Comment from Chee Aun
In the change, some of the nodes have lost its `ref` information; especially the station codes like NS15 (for Yio Chu Kang MRT station).

Why was Dhoby Ghaut split into 2 different station nodes? Dhoby Ghaut is a 3 line interchange.

Hi Chee Aun,
I did preserve the ref-tag at the railway=station node. It won't be at the public_transport=stop_position node though. E.g. for Yio Chu Kang MRT station you will find it still intact here: https://www.openstreetmap.org/node/206529415
Let me know if you find a station where I accidentially removed it. I couldn't find any while reviewing today. -

Hi JaLooNz,
I hadn't finished reviewing the CCL line that's why it's station at Dhoby Ghaut was missing. Added this just today and you can see it part of the interchange relation stop_area_group here: https://www.openstreetmap.org/relation/7695989 -

Hi Claudius Henrichs,
The one intact (your link) was edited 1 year ago https://www.openstreetmap.org/node/206529415
The one modified by you (edited 3 months ago) https://www.openstreetmap.org/node/5200167957From 9 tags, it became 3 tags.

Hi Chee Aun,
There's a difference between the public_transport=stop_position and the railway=station nodes. In a complete mapping for a subway station both exist and describe different features. The stop position is the location on one of the multiple tracks that a train in a certain direction stops. This is very useful information as when you use trains on the same line but in opposite directions you need to go to different stop positions in the station. As you see for a normal subway line station with two tracks for each direction you would already have two stop position nodes. Sometimes these stop positions have ref-tags as well, e.g. track 1 and track 2, but they differ from the station ref.Additionally you would have either a node or an area for the building outline of the station. This is the OSM object that bears the station reference, e.g. ref=NS15 in case of Yio Chu Kang station.
These three nodes are combined using a public_transport=stop_area which you can find here: https://www.openstreetmap.org/relation/7695977
So in fact 9 tags became 15 if you combine all the node and relation information. And as you can see the station reference is still left intact in the station node: https://www.openstreetmap.org/node/206529415
btw. Maybe you can clear up if the amenity=bakery tag should remain on the station node. It looks like a tagging error. -
