Excellent! Is there a named, populated place nearby, or within a few kilometers? KM-290th will not show on the map at right unless it is a location recognized by GeoNames. Thanks!
KM-290th shows up on Google maps. That little village you see in the background is part of it, but there is no station building only a platform for passengers. I added it to GeoNames per the instructions that pop up when you put in a place that isn't recognized. Hopefully I did it right and it will be in GeoNames in a day or so.
