Its springs inside of the draft gear, we have to press them to get them out of the draft gear pocket at work

Probably, but I doubt the batteries on the engine(s) could take the charge rate from a mile long stack, and the electrical losses would be astronomical. They have springs instead

I think its air. Hydraulic oil is not compressable and a spring will wear out really fast,

A draft gear uses springs. A cushion unit is hydraulic.

@@IfIcommentIlikedthevideo This type of gear actually uses Hytrel (elastomer). The main action that absorbs energy is actually the friction clutch, not the spring or rubber. That's mostly what helps force the clutch back to neutral position.

Some are longer. They are for cars that you would load fragile stuff in, so they make them much longer.

@@NiceMuslimLady Thanks for the info.

buffers are ridiculous and outdated and cause grief when they lock "buffer lock" from crossovers. so glad our trains here in North America never had buffers.

@@northlanderdude Buffers are great they should not lock together, as the curve radious are limited as with crossovers points. That is why they are elliptical wider on the two sides of the rail vehical to take the curves into account. We have two and four tracks. But we do not have overtaking as you do in the US, it seems to be a very dangerous situation, unless maintenance is being carried out and very carefully signalling/control is in place. It's not necessary as we have lay by tracks for freight say 80 mph to stop and let an express pass say 125 mph. I wonder at you still using wooden tyes (sleepers in UK) with pins to hold the rails, I think we did away with pins in the early 1900's or before and used chairs to hold the rails and about 1950/60 now used concrete sleepers. We have very few derails if so usually a break in the track, defect on the bogie or other engine or train defect. But we dont have the great distances and train lengths 2 to nearly 4 miles to contend with. The knuckle seems the first thing to fail but I have seen the whole coupling assembly ripper out of a box car, as the forces on you freight trains cars are enormous.

@@northlanderdude Buffer lock only happens on model trains, where the curves are too tight.

@@anthonytidey2005 eh rather not add them to American locomotives They'll look Weird That's why When I get lego trains I try to rip the buffers off cause I want to make American type locomotives and buffers make them look werid

Coupling cars together with draw hooks is very dangerous work with those couplers. Plus the draw hooks have low capacity and would not work on the long trains operated in USA, Canada and Australia.

They aren't complex, what is so complex about them? lol

@@OregonCrow OK.

Yup. Those at the controls of these freight trains always take into consideration the "slack action" which is the amount of play between train cars. This adds up quick on a long freight train. Bad train handling can lead to damage of the cars or a derailment. It is one of the reasons why train engineers have to know the territory they're running on like the back of their hand. Being that freight trains take a while to stop, engineers need to be able to make smooth adjustments well in advance of a stop or speed restriction.

I wonder if that's where bumpstops on desert race cars came from.

Yikes!

Oh man, thinking about the energies involved in a fully loaded torpedo ladle car and then trying to build a damper to deal with that. That is a challenge. I'm not surprised they got smooshed up, especially if whoever was driving the power was careless with their speeds.

darkridge it’s just explaining how the trucks work on curved tracks.

It's exaggerated for clarity.

Not so much but super elevation is a common thing

Thanks. We're currently updating our draft gear video that also talks about other punishing forces railcars experience. It's going to be a great. One. Make sure you subscribe to our channel to be alerted when it posts.

Done !! and looking forward to it!

Disculpe, en este momento no tenemos el video en disponible en Español. Si esta interesado puede llamar a 630-232-3000 y alguien le puede explicar como los side bearings controlan el carro en una curva. Gracias.
