"Thomas Davenport, a poor blacksmith of Brandon, Vt., constructed what might be termed the first electric railway. The invention was crude and of little practical value, but the idea was there. In 1835 he exhibited in Springfield, Massachusetts, a small model electric engine running upon a circular track, the circuit being furnished by primary batteries carried in the car. Three years later, Robert Davidson, of Aberdeen, Scotland, began his experiments in this direction. ... He constructed quite a powerful motor, which was mounted upon a truck. Forty battery cells, carried on the car, furnished power to propel the motor. The battery elements were composed of amalgamated zinc and iron plates, the exciting liquid being dilute sulphuric acid. This locomotive was run successfully on several steam railroads in Scotland, the speed attained was four miles an hour, but this machine was afterwards destroyed by some malicious person or persons while it was being taken home to Aberdeen. In 1849 Moses Farmer exhibited an electric engine which drew a small car containing two persons. In 1851, Dr. Charles Grafton Page, of Salem, Massachusetts, perfected an electric engine of considerable power. On April 29 of that year the engine was attached to a car and a trip was made from Washington to Bladensburg, over the Baltimore and Ohio Railroad track. The highest speed attained was nineteen miles an hour. The electric power was furnished by one hundred Grove cells carried on the engine. ... The same year, Thomas Hall, of Boston, Mass., built a small electric locomotive called the Volta. The current was furnished by two Grove battery cells which were conducted to the rails, thence through the wheels of the locomotive to the motor. This was the first instance of the current being supplied to the motor on a locomotive from a stationary source. It was exhibited at the Charitable Mechanics fair by him in 1860. ... In 1879, Messrs. Siemen and Halske, of Berlin, constructed and operated an electric railway at the Industrial Exposition. A third rail placed in the centre of the two outer rails, supplied the current, which was taken up into the motor through a sliding contact under the locomotive. ... In 1880 Thomas A. Edison constructed an experimental road near his laboratory in Menlo Park, N. J. The power from the locomotive was transferred to the car by belts running to and from the shafts of each. The current was taken from and returned through the rails. Early in the year of 1881 the Lichterfelde, Germany, electric railway was put into operation. It is a third rail system and is still running at the present time. This may be said to be the first commercial electric railway constructed. In 1883 the Daft Electric Company equipped and operated quite successfully an electric system on the Saratoga & Mt.
