Electrically-powered railway wagons
The invention of an electrically-powered railway wagon was a precondition for the transport revolution that spurred the development of towns and industrial centres. It all started in 1874-1876, when Fyodor Pirotsky conducted a slew of experiments on transmitting electricity over a distance, with one rail serving as a direct conductor and the other, as a reverse conductor. An electric motor, located one kilometre from the power source, worked. A few years later, he conducted an experiment at a railway spur near Sestroretsk. There were 40 people in the wagon. The first electrified tram line was opened as late as 1881 in a Berlin suburb on the basis of designs by the Russian inventor.
