This weekend is one of the rare days the London Transport Museum's depot at Acton Town is open.
Some days you see a spot you've been to hundreds of times at a slightly different angle. I came out of the tube station at Tower Hill to catch the last of the afternoon light. I think I've always walked the other side of the underground side as I haven't noticed this view before.
Tottenahm Court tube station is about to undergo the next stage of redevelopment as part of the new cross rail work. The tiling created in the last renovation may be destroyed in the process.
The Strand station opened in 1907 and closed in 1994. It was renamed Aldwych in 1915 as there was already a Strand station (what is now Charing Cross). In 1974 the Strand was renamed Charing Cross. All of this was to avoid confusion.
Dating from 1874 Liverpool Street Station sees 123 million visitors pass through each year.
The East Finchley station (Northern Line) was rebuilt in art deco style in the 1930's. 
Although mid month is subway day, today I am showing you an overground station. Battersea Park station on a cold afternoon. Does anyone know what the big blue/grey tank is?
Black Friars station opened in 1870. One of the busiest, it has overground trains, the Thames link, and the tube all running through it. Closed for 3 years for major work on the Thames Link -the planned reopening is late 2011. 
There are a number of closed underground stations in London, many with interesting stories to tell. This closed station is in York Way (at the back of Kings Cross).
Drama at Leytonstone. Today you have it all. Jealousy, fear and obsession.
Baker St station opened in 1863 on the first underground in the world, possibly making it the oldest underground station anywhere.
At least twice a day millions race underground to these stylish bunkers where they pack themselves into these equally stylish pods in a manner befitting a tinned sardine. No eye contact, please don't talk. Best of all please don't expect to get anywhere on time. Weekends. I suggest you walk. Can you spot where the millions in refurbishment has been spent?
When you pop up from the tube it can be difficult to find your bearings. Some of the tube stations have really helpful maps that help you work out where you are.
Russel Square tube is one of my favourites. Built in 1906 it has lovely tile work and those great lights outside. It services the Piccadilly line which as I have said before is one of the deepest. If the lifts aren't working that means a climb of 177 steps. You get out here to go to the British Museum.
It is also skywatch friday with beautiful skies around the world. 
Tottenham Court Road tube stop is at the corner of Tottenham Court Road, Oxford St and Charing Cross Road. Books, technology and shopping depending which road you take.
While you are viewing the underground I will be flying back to London.
Russell Square platform on the Piccadilly line. It's one of the smaller stations, opened in 1906 so has lovely old green and white tiles. The Piccadilly line is a very deep line, at the station you either take the elevators or if you are feeling very fit, the 175 stairs. Although a sign warns you that taking the stairs is dangerous to your health. I'll let you decide on that one.
