This is about an Android railroad mapping app, "Rail Guide".
I sometimes struggle reconciling historic railroad location references with modern day map/land features. So I was quite pleased to learn about Rail Guide. A screenshot is attached, showing Monson area.
Users can select various overlays, choosing only active railroads, or only abandoned railroads, or a combination. There are 'historic' railroad names available, as well as 'modern' railroad names.
Free, if you want to put up with ads, or $10 /year to get rid of ads. Its not perfect -- if I look
hard I can find abandoned railroads not shown -- but its better than any other tool I have seen. Yes, the WW&F -- both historic and modern -- is on the map.
Available in the Play Store, some more info here:
