Dalek time machine (The Chase)

The first Dalek time machine was roughly comparable in abilities to a Time Lord TARDIS. It was dimensionally transcendent and created for the express purpose of chasing the First Doctor through time and space. It enabled the Doctor's companions Ian Chesterton and Barbara Wright to return home. At first the Doctor refused, insisting it was too dangerous but he changed his mind. The Doctor instructed the pair to set the ship for self-destruction after it had transported them to London on 26 June 1965. (TV: The Chase; PROSE: The Time Travellers)
