Someone told me that there are merely three oversize freight car types in

15" would be considered unusually low in the UK other than for
trams... most low platforms (not many left) are at least 2', and the
standard for high platforms is 915mm (above rail height) which is 3'.

Indeed, most new-build bus stops in the UK now have "platforms" of
probably about 6-8".
