The source code is hosted on SourceForge, so please download it from there. There are instructions on the FreeTrain project page on how to fetch the source code repository. Also, in the case you are just browsing the code, you can use the browse SVN feature. The build should succeed by just opening the sln file. There are at the time of writing (2003-01-18) no reports that the source fails to build. Let’s work together to create an even better FreeTrain!
