You must have a registered copy of Trainz and it must be version TRS2009 or later. The new files are now only available on the N3V (Auran)Download Station. They are no longer available from the original web site. There are over 1700 individual files that must be downloaded. We regret that this route is no longer supported on Trainz versions prior to TRS2009.. Any questions should be addressed to the DHR thread on the Trainz forum.
