Hello,

Welcome to OSM.

I see you added a small path on the map.  You can see your path on the map already.  The only problem is that if a path is not connected to anything else, it will be pretty useless on the map.

Does this path connect the road somewhere?  I can help fixing this if you give some hints about where.

Anyway, the first correction to apply here should be to tag it as a private path, especially if it only used for railway maintenance and not aimed at any random person having a walk there.

Looking forward to your reply.
