Charing Cross, Waterloo East (where is London Waterloo? Is it a different station from London Waterloo East?) and London Bridge are all on the same line and London Victoria isn't far from it at all - so clearly a massive amount of rail use from southeast (Kent) into London - probably mostly daily commuters, don't you think?

Maidstone Barracks is the only one of the little-used stations I recognize, just because it's also in that southeast/Kent grouping of stations; I spent a lot of time going to Gravesend!
