Tubewatch (23)On your bike
With all the emphasis there's been from Mayor Ken on riding your bike to work, you might expect the tube to be more bicycle-friendly. But no. Only 113 tube stations have parking for bikes, and it's of very variable quality. My local station at Bow Road is one of the 113, apparently, although I don't ever remember seeing anyone risk leaving their two-wheeled pride and joy outside. So, if you can't leave your bike at the station, can you take it with you on the train? The answer is yes and no, depending on when and where you're going. Bicycles aren't allowed in the morning and evening rush hour, they're not allowed on escalators, and they're not allowed on any "deep level" tube lines. These restrictions lead to some strange anomalies, especially at the northwest tip of the Northern line. You can take your bike almost all the way from Golders Green to Edgware, which are five stations apart, but you have to get off and ride between Hendon Central and Colindale because the train goes through a short tunnel beneath the A41. Potential safety risk, apparently, should there be a major subterranean disaster (although I'm willing to bet that cycling along the Watford Way is far more dangerous than commuting underneath it).
Here's a very brief summary of where you can take your bike on the tube and where you can't.
Everywhere: Circle, District, East London, Hammersmith & City, Metropolitan
Somewhere: Bakerloo, Central, Jubilee, Piccadilly, Northern
Nowhere: Victoria, Waterloo & City (and DLR)
