[OSM-talk] stop deleting abandoned railroads

[John Eldredge]

Not precisely flat, but with very shallow grades, by definition. Regular 
railroad engines (as opposed to cog railway engines) can't climb steep 
slopes. So, if you are looking for a route without steep grades, a former 
railway is a natural choice.
