As of version 1.0, the Rail package is available for Internet anonymous FTP from host phoibos.cs.kun.nl (131.174.81.1) in the directory pub/Rail. There is both a compressed and an uncompressed tar file, named rail.1.0.tar and rail.1.0.tar.Z, respectively. If you cannot use FTP, mail copies can be requested from the author of the package.
Please report any bugs or complaints to the author of the Rail package, L.W.J. Rooijakkers <lwj@cs.kun.nl>. Requests for features might be honored if I have the time (no chance :-)) or need the feature myself. Have fun!
