(under)Ground rules

Some ground rules. I’m using the standard Tube map as of July 2009 (so the DLR is included, as is the Overground, but not Croydon Tramlink or anything like that). A terminus is where you can’t go any further on one particular line. That sounds obvious but it’s important. Take Woodford, on the Central Line. A lot of trains end there, but you can continue on the same line, so it doesn’t count. Barking on the other hand counts even though you can go further out on the District Line; the Hammersmith and City and Overground end there. If it’s not a train line on the map it doesn’t count; thus no East London Line – which makes sense because one terminus would be Shoreditch which is no longer a tube station and will not reopen.
By these rules there are 36 termini:

1. Woolwich Arsenal (DLR) - Done!
2. Beckton (DLR) - Done!
3. Barking (Hammersmith and City, Overground) - Done!
