There is also just a whole bunch of random photos and people in there too.

Leinster Gardens

The reason for the trip to London was to see all the things listed above, but mainly to see the Leinster Gardens vent. The original underground in London was a steam railway and the engines used to collect their poisonous gases in a tank, stop at the vents and release them and continue the journey afterwards.

The most known 'fake house' is the one at Leinster Gardens. The front of the house looks normal mostly, but a trip around the back tells a different story and you can see the tracks. I also managed to get a photo with a live modern day tube train going through as well.

While on the tube found two more vents but I've yet to determine their location. I will find them though - it may just take a little time.
