Following the Great Merger of 1911, control of the route returned to the Los Angeles Railway. They extended the route north and east along Evergreen and Wabash Avenues to the city limits in 1915.[3]
Expansion and later removal (1911–1949)
The line was rerouted on May 9, 1920[4] and given the letter designation B the following year.[5][6] Tracks on 9th Street were taken over by the N Line and the remaining service was merged with the Ascot Line, a previously unconnected route which ran by way of Main Street, 12th Street, Hooper Avenue, a private right-of-way alongside the Santa Monica Air Line, and Ascot Avenue.[7][3] (A section of this, between Adams Boulevard and 41st Street, has since been filled in.)[citation needed]
In 1924, rush hour trips were extended northeast along the newly built Harrison Street (later Ramona Boulevard, and later still City Terrace Drive) to Alma Street in East Los Angeles.[3] Completion of the Macy Street Bridge in April 1926 allowed through-routing to Brooklyn Heights.[8] The line began serving Union Station upon its opening in 1939.[9] The final extension of the line was north to City Terrace and Miller Street on March 13, 1931.[3][10] Streetcars were replaced with trolleybuses on December 5, 1948.[11]
