America's Strongest Bumping Post

Hello,

I am really interested to know the strongest bumping post or one of the strongest that's out there. In particular, I want to model this and I so I'm trying to build it into a layout and then run the correct number of wagons and speed for it.

I think, when I look at most bumping posts, they don't look to be capable of taking very high speed trains - most of them just seem to be for trains in sidings or freight yards presumably running at very, very low speeds - but perhaps I am wrong? I have also seen bumping posts with an earthen mound in front of them - or even sand - but I guess for these the train will derail before it hits the bumping post? Whereas I'm interested in keeping the train on the tracks.

Any help would be really appreciated.

Thanks!
