Spectacular 100mph Train Crash Test

Was there a calculated energy? Must have been a pretty impressive number.

It was in fact also a crash test. There were dummies, instruments and cameras in the coaches, and BR used the information gained to help in the design of safer vehicles and seats. This was the only chance they'd get to crash a complete passenger train under lab conditions.

it wasn't ment to the 'barrier was a nuclear container they were testing to see if it would with stand that crash.

No, in that case the wall would just disappear. Here, it is crashing into a nuclear container, which has to be strong, because if it exploded the radiation would come out and HOLY SHIT.

That little barrier wasnt enough to stop that beast.

I think that all the old officeworkers used that as an excuse to see some good old destruction and explosions :) the after party was a monstertruck show

IT WAS NOT A CRASH TEST. See that yellow thing? It a container to hold nuclear substances for safe travel using auto motives, and that was a test if the container wont leak, for even the highest of force hit on it. The test was a success and the container did not leak.

The train that hit the flask was not meant to represent the one transporting it, but one that might hit it if the low loader with the flask on it was derailed. In the UK in 1984, only passenger trains travelled at 100mph or more. Freights reach 80mph. The kinetic energy of a moving train increases as the square of the velocity, so this "passenger" train hit pretty hard.

The train accelerated from a standstill with the throttle locked open over 8.75 miles, having been released by the driver turning an external brake valve below the cab door.

how did they accelerate the train???
and i don't wanna clean up this mess!!!!
