Photography on London Underground:

If you want to take photos of London Underground, no special authorisation is required in public access locations.   Do not use flash when photographing trains or stations.  Do not locate yourself in a place of risk. 

Do not use flash as you can blind the drivers.

Incidentally the Underground will be 150 years old in 2012.

If you want to Know 150 great things about the Underground go here 

The London Transport Museum in Convent garden is also worth a visit, and you can use their Tube driving simulators. Great fun.

We will be going to Temple underground station.

Take a Westbound district line train (ie to Ealing, Richmond or Wimbledon).
