T (New York City Subway service)

The T Second Avenue Local is a prospective rapid transit service in the B Division of the New York City Subway. Its proposed route bullet will be turquoise, a currently unused color, since it will run over planned Second Avenue Line in Manhattan.

The Second Avenue Subway is under construction, with the first phase, running from 63rd to 96th Streets, planned for completion in December 2016. The T designation will not be used until the third phase opens from Houston to 63rd Streets. The third phase is not funded or scheduled.

History

T was previously used for a service on the BMT West End Line, originally BMT 3. It was discontinued in 1967, but a shuttle, designated TT, continued into 1968, when it was replaced by the B train via Sixth Avenue in Manhattan. With the closing of the Manhattan Bridge's north side in 2001, the B in Brooklyn was replaced by the W via Broadway. In 2004, the Manhattan Bridge reopened for subway service and the W was replaced by the D via Sixth Avenue.T currently appears on R32 rollsigns as a black letter on a white circle.

Countdown

A countdown is a sequence of backward counting to indicate the time remaining before an event is scheduled to occur. NASA commonly employs the term "T-minus" during the preparation for and anticipation of a rocket launch, and even "E-minus" for events that involve spacecraft that are already in space, where the "T" could stand for "Test" or "Time", and the "E" stands for "Encounter", as with a comet or some other space object. Other events for which countdowns are commonly used include the detonation of an explosive, the start of a race, the start of the New Year, or any anxiously anticipated event. An early use of a countdown once signaled the start of a Cambridge University rowing race. The first known association with rockets was in the 1929 German science fiction movie Die Frau im Mond (English: Woman in the Moon) written by Thea von Harbou and directed by Fritz Lang in an attempt to increase the drama of the launch sequence of the story's lunar-bound rocket.

Rocketry

A countdown is a carefully devised set of procedures ending with the ignition of a rocket's engine. Depending on the type of vehicle used, countdowns can start from 72 to 96 hours before launch time.
