Hi Eckhard,

I just realized that the ICE railway Mannheim-Stuttgart almost disappeared from OSM. Due to the renovation works somebody changed it to railway=construction (e.g. see https://www.openstreetmap.org/way/156403088)

Is it the right idea to mark railways as construction during renovation works like that? What do you think?

The renovation works on the old high speed lines in Germany take a couple of months each (e.g. April to October 2020 for Mannheim–Stuttgart). When you have a look at road mapping in OSM, you will notice that people put roads under construction which are closed for a couple of months. It happens that rarely with railways (for whatever reason) in OSM that we are not used to it.

In Germany, the rule of thumb for road mapping says that a closures of a road due to construction are mapped if the road is closed for a minimum time of six weeks to six months (different mappers have different thresholds). I myself am fine if people follow this threshold for railways as well and take care to reopen it when the constructions are over.

Best regards

Michael
