[Tagging] Feature proposal - RFC - Railway/Power traction substations

[François Lacombe]

Hi

The traction power substation proposal has been updated regarding possible
values
conversion=(acac, acdc, no) was moved to conversion=(ac_ac, ac_dc, no)

This was a concern raised in private discussion.

Vote will begin shortly if no additional point comes in mind

All the best
