Mapping former railroads in the USA
I came across the article at: https://www.atlasobscura.com/articles/mapping-ghostly-traces-abandoned-railroads-interactive-crowdsourced-atlas via one of the professional email lists I'm on.
This could be of interest to those recording routes of former rail lines?
The website at: https://www.google.com/maps/d/u/0/viewer?mid=1Q91IBeZLh916Q5auDaQ9-x25vh0&ll=39.59430285288446%2C-75.74770424999997&z=13 is primarily USA but when panning to Australia, I note a small number of former lines shown.
There is also the website at: http://www.abandonedrails.com/ (again, USA only?)
Mornington Peninsula, Victoria, Australia
