I did check the Auran Trainz website yesterday, but it was down. I should've known that Trainz sp3 was finally released (after a week long delay), and all the train 'nutters were overwhelming their servers downloading it!
"Trainz Service Pack 3 has arrived and is now ready for boarding. This service (pack) will take you to new heights, at greater speeds and allow you to experience Trainz in a whole new way with new content, SCENARIOS and layouts."
Uninformed train 'nutters please go here.
