  • If I ran the local power grid I’m not sure I’d want cargo trains using line power for traction, unless there was some mandated weight or length limit 🤔

    Without some cargo limit I think sections of the line’s voltage will just collapse under the current being drawn, whenever the cargo train moves off from a complete stop - especially if it’s a multi mile long cargo train that seems common in the US


  • Fills up in a comparable time span as diesel locos, and the hydrogen storage would be much lighter compared to equivalent battery storage. No need for an onboard AC/DC generator for the traction motors too, as would be the case if it was diesel powered.

    To me it seems like an ideal diesel loco replacement

    I assume it will be hauling cargo, not passengers…
















  • How?

    If you live in the US, most likely data brokers.

    Really seedy industry centered around buying and selling your personal information, compiling public records from government sites to build a profile of your location, previous addresses, jobs, biological sex, given sex, phone numbers etc, and then cross referencing that with online data from ad trackers and targeting to build a more detailed profile of who exactly you are specifically.

    This stuff doesn’t even scratch the surface too.

    US law enforcement has also been openly using data brokers to bypass certain privacy protections/rights granted to people who live in the US, where things like a warrant or subpoena would usually be necessary
