[2] These were merged in 1902 to form the Maple Avenue and East Lake Park Line.

This segment of the route closely followed the Arroyo Seco, ATSF main line, Los Angeles Terminal Pasadena branch, and Los Angeles and Pasadena Railway, stopping quite close to Highland Park Station.

At the northeast end, an extension was built along Eagle Rock Avenue to Buena Vista Terrace.

In 1955, the entire northeastern segment of the route was abandoned and the W line then ran east via Broadway to Lincoln Park Avenue.

The entire route was abandoned a year later on November 18, 1956, with substitute bus service becoming the 12 Line.
