Underground

This is the tenth episode of Season 14.
==Story==
A Northern line train goes missing after using the Kennington Loop which leads to the Doctor and Elise going underground to discover the truth that a time portal back to 1893 is responsible for this problem. Only the person behind the time tunnel is a man who calls himself the Wanderer.

==Behind The Scenes==
Something Doctor Who has never done is look back at cultural icons like the London Underground properly and this would work well as a good historical story to learn about the genesis of such an iconic piece of public transport in British rail history. And whilst it would be focusing primarily on the southern part of the northern line, a lot of the content would be cgi animated given how different the London landscape now is to 1893.***
