Friction end stop testing China. ----------- See Pinned Comment.

These are made to stop trains at typical yard (shunting / end of line / railway station terminus) speeds. They are lower speed bump stops. It's the choice between hitting something solid or rolling off the end of the track. Express trains and fully loaded long freight trains.... Nope....

@Life_N_Times_of_Shane_T_Hanson: even (specially) in a yard it is needed sometimes you can still get runaway cars... but you are mostly right, normally it should not be an issue because the speeds should be low... not sure how railways (gov./companies/etc.) work in china or their hireing practices, would rather be safe than sorry because some idiot wanted to try to speed something up or take shortcuts.

@sbseed: Shunting / train assembly yards are tightly controlled environments, the speeds, the gradients etc., are very tightly controlled and designed to operate in very specific ways. The buffer stops are for slow speed "safe stopping" = usually at end of line stops at stations and on blind end rails. https://www.youtube.com/shorts/bMzOJCOGZM8 --------- https://www.youtube.com/watch?v=D0RDavyDjik ----------- The historical testing is good, because you can see the differences between a rigid stop and a "braking" stop. --- https://www.youtube.com/watch?v=uYByVsC_IxY --------- https://www.youtube.com/watch?v=A6Aa-rrdjbw -------- https://www.youtube.com/watch?v=iKxpqVNjOR0 --------- https://www.youtube.com/watch?v=ACNeDxew5Q4 ----------
