Some people have never had to cut through chain quickly, and it shows.

Give me 10 minutes with my cordless angle grinder and a fresh pack of cutting discs and I'll have every link cut from head to toe

Or 20 minutes with a hacksaw and I'll at least have a link cut that allows me to unravel the chain.

Or just make the immortal person Jeff bezos and I'll just call it a day?

    Well, since the train passes every 10 seconds, I'd say you reasonably have to batch this job in 5-second bursts, maybe shorter to be safe. Even if you focus on just one link per side on this "very heavy-duty chain", I'd say this poor soul would die at least 30 times just while you're working. Plus imagine all the blood you - and your tools - would be splattered in. What's that going to do to your angle grinder and your fresh cutting disks?

    Without getting into specifics, I'm 100% confident I can cut through up to 12mm of hardened steel in under 10 seconds with one, assuming I get the alignment right and the steel isn't going to shift on me. Given it's being called "heavy duty" chain, I'm going to assume a layman's version of that and say 12mm is probably overkill, but let's just go with that.

    10 seconds of grinding. I'll give myself 3 seconds to run in, 3 seconds to run away. 6 seconds to cut, we'll go with 4 of those actually making contact. That's 3 trips per half-link (you need to cut through both sides of a link to pull the chain apart) so 6 in total to break one strand.

    I'd say 30 deaths is generous.

    And again without getting into specifics, blood on brushless tools doesn't do much, especially if I use some corrosion resistant coatings on the sensitive contacts.

    Ultimately though, one would hope the immortal being is willing to accept the temporary trolley torture if it means the others can be rescued
