The Station (unproduced TV story)
From Tardis Wiki, the free Doctor Who reference
The Station was to have been the second of four Halloween specials for The Sarah Jane Adventures, but due to the death of Elisabeth Sladen was never produced. Like the other Halloween specials it would have been a live 2011 broadcast.
It would have seen Luke, Clyde, Rani and Sky transported back to the years 1911 and 1934.
It would have been succeeded by an unnamed Halloween special, again by Clayton Hickman. (DWMSE 32)
