I remember there was a meme that showed how to solve the experiment, where they quickly switched gears and managed to get the trolley to drift over both rails successfully killing everyone.
I have no experience with railroads, but I heard that if you leave lever in intermediate position, the trolley will go off the rails completely, so only casualties would be broken trolley.
That being said, I like their solution. umu
fyi, this is actually a parody of Dragonar OP (the mangaka is mecha hardcore fans so a lot of his works usually refer to some of the classic) https://www.youtube.com/watch?v=ItCMX3A1qaE
