>>1931139Anon I think you need to go stand beside a locomotive again to get a sense of the large scale of locomotives and rolling stock. They are almost entirely made of pure metal and are carrying massive amounts of cargo (both products or people).
The average locomotive weighs a couple hundred thousands of pounds/kilograms. A single pic related (a GE ES44AC) weighs nearly 500'000 lbs but they're usually run in sets. Each piece of rolling stock or train car generally weigh tens of thousands of lbs whether it's a hopper, passenger car, intermodal flatbed, tank car etc. This goes up if there is actual freight or passengers. Let's say each hopper is filled with wheat or coal, the weight can then be well over 100'000 lbs per car. So a full train usually weighs a few million pounds of pure steel, various materials and is propelled along at high speeds with engines the size of a bus capable of putting out thousands of horsepower each.
Very few things would crumple a train. You can drive a train through several meters of pure brick wall and it probably wouldn't even derail. No car or truck in the world would be capable of crushing a train. I'm not even sure a main battle tank could do it. When a train gets crumped it's usually only because it crashed into another train.
