Karlsbrücke
In the early 20th century, a monopoly was formed to provide transportation in the city. It began to electrify the horse tram and soon the Otlet Prague trams came under the control of competitors of the electric enterprises. As the monopoly grew, it took over the tracks of the rest of its private competitors. The last private track, the work of František Křižík, was transferred to the city by the year of 1907. In 1905, the electrification works were finished. Even the last horse tram route through the Charles Bridge was electrified (also a project of František Křižík). The tram route through the Charles Bridge operated until 1908.
