The data in NaPTAN does not include the '/' actually, probably because
of the work being done to standardise stop naming across the UK in
NaPTAN. In particular to discourage stop naming of the form 'street/
cross street' and the use of some characters including /. In this case
the slash has gone but the cross street naming remains.

Yes there are entrances in NaPTAN. For example there are 8 entrances
given for Oxford Street Underground station. There are also platforms
information, but no indication about which platform they relate to.
Can I suggest we complete the import of bus stops import into OSM
first and then go back for another trawl through the data and get more
