To quickly assess the difficulty of the text, read a short excerpt:
A glance at the control step and at the ammeter gives the running speed. In alternating-current performance the speed for local and express trains is nominally 60 m. P. H. , but the writer has repeatedly observed speeds up to 72 miles per hour when lost time was being regained. Control step No. 6 is commonly used and, with a 6-coach train, about 1000 amperes, corresponding to 62 m. P. H. , is an ordinary reading. In direct-current performance, 30 m. P. H. Is the speed allowed by the New York Ce...ntral rules, between the Grand Central terminal at Forty- fourth Street and Ninetieth Street, or in passing any stat'on; and 45 m. P. H. Is the maximum speed allowed in the direct-current zone. Con- trol step marked No. 2 is used for maximum speed, and the meter reading is commonly 1200 to 1100 amperes. The full speed for which the motors were designed is not used, due to the speed restrictions imposed. PERFORMANCE CHARACTERISTICS OF PASSENGER LOCOMOTIVE. Current amperes. Power factor. Speed m. P.
