Time corridor

A time corridor, also called a spacetime-induction channel, was a form of time travel in which a wormhole was created through the Time Vortex. It was generally considered less advanced than other time travel technologies such as TARDISes.

Time corridors were primarily used by the Daleks. Despite being described as less advanced than other Time technology, Time corridors seem to be easily capable of dragging a TARDIS off course to a specific location. (DW: The Evil of the Daleks, Resurrection of the Daleks, Remembrance of the Daleks)

Time corridor technology was first used by the Daleks near the beginning of the Great Civil War. (DW: The Evil of the Daleks) After the end of the civil war and the defeat of the Humanised Daleks, the Emperor Dalek decided that the Daleks, in order to succeed in their conquests, would have to change history, thus time travel was put into greater use by the race. (REF: Doctor Who: The Dalek Handbook)

In order to complete a corridor, the Daleks built time conduits that would serve as the ends of the corridor. If the conduit on a planet was destroyed, the Daleks would no longer be able to reach it via the time corridor. (BFA: The Mutant Phase)

The Daleks used a time corridors as a link between themselves and Earth in 1984. There they had deposited samples of the Movellan virus that they would later need.

Turlough accidentally travelled through the corridor and so the Doctor followed him in his TARDIS. Both the Daleks and Lytton's men used the corridor numerous times. (DW: Resurrection of the Daleks)

The Dalek paradigm escaped through a time corridor after their plan to destroy Earth failed. (DW: Victory of the Daleks)

In emergencies craft travelling within a time corridor could deploy an escape time corridor which could latch onto familial technology. (BFA: The Time of the Daleks)
