It doesn't help that actual trolleys are called trams where I live, so I think of trolleys as philosophical constructs that don't have a real existence.
Actively making a real life or death decision is quite a lot different than reasoning though a game.
If you are in a burning, sinking ship and all going to die for sure, it's still immoral to rape someone.
So the argument still stands, the difference in the consequences, when considered outside of any context, is simply not worth the mental effort to figure out if the lever should be pulled. The exercise is only interesting because it provokes to think about real life scenarios.
Edit: On the other side, if you really decide to not take more context, you just destroyed the only existing trolley of the universe.
Does anyone really still call them that? A trolley is not a tram, it's a trolley, and harkens back from last century. In the US, some people call them trams, most of us call them trains. Portland does have a special version they like to call a streetcar, though. Functionally a light rail train, but runs in normal lanes of traffic.
Yeah, when I clicked on the link I was hoping that finally someone had solved the problem of never having a pound coin to unlock trolleys at the supermarket.
