Final answer:
Passengers are the ones who benefit the most from train operators making accurate stops at the stop markers during rush hours.
Step-by-step explanation:
If train operators make accurate stops at the stop markers during rush hours, the one who will derive the greatest benefit is the passengers. By making accurate stops, train operators ensure that passengers can easily and safely exit and board the train. This reduces delays and congestion, improving the overall efficiency of the transit system.
For example, if a train operator consistently stops short of the stop marker, passengers at the front of the train may have difficulty exiting, while those at the back may struggle to board. On the other hand, if the train overshoots the stop marker, passengers at the front may miss their stop, causing inconveniences and delays.
