电气化铁路发展史

1.2 Early Experiments
(1) The first experimental electric railway in the world is attributed to Thomas Davenport, a blacksmith of Vermont, U.S.A., who exhibited a small railway operated by a miniature electric motor in 1835. 利用电磁铁制作了往复 式电动机，驱动车辆在轨道上行使，供游人参观。
(4) In 1847, also, Professor Farmer operated an electric car carrying two passengers at Dover, New Hampshire. Between that year and 1858 numerous experiments were carried out in various parts of the world, in which small rail- and roadcars were operated by means of electric storage batteries.
1.3 Invention of DC Dynamo and Motor
(1) In 1858 Pacinotte invented the continuous current dynamo. This invention was followed by the development of self-energizing field magnets by three Englishmen - Wheatstone, Varley, and Ladd, by the German engineer Siemens, and also by the American inventor, Professor Farmer. 1861年 Siemens制作了直流发电机。
(2) This group of men, working quite independently, achieved the same result almost simultaneously in the years 1866-7. Three years later a French scientist, Gramme, produced the first practical direct current dynamo, with self-exciting field magnets and an armature wound with wire in the form of a continuous ring. Later the ring type of armature gave place to the drum armatures designed by Van Alteneck and Professor Rowland.
(2) The electric locomotive and electric motor coach(电动客车) may be regarded as natural developments that have followed steam traction. Their emergence is the result of social demand on the rapid train services for the new built-up suburban areas spreading in all directions round large cities.
(2) A Scotsman(苏格兰人) named Robert Davidson built in 1838 an electric locomotive that attained a speed of four miles an hour.
(3) In England a patent was granted in 1840 for the use of rails as conductors of electric current, and similar American patents were issued to Lilley and Colten in 1847.

1.1 Social Demand
(1) The scientific wonder of today is the commonplace of tomorrow. This is certainly true of electricity‘s application to our modern needs. The little electric models constructed by early inventors have developed into the electric expresses(快车) and giant electric freight engines, in use throughout the world at the present time.
(5) 1850年，美国的霍尔利用地面上的电池作电源驱动车辆 运行。
(6) It was on April 29, 1851, that a small road-car, built by Professor Page of the Smithsonian Institute, attained a speed of nineteen miles an hour near Washington - to the utter destruction of the batteries.
