Locomotive Engine Running and Management

by Angus Sinclair

THROTTLE DISCONNECTED.

Any accident to the throttle-valve or its attachments, which deprives the engineer of power to shut off steam, is very dangerous, and calls for prompt action. Lose no time in reducing the head of steam to fifty or sixty pounds, or to the pressure where the engine can easily be managed with the reverse-lever.

With the aid of a power-brake, an engineer can get along fairly with a light train, after an accident has happened which prevents the closing of the steam from the cylinders; but constant vigilance and thoughtful labor are needed.
