I need some info about "buffers"?

Question

Dear railway experts,

I'm looking for some info on the buffers installed between train wagons in order to damp the exerted forces and impacts. I'm not even sure if I'm using the correct expression for this device.

Could you please help me find some articles, websites,... on this issue?

I'd appreciate it if you introduce some manufacturers too.

Answer 1

well, im thinking of starting a business of manufacturing buffers for train compartments.

Answer 2

this site has the addresses of buffer manufacturers in Europe

The United States railroad standard coupler does not allow for external buffers. they are internal to the individual car and built into the draft gear.
