An obstacle appears appears, and the train goes into emergency braking. You’re now stopped between electrified sections. It’s going to take hours to get moved, and the delays will ripple through the system. A diesel will have to be dispatched… except it’s entirely possible it won’t be able to get you because there are trains stuck between you, and it’s not like they can pull onto the shoulder. These sections are sometimes miles long.
