St. Paul's tube station

St. Paul's was a tube station that Jamie McCrimmon and Driver Evans stumbled across after they escaped the Yeti's Web at Monument. Evans noted this meant they had escaped the Circle line and were now on the Central line.

It was here that Evans, fancying some chocolate, tried a platform vending machine selling bars of Camfield's Fairy Milk Chocolate without inserting any money and discovered, to his surprise, there was a bar in the machine's open compartment. (TV: The Web of Fear)

Behind the scenes

 * Unremarked in Web was the fact that St. Paul's was, of course, proximate to St Paul's Cathedral.
