It has been reported that our second FreeTrain release has a serious bug that prevents you from buying or selling trains, leaving you with only the tree starting ones. Due to the seriousness of this bug, this release has been removed from the download page. We are working hard on fixing the issue and will make a new release ASAP.
For all of you who downloaded the second release, it is advised that you get the first release instead in the meantime. The difference between the two is minimal feature-wise.
