Very interesting footage - now explains why there are additional rails in the four-foot on that road  |

Presumably the extra rail is to strengthen the formation and resist the force exerted by the buffers. I read on an other list that a parcel van got itself stranded (at or near Harrow ?) when it suffered a rough shunt and collided a speed into a conventional set of buffers. The track tore away underneath it and left it stranded for some time before recovery. Both bogies were still on the rail but there was a large gap between them that took some time to bridge.
Going back to the video, I am surprised there wasn’t more noise and sparks considering the energy that the buffers had to absorb…
One watt is one joule per second.
1 Watt = kg.m2.s-3
231,000 kg at 3m/s brought to rest in 4 seconds = quite powerful in my book

One of the main-line termini (Kings Cross?) was fitted with buffers which, according to the manufacturer's claim, could stop a 400 ton train travelling at 20 mph "without inconvenience to the buffers".
