Page 88 - Swung vertically in a circle at arm's length across the track, when the train is running.
Page 62 - In making a service stop with a passenger train, always release the brakes a short distance before coming to a dead stop, except on heavy grades, to prevent shocks at the instant of stopping. Even on moderate grades, it is best to do this, and then, after release, to apply brakes lightly, to prevent the train starting, so that when ready to start, the release will take place quickly.

Page 30 - in which P = working pressure in pounds per square inch, t — thickness of flue in inches, L = length in feet and D = outside diameter in inches. In this formula L is not to exceed 8 feet. In case the flue is made with rings riveted to the flue, L is taken as the distance between rings. What is the allowable pressure on a furnace flue 6 feet long, 42 inches in diameter and inch thick? p...
Page 105 - Schedule meeting or passing stations are indicated by figures in full-faced type. Both the arriving and leaving time of a train are in fullfaced type when both are meeting or passing times, or when one or more trains are to meet or pass it between those times.
