Anyone who has used Southeastern services through Lewisham will have asked the question to themselves - why does St John's exist? Well, maybe not the people who actually use it, and that number is actually steadily growing every year. Apparently St John's (which was named after a church that was somehow built after it) is the product of a furious squabble between South Eastern Railway and the London Chatham and Dover Railway. LCDR had opened a station called Lewisham Road, on their now closed Greenwich Park branch, so SER struck back with St John's - and we're all here now to bask in their total, and utter victory. To the victor go the spoils, and the spoils in this case was St John's. The fact that there are theories as to why St John's exists says it all - we don't need theories for Lewisham or New Cross, their existence is self-evident, but St John's? No, there must be an ulterior motive behind St John's construction other than 'convenience'. This might surprise some people, but when it opened it had, brace yourself, three lengthy island platforms. Admittedly two of those platforms served one track, but still, three. Wow. Anyhow, our theory as to why St John's is so high on this list is that, though it's actually more used than quite a few of the stations included on our original shortlist, it suffers from the fact that more people know that St John's isn't well-used because of it's location between Lewisham and New Cross.
