The Metropolitan Atlanta Rapid Transit Authority (MARTA) operates a subway system in the metro Atlanta area.
On the East-West Line, the line on the west side of Five Points Station (osm.org/go/ZQqqob6FH--) is drawn with a single line marked as railway=subway.
East of Five Points, the line is drawn as two parallel lines marked as railway=rail (see Kensington station for a fairly clean example: osm.org/go/ZSACaBv6o-).
The railway=station tag (osm.wiki/Tag:railway%3Dstation) seems to be intended for use as a point on a single line representing a railway.
Would it be more useful for me to merge the eastbound and westbound rails for MARTA or is it more useful having each direction drawn separately?
(I intend to change all of the MARTA lines to railway=subway but it would probably be easier to go through and make all of the changes at once...)
Thanks,

The railway=station tag can be applied to a single node or to an area. If you use it for a node, that node does not need to be a member of the way representing the rail; it just marks the spot where the station name and icon should be rendered.

Thanks, lyx. That means that I don't have to make the Kensington Station example a part of one of those two ways.
My bigger question/concern is: does it matter if a single MARTA route has two ways (one for each direction) or should I go through the process of drawing a single representative way for the East-West Line?
