Line B = Trainz Mainline - congratulations Ben. A $20 credit will be emailed to your Planet Auran email address on Monday.
So c'mon folks, just the one Line remaining in this Zone with the massive clue: Rail Gone. It should be easy to unravel that clue.
To make it even easier, here was a very close guess from Steven Weekley on Facebook: C might be Trainz 2007 which was mainly 2006 with bonus content for certain regions. It would fit with the pattern of the timeline of being released around the same time Classics was.
While we are waiting for the next answer, there are no prizes for guessing the name of the Zone, but just for fun, any ideas of what the 3 Zone names might be?
No idea on Line C if it's not the Trainz Driver Branch. But that zone must be the PC Zone or something, although the TS12 branch is not in it (makes sense for the TS12 Branch to be closest to the YOU ARE HERE).
It appears the map discovery train has stalled on Branchline C. To clear the track and allow normal service to resume, I will post the results of the Zone 1 revelations and start the next challenge.
For those still playing, the clue "Rail Gone" is an anagram for "Regional" and the stops comprise various versions released for retail by publishers in specific markets around the world.
