Legends among transport enthusiasts, Geoff Marshall and Vicki Pipe are making a special appearance at London Transport Museum in February.
The one-off show is aimed at younger London Underground lovers, discussing the pair's book, The London Underground: 50 Things to See & Do.
Geoff and Vicki will describe their unusual journeys on the Underground network, tell intriguing facts, and reveal unique and interactive games to play and sights to see, next time you're on the tube.
The one-hour talk is followed by a book signing.
Here's a video Geoff and Vicki made especially for us, while on their All The Stations adventure:
