Time to update my signature.

Well done, that is some luck that I only wish I could have had on my 5th attempt... I reckon such a time is possible on my route, due to the absurd wait for the Hammersmith train.
You don't really need evicende, as such, for these alternative challenges as they're not official or anything.
Well done!
PS. You do need to do both Bank and Monument, as they are two separate stations that just happen to be connected by a walkway. You also have to do both the Hammersmith and Bakerloo/D&C Paddingtons, and both the Bakerloo/D&C and Hammersmith Edgware Roads.
