Possible Consequences of Operating The Emergency Brake
Putting the engineer's brake handle into the emergency position may also:
- Shut off traction power
- On an electric train, drop the pantograph if the power supply is overhead-wire traction current, or raise the pickup shoes where the supply is third-rail traction current
- Disable dynamic braking
- Prevent the brakes from being released until the train has stopped
- Connect the brake wires to ground, to prevent a "false-feed" voltage from releasing the brakes
- Send an emergency radio signal, if the brake handle has been in the emergency position for over 30 seconds

Famous quotes containing the words emergency brake, consequences, operating and/or emergency:
“In this country, you never pull the emergency brake, even when there is an emergency. It is imperative that the trains run on schedule.”
—Friedrich Dürrenmatt (1921–1990)
“There is a delicate balance of putting yourself last and not being a doormat and thinking of yourself first and not coming off as selfish, arrogant, or bossy. We spend the majority of our lives attempting to perfect this balance. When we are successful, we have many close, healthy relationships. When we are unsuccessful, we suffer the natural consequences of damaged and sometimes broken relationships. Children are just beginning their journey on this important life lesson.”
—Cindy L. Teachey. “Building Lifelong Relationships—School Age Programs at Work,” Child Care Exchange (January 1994)
“Go on then in doing with your pen what in other times was done with the sword; shew that reformation is more practicable by operating on the mind than on the body of man.”
—Thomas Jefferson (1743–1826)
“War-making is one of the few activities that people are not supposed to view “realistically”; that is, with an eye to expense and practical outcome. In all-out war, expenditure is all-out, unprudent—war being defined as an emergency in which no sacrifice is excessive.”
—Susan Sontag (b. 1933)
