Bay Area Rapid Transit

BART is a fully-electrified rapid transit system serving the San Francisco Bay Area: five or six lines (mostly heavy rail, some short Diesel Light Rail and monorail segments) on 131.4 miles (211.5 km) of track with 50 stations (21 surface, 14 elevated, 15 subway) in five counties. Systemwide, there are approximately 32 miles (51 km) of aerial track; 70 miles (115 km) of track at grade and about 28 miles (45 km) of subway track. Most BART infrastructure is FTA-defined "heavy rail" tagged railway=subway, so BART is in California/Railroads' "Commuter" (passenger=suburban) section, as BART's systemwide geographic span is similar to other Commuter rail networks in California, including BART's newer infrastructure like Coliseum – Oakland International Airport (railway=monorail) line and BART to Antioch extension (railway=light_rail). All lines are tagged network=BART and the network-wide relation is 8477436 8477436.

BART Silicon Valley Phase II Extension Project intends to complete in 2030, adding four new stations to the Green and Orange lines: 28th Street / Little Portugal, Downtown San José, Diridon and Santa Clara in a largely subway alignment, achieving (with Caltrain correspondences at Diridon and Santa Clara) frequent Bay Area rail service that "rings the bay."

Tagging Conventions

Please follow rules on the newer public transport version 2 tagging conventions.

Route Master Relation

Key	Value	Comment	Recommendation
type	route_master	-	mandatory
route	subway, monorail, light_rail	BART=subway or Oakland Airport Connector=monorail or BART to Antioch extension=light_rail	mandatory
name	Line name	For example: Dublin/Pleasanton - Daly City Line	mandatory
operator	San Francisco Bay Area Rapid Transit District	-	mandatory
network	BART	-	mandatory
colour	Color	The color used on BART maps	recommended

These relations should have a member for each "normal" direction the line follows:

Element	Role	Recurrence?	Description
	none	two or more	type=route for each "normal" direction of the line, but excluding short turns when vehicles enter/leave service.

Route Relation

Key	Value	Comment	Recommendation
type	route	-	mandatory
route	subway, monorail, light_rail	Exactly as for the associated route master: BART=subway or Oakland Airport Connector=monorail or BART to Antioch extension=light_rail	mandatory
name	Destination Station	For example: Richmond, Millbrae, Dublin/Pleasanton	mandatory
from	Name of start terminal	-	mandatory
to	Name of destination terminal	-	mandatory
via	Name of major intermediate stop	-	recommended
description	Short description or route	Any major stations or stops along route	recommended
operator	San Francisco Bay Area Rapid Transit District	-	mandatory
network	BART	-	mandatory
colour	Color	Exactly as on the associated route master (duplicated for renderers that don't yet support route masters)	recommended

These relations should have a member for each way and stop that participates in this direction of service:

Element	Role	Recurrence?	Description
	none	one or more	the railways that are traversed in this direction of service, in the order they are traversed.
	stop	one or more	the stations (public_transport=stop_position + subway=yes +name=*) on the way

Stations

Each station is represented by several nodes/ways collected into a stop_area relation.

Key	Value	Comment	Recommendation
type	public_transport	-	mandatory
public_transport	stop_area	-	mandatory
name	Name of the station	For example: Lake Merritt	mandatory
network	BART	-	mandatory
operator	San Francisco Bay Area Rapid Transit District	-	mandatory
subway, monorail, light_rail	yes	The mode(s) that serve the station	optional

Each station should have at a minimum:

Element	Role	Recurrence?	Description
	none	one	A single member representing the station as a whole, usually a node placed at the center of the station (see below)
	stop	one or more	public_transport=stop_position + subway=yes/monorail=yes/light_rail=yes on the tracks
	platform	one or more	public_transport=platform + subway=yes/monorail=yes/light_rail=yes next to the tracks
	none	one or more	railway=subway_entrance for each station entrance

Each relation has a single member tagged with public_transport=station that includes most of the infomation specific to the station as a whole.

Key	Value	Comment	Recommendation
public_transport	station	-	mandatory
subway, monorail, light_rail	yes	The mode(s) that serve the station. At Millbrae, a different station co-located 25 meters away tagged train=yes represents an intermodal correspondence with Caltrain.	mandatory
name	Name of the station	For example: Lake Merritt	mandatory
alt_name	Other common names	Some stations use different spellings on signs inside and outside the stations, on maps, and on schedules. Include them here.	recommended
network	BART	-	mandatory
operator	San Francisco Bay Area Rapid Transit District	-	mandatory
railway	station	-	mandatory
station	subway, monorail, light_rail	Most BART stations are subway; the Oakland Airport Connector is monorail, and the Antioch extension is light_rail	mandatory
toilets	yes, no	-	recommended
wheelchair	yes, limited	All BART stations should be wheelchair accessible	recommended

Routes

(Note: BART is currently operating on a somewhat different route pattern than normal due to construction on the Transbay Tube. The routes currently mapped represent the current service pattern, whereas the table below represents the normal service pattern and is out of date.)
