Hi cmxn,

The general consensus in the community is that only railways with remaining remnants on the ground (such as a remaining grade as the bar minimum) should be mapped. Otherwise, these "abandoned" railways should not be mapped. However, this kind of work is perfect for OpenHistoricalMap at openhistoricalmap.org. There's some discussion on it here, if you're interested: https://community.openstreetmap.org/t/proposing-to-deprecate-railway-razed-and-railway-dismantled/109679/64

I will probably delete the railways that you have mapped in a week or so or whenever you have had time to move them over to OHM.

Thanks, BubbaJuice
