The Chicago Surface Lines (CSL) was operator of the street railway system of Chicago, Illinois, from the years 1913 to 1947. The firm is a predecessor of today's publicly owned operator, the Chicago Transit Authority.
The first streetcars in Chicago were horse cars run by the Chicago City Railway Company and the North Chicago City Railway Company around 1858-1861. This method was slow and expensive, and the companies began substituting cable cars in the 1880s. Chicago City Railway was the first in (1881), and with the addition of the Chicago Passenger Railway (1883) and the West Chicago Street Railroad Company (1887), Chicago had the largest cable railway system in the world. The north and west side cable car systems were constructed by an investment syndicate under the direction of Charles Yerkes.
It was also in the 1880s that electric-powered "trolleys" first became practical. The Chicago companies hesitated at first to install these faster and more efficient systems because of their heavy investment in cable cars. But the smaller Illinois cities and the Calumet Electric Street Railway of the South Side built successful systems, causing the Chicago companies to feel themselves dropping behind. By the mid-1890s most of them had begun the conversion to electricity, which was completed in 1906.
The 1890s saw the consolidation of many of the Chicago companies, and this reorganization continued into the next century. In 1907 to 1909, the companies were granted franchises pursuant to various ordinances, under which the city reserved the right to purchase the systems. The Settlement Ordinance of 1907 imposed various operating requirements on two of the underlying companies, the Chicago City Railway Company and Chicago Railways, and established a new bureau, the Board of Supervising Engineers (Chicago Traction), a board of engineers and accountants with responsibilities for assuring compliance with the ordinances, and setting standards for equipment and construction.
Through Routes over the lines of several companies were instituted in 1910, and, for instance, resulted in joint service by the Chicago City Railway Company and Calumet and South Chicago Railway between downtown and 119th Street via Cottage Grove. There was also joint service operated by the South Chicago City Railway and the Hammond, Whiting, and East Chicago Electric Railway into Indiana, with each company collecting its own fare, which continued until the Hammond company converted to buses in 1940.
