BTS/MRT/ARL or any other underground/sky train station.

Hi,

I’m wondering about how should we map underground/skytrain station? Currently we have only “Railway Station” object.

Moreover, if that station has more than 1 exit across the area, how should we map it?

For example, MRT Suttisarn Station (สุทธิสาร) is mapped with “Railway Station” http://www.openstreetmap.org/?lat=13.788491&lon=100.57453&zoom=18&layers=M and it has 4 exits across the Suttisarn Junction.

Thank you,
Keng.

Here is an example of the Metro of Madrid in Spain, it’s done trough relationships.

you can define subway stops and subway entrances, also you can have diferent lines of the subway or skytrain (for example Sukhumvit Line and SiLom line). If you need a hand I can help you out doing that for Bangkok.
