Thomas
Davenport, American blacksmith and inventor, invented the first DC
electrical motor in 1834. A year later he invented a model electric
railway. He patented his electric railway that he called "Improvements in
propelling machinery by magnetism and electromagnetism" in 1837. The model
that he built of the electric train moved on a circular track 4 feet in
diameter; the power was supplied battery that used the rails as conductors. Granville Woods modified previous electric trains and made the trains more like the electric trains that we have today. He made an electric train without exposed wires, secondary batteries, or slotted causeway which was necessary for all electric trains before 1892 |
