class 1 rr and o have never seen the car knockers lube these things, not on cars not on engines and then they wonder why some of these derailments happen.

[@ParagonBridgeWorks]

derail14 Hmm. That is very interesting. I have never greased the center plate. I thought the non-metalic wear liners took the place of grease. As a matter of fact, they are also called "lube disks" so I don't think grease is needed. I do recall grease being used by the repairmen when I was still a grunt, not worthy enough to use any tools, way back in the early 1990's.

[@whiteknightcat]

I recall seeing TV commercials for some oil company way back in the 70's that was illustrating some of its innovations. One of them was the lubricant for the center plate - they consisted of round flat discs. Four or five wear simply tossed in the bowl and the car body lowered in place. I presume the weight then squashed the discs into a paste similar to grease. The one shown in the video looks like it might be similar to the product shown in the following link: www.rrtoolsnsolutions.com/lubricants/LubeDisc.asp

Ok there Mr class one I work at a class act Railroad, and your right us car knockers don't put grease in the bowls .why you might ask ? It's not FRA nor AAR prohibited . That lube disc is all it gets . Most of derailments are on the account of poor track conditions and poor train handling.

And both side of the weel has brakes on it. in passenger cars called vagon is alot like Minden Deutz Goosneck or Görlitz. the new one with disk brakes has different design and is alot of types. mostly are state of the art, fabrication technologies are differerent and on passanger cars has magnetic brakes too.

Round block over bearing is also known as a "journal". Stop over explaining yourself because it makes you stutter and loose train of thought on part names.

[@ParagonBridgeWorks]

+Charles Stevenson I have heard of the "roller bearing adapters" called "journals" but the AAR rule 37 specifically calls them "roller bearing adapters". In fact, the entire book only refers to "journals" as the area on the side frame where the adapters mate to and does not refer to that term as an actual part. But, I have heard them called "journals" by some people. That's just my humble opinion. I hope you enjoyed the rest of my videos.

[@brandon_quig]

The "journal" is actually the end section of axle on which the roller bearing is mounted. The area on the the side frame that sits down over the roller bearing adapter is call the "pedestal jaw".
