Originally, the railroad's Chicago terminus was the 52nd Avenue station that it shared with the Garfield Park elevated railroad line of the Metropolitan West Side Elevated Railroad, and where passengers transferred between interurban and elevated trains. Beginning on March 11, 1905, the interurban began operating over the Metropolitan's "L" tracks, allowing AE&C trains to directly serve downtown Chicago. At the same time, the Metropolitan's Garfield Park service was extended west of 52nd Avenue, replacing the AE&C as the provider of local service over the interurban's surface-level trackage as far west as Desplaines Avenue in Forest Park. The interurban's trains terminated at the stub-ended Wells Street Terminal, adjacent to the Loop elevated. The interurban continued to use the "L" tracks through the years of Chicago Rapid Transit Company (CRT) ownership and into the Chicago Transit Authority (CTA) era.
