This is mostly a northeastern thing but most all the trains that run in and around Grand Central Station, Albany and Boston run with cab signals. That's how some of the trains are able to run 140 mph. With out cab signals your not to exceed 79 mph. They started installing them around 1975. They're displayed in white only on both sides of the cab. (in example) If an advanced approach is displayed you have 7 seconds to make a brake application. If your not down to the signal's speed 45 mph in 15 seconds the train control part of the cab signal will make the brake application until the speed is achieved and so on.
