With a trolley idk, they're kind of slow and don't use the best sort of wheels for this purpose. A high speed freight train designed to run on shitty tracks without derailing would likely be the best choice, it got the weight and the momentum.

Works for me, jews are like deers in the headlights, they run down the tracks and won't jump to the side into the forest because of their irrational fears of antisemitic trolls living there. No need to tie them down.
I suppose it could be done faster with a faster train? This one has a top speed of 100mph and 7.2MW of power.
With the efficient configuration & faster train 6 million jew heads could be ran over in 3 hours and would only need 300 miles of track. This is the most efficient way of killing I'm aware of, the corpses are spread out too.
