You can't just mine hydrogen - it has to be produced.
One might wonder if this falls under a similar umbrella to EV's - many of which are actually coal powered.
The railroads have experimented with hydrogen power.

Which takes energy itself, which has to come from somewhere.
It can also take a fair amount of energy and environmental disruption to produce fossil fuels like coal, oil and gas.
Alberta is trying to promote 'blue hydrogen' made from natural gas as carbon-neutral and eco-friendly by way of capturing the CO2 that is produced as a byproduct and pumping it underground into suitable depleted oilfields.

Blue hydrogen is nearly the only zero-carbon fuel approach that makes remote sense for modern transportation needs. It's cute that the locomotive development projects are using green hydrogen, but I doubt that will be effective at fleet scale, even for one railroad.
The sequestration easily occurs due to the phase change of CO2 as you compress the hydrogen to delivery pressure (which has to happen no matter how the hydrogen is generated).
I have not yet learned what metallurgy Siemens is using to avoid long-term hydrogen embrittlement. If it is barrier hard coating, expect some surprises down the line.
