Hi all,

I wrote this proposal focused on power conversion in traction substations.
https://wiki.openstreetmap.org/wiki/Proposed_features/Traction_substations_extension

It is proposed to use a new key conversion=* to indicate which kind of
power conversion operates inside a substation.
As explained in rationale, no voltage=* nor frequency=* can be used as
reliable information to deduce it at the substation scale.
conversion=no explicitly means no power=converter device will be found in
the substation perimeter (for instance, high speed lines modern 25kV AC
traction systems)

This is an occasion to improve Paris railway substations mapping which
expose a few different situations
63 kV AC => 1500 V DC
63 kV AC => 25 kV AC
225 kV AC => 25 kV AC

Feel free to add opinions and concerns in Talk page

All the best

Fran├žois
