I’ve always liked Whitechapel Station, where the District line emerges blinking into the daylight and curves round to head eastwards towards West Ham and Upminster, whilst below one could catch the old branch line of the Metropolitan down to New Cross, now revitalised by becoming part of the London Overground.   The station opened in 1902 and one used to be able to get the Whitechapel & Bow Railway all the way to Southend.   It had four platforms, now reduced to two, and it’s gradually losing its character as it is submerged by the changes required for Crossrail:-
