Are you stupid? A train is several times longer than a car or bus
and even more times heavier.

No **** sherlock. And consequently they should be built a damn site
stronger than road vehicles. Obviously this is not the case, at
least not for tube trains. If any vehicle crumples up at such a low
speed it doesn't say a lot thats good about the design. Perhaps they
should have used the same team who designed the mainline mk3,
probably one of the safest vehicles on wheels.

It's entirely sensible for trains to crumple on impact, to absorb
some of the force of the collision.

But the front of the derailed car at Camden Town was destroyed rather than
crumpled. Photo at http://news.bbc.co.uk/1/hi/england/london/3227365.stm
This may have been because it hit the wall at an angle rather than head-on.
