{{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 Announcement System|Half-Life}}

The '''Black Mesa Transit System''', or '''tram''', 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 Transit System is prominently featured in ''Half-Life'' and its CategoryHalf-Life Expansions|expansions. Black Mesa employees use it to travel from their dormitories to their workplace, do their laundry, entertain themselves in recreation areas, or eat in food courts.

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. 

After the Black Mesa Incident, the majority of the Transit System was in shambles, thus preventing the majority of the personnel from using it, like Gordon Freeman. 

The Black Mesa Transit System should not be confused with the Sector E 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 the seven main Sectors, as well as 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 Test Labs 3 Medium Security Facilities and High-Energy Particle Labs|Area 3 Medium Security Facilities
*Freight Yard

====Blue Line====

*Sector C Test Labs
*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 Training Facility

====Yellow Line====

*Sector D Administration
*High Altitude Launch Center
*Sector F Lambda Complex


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

====Sector B Line====
FileTopside dorms.jpg|thumb|200px|left|Sector B Line passing by through the Area 8 Topside Dormitories.

A medium-security line where can be found the Area 9 Security Checkpoint, it is the line taken by Barney Calhoun from Area 8 Topside Dormitories through the East Personnel Entrance, and leading to Area 9 Central Transit Hub. Along Sector B Line can be seen a fast food outlet, a lab, and a lavomat.

=====East Personnel Entrance=====

Connects Area 8 Topside Dormitories to the rest of the facility through the Transit System. Above it floats an FileBlack Mesa orange flag.svg|orange flag of Black Mesa. Its name suggests there are other such entrances.

=====Area 9 Security Checkpoint=====

Likely located not far from Area 9 Central Transit Hub, Area 9 Security Checkpoint is first seen during Barney Calhoun's tram ride at the start of ''Blue Shift''. There Barney Calhoun leaves the line he took at Area 8 Topside Dormitories to the Sector C Line. Area 9 Security Checkpoint apparently acts as one of the many transit security checkpoints throughout the Transit System. Trams that pass through that checkpoint can be rerouted to the Sector B, C and E Lines.

====Sector C Line====
FileBa security10009.jpg|Gordon Freeman riding along the Sector C Line.|thumb|200px|right

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.


====Area 9 Central Transit Hub====

Also named "Area 9 Transit Hub", Area 9 Central Transit Hub''Half-Life'' 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 through Sector B Line, before it is rerouted to 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

==Behind the scenes==

''Half-Life'' and ''Blue Shift'' start on a tram that the player cannot leave before reaching the intended destination. This obligatory ride is mostly used to slowly immerse the player into the universe. The path from the City 17 Trainstation to Kleiner's Lab in ''Half-Life 2'' has a similar purpose, although in that case it was made so that the story would unfold at the player's own speed rather than on a fixed rail.''Half-Life 2 Raising the Bar''
