Aerospace parts don't stand a chance in a train wreck. They just aren't designed to withstand the forces that (heavy) railroad equipment can place upon them That was the point that I made much earlier in the thread...
I'm not sure what an empty 737 fuselage weighs ... but if you consider the MTW
of around 174,000 lbs (for a 738), that's the entire plane ... wings, tail, fittings, passengers, freight, fuel, engines ... etc. Subtract all but the shell, and it's probably not all that much, comparatively.
Now ... railroads ... nothing
on a railroad is light. Or small.
It's not atypical of a freight car to weigh 40-60,000 lbs ... empty
. A single axle, with two wheels, alone, is several thousand lbs.
locomotives (GP9, etc) are a "mere" 235,000 lbs. Large ones (SD70, etc) are almost double that.
So if you consider the railcars in this train, they were probably around 100,000 lbs (for the 737 flats), up to a max of 234,000 lbs on other freight cars. Multiplied by however many cars are in the train. Plus a number of locomotives.
This isn't millions, this is tens of millions of lbs.
Any time a train moves, that's a tremendous amount of mass in motion ... the kinetic energy is just insane.
A small, thin, lightweight, and fragile aircraft or aircraft part is just a bug on a windshield by comparison.
