This should throw up some interesting things

- on the linear map of the Hammersmith and City line
Paddington and Edgware Road appear twice

The platform descriptors at Edgware Road should be interesting.
"Terminates Here," "Edgware Road via Aldgate," "Hammersmith" and
"Hammersmith via Aldgate"

- Three lines to choose from between Gloucester Road and Hammersmith,
two stops on Piccadilly, three on the district, or 31 on the
Hammersmith and City

Not to mention that all the way from Gloucester Road to Tower Hill,
there are trains to Hammersmith in both directions, and the one
advertised as going there is most likely the slower one.

Similarly, the fastest way to Hammersmith from Bayswater, Notting Hill
Gate, and High Street Kensington is to take a train towards Hammersmith
only as far as Gloucester Road and change to a District/Piccadilly train
in the opposite direction.
