, barely missing several workers and causing damage to buildings on the street. Subway construction was delayed during the investigation and repairs of the sinkhole. The contractor on that segment project was replaced, and because of the perceived mismanagement of Red Line construction, in 1998 voters banned the use of existing sales taxes for subway tunnelling.

Construction of MOS-3, by comparison, proceeded with relatively few issues. Tunnelling from North Hollywood for the subway started in 1995. Workers dug under the

and west from North Hollywood towards the
Warner Center transit hub in the San Fernando Valley. Barred from subway tunnelling, Metro turned to other types of mass transit. In the San Fernando Valley, residents passed a law in 1991 mandating that any rail line in the area be built underground, so Metro built a busway (now the
G Line) from North Hollywood to Warner Center, which opened on October 29, 2005. East of Union Station, Metro built a light rail line with at-grade and underground segments to East Los Angeles, now part of the
E Line, which opened on November 15, 2009.
In 2020, Metro renamed all of its lines using letters and colors, with the Red Line becoming the B Line (retaining the red color in its service bullet) and the Purple Line becoming the D Line.
Operations
On Metro Rail's internal timetables, the B Line is called line 802.
Maintenance
The B Line operates out of the Division 20 Yard (Santa Fe Yard), located at 320 South Santa Fe Avenue in Downtown Los Angeles. This yard stores the fleet used on the B and D Lines, and where heavy maintenance is performed. Cars reach this yard by continuing past Union Station, making a right turn and surfacing at the Eastern terminus of Ducommun Street. They then travel south to 1st Street, through a washing station, and enter the yard.
Rolling stock

Potential future extensions
Extension to Arts District
In 2010, at the request of L.A. City Councilman
Tom LaBonge, Metro staff studied the possibility of adding a station along the west bank of the
Los Angeles River
The Los Angeles River (), historically known as by the Tongva and the by the Spanish, is a major river in Los Angeles County, California. Its headwaters are in the Simi Hills and Santa Susana Mountains, and it flows nearly from Canoga Park ...
to 6th Street and Santa Fe Avenue. The study concluded that such an extension, completed at-grade along Metro-owned right-of-way, could be completed for as little as $90 million.
The study suggested an alternative station at the Division 20 Yard north of 4th Street and Santa Fe Avenue. This station would be closer to the residential population of the Arts District. As new turnback tracks will need to be built as part of the
D Line Extension (to allow shorter headways), this Arts District extension could possibly be partially completed as part of the Purple Line Extension project, lowering the incremental cost of the station while increasing its usability.
Extensions to the South
One of the proposals for the Vermont Transit Corridor being considered by Metro would extend a subway line from Wilshire/Vermont station down Vermont Avenue to 120th Street. Metro is also considering other types of mass transit for the line, including light rail and busway options.
