{{Quote|Good morning and welcome to the Black Mesa Transit System. This automated train is provided for the security and convenience of the Black Mesa Research Facility personnel.|Black Mesa Transit System announcement|Half-Life|FileC0a0 tr gmorn.ogg}}

The '''Black Mesa Transit System''' is a transit system featured in ''Half-Life'' and Half-Life expansions|its expansions.

The Black Mesa Transit System is the extensive monorail network linking the many different CategoryBlack Mesa Sectors|Sectors of the Black Mesa Research Facility. The Transit System is the primary form of transportation throughout the facility, which uses the WikipediaMonorail|monorail system, a transportation system based on a single beam. Provided for the security, comfort and convenience of the Black Mesa personnel, residents and visitors,''''Half-Life Blue Shift.html">Half-Life''''Half-Life Blue Shift'' it is managed by the Black Mesa Transit Authority.

*Each train consists of a single monorail car driven automatically. It includes seats, a wheelchair space, windows, speakers and an electric door.

*The network is equipped with an Black Mesa Transit System/Quotes|announcement system which is mounted on the trams to give general information about the facility and mention each stop, with a prerecorded female voice. It is voiced by Kathy Levin, who also provided the voice of Gina Cross and her Holographic Assistant counterpart, suggesting Cross herself might have recorded it.

*The protagonists of the game use the Transit System before and after the Black Mesa Incident to get around the facility. Gordon Freeman and Barney Calhoun for example ride a tram to work from their dormitories shortly before the incident. Adrian Shephard also briefly hitches a ride on a damaged tram before being left behind by the USMC.

*The Black Mesa Transit System should not be confused with Sector E's Sector E Transport|Materials Transport, the dilapidated freight monorail network.

==Lines and other areas==
FileTram map 01.png|200px|Black Mesa Transit System map.|right|thumb

The network is divided in four colored lines linking to particular areas of the seven main Sectors and other areas, and sub-lines. Each line serves three or four areas.

===Main colored lines===
====Red Line====
*Level 3 Dormitories
*Sector G - Hydro Electric
*Sector C 3 Medium Security Facilities and H-E Particle Labs|Area 3 Medium Security Facilities
*Freight Yard

====Blue Line====
*Sector C
*Sector B - Coolant Reserve
*Area 9 Central Transit Hub

====Green Line====
*Level 1 Main Facility Entrance
*Sector E - Biodome Complex
*Area 7 Recreational Facilities
*Sector A

====Yellow Line====
*Sector D - Sector D Center|Administration
*High Altitude Launch Center
*Sector F

Each Sector has apparently its line, a sub-line to the overall network. Only three are seen/mentioned during the games

====Sector B Line====
A medium-security line connected to the Area 9 Security Checkpoint.

====Sector C Line====

A medium-security line, it is connected to Area 9 Security Checkpoint, Level 3 Dormitories, Area 3 Medium Security Facilities, and Test Labs. Gordon Freeman and Barney Calhoun take it to reach their respective workplaces on the day of the Black Mesa Incident, Barney from Area 9 Security Checkpoint, Gordon from Level 3 Dormitories.''Half-Life'' Before the Test Labs stop, the line passes beside another, leading to Level A of Sector E Subsurface Transport, and taken by Adrian Shephard after leaving the ''Half-Life Opposing Force.html">Infirmary.''Half-Life Opposing Force''

====Sector E Line====
Connected to Area 9 Security Checkpoint, it is located below the Sector B Line and above the Sector C Line. Its directions are unknown.

=====Sector E Subsurface Transport=====
Level A of this Black Mesa Transit System section can be accessed from Sector C Line, where the G-Man is first seen in ''Half-Life'', and leads to an unnamed area where the first Shock Trooper and zombie security guards are encountered.

====Central Transit Hub====
{{Main|Central Transit Hub}}

The Central Transit Hub is only mentioned and never actually visited. It is apparently the only Transit System station where high-security trains can be boarded. Area 9 Central Transit Hub is also the original final destination of the tram used by Barney Calhoun before it is rerouted to the Sector C Line. It is connected to the Blue Line of the Black Mesa Transit System.FileTram map 01.png|Black Mesa Transit System map The Central Transit Hub was originally intended to be visited in ''Half-Life Decay'', but the mission was cut from the final game.
