Open Rails's source code is organised as a Visual Studio solution - see Compiling The Open Rails Project for free and commercial Visual Studio products.
One of the ways that the Free Software License (GPL) protects our rights is by requiring everyone who distributes software under the GPL to make the source available also. That way, everyone who uses the software can examine it and customize it if they wish.
The entire history of project development is archived in our public Git repository, so visitors are able to extract not just the current version but all the previous ones too back to version 1 in December 2009.
