Locomotives powered by Hydrogen?

[densa44]

I'm not trying to start trouble, just asking. How do these engines work? Is it the same technology as steam engines, diesel engines, or something new?

Thanks.

Good question.

If I had to guess:

I suppose that there’s a couple of ways to do it - one is to use hydrogen as a fuel in an ICE engine.

Another way is to use a fuel cell to convert it to electricity by combining it with ambient oxygen to create the electrical current and provide float charge to onboard batteries.

I believe that many locomotives are electrically driven (diesel powers the generators) so the second option may be the most likely…

And in case of a railroad crash- do we get a thermo nuclear bomb going off? Asking for a friend…
