I don't think it's a matter of the lying. It's just a matter of how serious the switch/signal problems are. Plus, it's not a matter of where such a problem occurs. They should be truthful in every case, even if it's on the Rockaway Line. Also, it couldn't have been something else, as something more serious, i.e. a derailment, even a minor one, takes far more than an hour to fix.
