A time corridor is a form of time travel in which a wormhole is 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. (DW: The Evil of the Daleks, Resurrection of the Daleks, Remembrance of the Daleks, 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)
