Installation of the "bumping posts" happened today at Conestoga.
Rawie seems to make almost all of these around the world.
Functionally, the bumping post can slide along the track. As you can see, there's a clamping element that is attached to the rail head. It closes around the head with springs, and a specified force can be applied. So, when a train impacts the bumping post, it can slide along in the same direction with a carefully engineered resistive force. The clamp at the train-end prevents that end of the bumping post from lifting up (which is why it wraps around under the rail head).
