West Dulwich has a low bridge over the South Circular (4.4m headroom) so isn't much higher than Shortlands - though the two lots of steps on my daily commute many years ago kept me fit!West Dulwich?
The most spectacular I can think of is Valle Aurelia in the NW suburbs of Rome, where the FS station is on a modern viaduct several floors above street level. No idea of the actual height difference.
