Rail Guide is an App with maps of railroads in the US, Canada, and Mexico, past and present. It's available as web page on your desktop as well as free apps for Apple and Android devices. Not only does the app feature current rail lines but also Historic streetcar and interurban lines for many areas. There is even an option to show the locations of former Roundhouses. From the main map choose the MAP button and select ATTRACTIONS to view the Roundhouse locations.
