i think that can’t really be answered bc there’s no hard rules on who specifically gets off.

if it’s first-on, first-off then all the original riders would cycle out in as little as 2 cycles. but if it’s first-on, LAST-off then at least 1 person from the original bunch would always be on the train.

if it’s random, who knows! someone who took probability and statistics can work that one out lmao
