A map of the turbolift system aboard the refit Template:ShipClass USS Enterprise
View of a turbolift from the outside
Located on board most starships and space stations, the turbolift provides both vertical and horizontal transportation for personnel through turboshafts between key sections of a ship. In the 2270s, the turbolift's tactile interface was succeeded by voice command operation.
Turbolift specifications
The turbolift personnel transport system is a network of inductively powered transport tubes allowing the volume of the ship to be traversed in a high-speed manner.
Many Starfleet turbolifts are comprised of a lightweight duranium-composite framework supporting a cylindrical personnel cab constructed from microfoamed duranium sheeting. Mounted longitudinally along the exterior of the cab are three linear induction motors that provides the motive force. Electromagnetic conduits located along the length of each turboshaft provide power to these motors, allowing accelerations up to ten meters per second squared. (citation needed • edit) To counter such high acceleration speeds, an inertial dampener is usually installed at the base of the cab to provide crew comfort, eliminating some (although not all) of the acceleration effects. In some Starfleet vessels, a plan of the ship is displayed along the back of the turbolift, allowing for directional assistance in the absence of computer access.
Template:ShipClass starships needed only a button to be pressed to specify which deck to travel to. (ENT: "Cold Front") Incorporated in the design of Template:ShipClass turbolifts were small handles on the interior, allowing for transport without the use of voice commands. At some point, it became necessary to use both the handle and to submit a voice command on board Constitution-class ships. (DS9: "Trials and Tribble-ations") Later refits phased out any analog interfaces and featured auditory receivers allowing passengers to use voice commands to direct the turbolift. Upon receipt of the voice command, the command queries the network, allowing for computation of the most optimal route to the destination. Such routes factor in the presence of other turbolifts already in operation. The auditory receivers also automatically scan for voiceprint authentication, allowing for select personnel access to restricted areas. Turbolifts from the 23rd century also featured communication panels to allow communication with other sections of the ship without the need for a communicator. (TOS: "Elaan of Troyius")
While most starship turbolifts were enclosed, some turbolifts remained open when at rest, in the style of an elevator built in the early-to-mid-20th century. The Cardassians built such a turbolift on Terok Nor when it was in operation, and it was still in use by Starfleet on the renamed Deep Space 9. Once this turbolift became activated, it became enclosed as a precautionary measure. These turbolifts' positioning mechanisms were powered by multi-phase alternating current. In ships and stations that contain turbolift doors that remain closed while not in use, the doors will often be unresponsive in low or no power situations.
With Voyager at low power, Janeway is forced to open the turbolift doors by hand.
In a Template:ShipClass starship, turbolifts are regulated by turbolift control and an average of ten turbolift cars are in service at any one time. Some peak usage times, such as change-of-shift, can call for a doubling of the turbolift cars with only a 22% decrease in efficiency. The reason this is possible is because the turboshaft network is designed with the specific purpose of allowing multi-access loops and thus permitting a flexible route for each turbolift car. (citation needed • edit)
When battle stations are ordered, all turbolift cars may be subjected to deactivation pending the authorization of the commanding officer. In such cases, personnel are still free to move about the ship via a network of vertical ladders and Jefferies tubes.
While docked at a Starbase, the turboelevator network is connected to the network of the adjacent Starbase, allowing for easy passage without the use of an umbilical dock. This is accomplished through a connection point located at the upper terminus of turboshaft two, leading from the main bridge. When linked, turbolifts cars may travel freely between the ship and areas of the Starbase.

Turbolift incidents
In 2287, after the construction of the new USS Enterprise-A, many systems were still nonfunctional, including the warp drive. After shore leave, when Kirk entered the main bridge with Spock and McCoy, Kirk was annoyed by the turbolift only opening partially. (Star Trek V: The Final Frontier)
Lwaxana Troi and Odo inside a turbolift in 2369
In 2365, when the USS Enterprise-D scanned the logs from the USS Yamato, they contracted a computer virus, which severely affected all critical systems aboard the ship. One of these systems were the turbolifts, and a malfunction resulting in highly increased acceleration rates and tremendous direction shifts, injuring Lieutenant Geordi La Forge inside, practically throwing him onto the bridge. (TNG: "Contagion")
In 2368, a metal parasite infested the Enterprise-D when it destroyed an asteroid about to collide with a planet. This parasite began to ingest the nitrium from all critical systems. One of these systems was the turbolifts, as the circuitry was being broken down as Captain Picard and Lieutenant Commander Data were still inside, although no incident seemed to occur. (TNG: "Cost of Living")
Also in 2368, a collection of quantum filaments collided with the Enterprise-D, disabling power to many of the main systems, including life support, main engines, and computer control. At this time, Picard and some children were in a turbolift, and Picard decided to climb the emergency shaft in case the unstable turbolift fell in the shaft. Using a makeshift rope made from optical cable, Picard and the children escaped the doomed turbolift and climbed to the upper decks. (TNG: "Disaster")
In 2369 Constable Odo and Ambassador Lwaxana Troi were trapped in a turbolift for several hours after an alien probe, later called "Pup" by Miles O'Brien, damaged several of the station's systems. Kira Nerys informed Odo not to shape-shift his way out through the turboshaft, as Cardassian turbolifts have exposed multi-phase alternating current running through the positioning mechanism. (DS9: "The Forsaken")
In 2372, the Cardassian terrorist group the True Way sabotaged one of Deep Space 9's turbolifts, as part of a scheme to assassinate Bajoran First Minister Shakaar Edon. (DS9: "Crossfire")
