Everything up there is dead. <3>Train and GE&P(6) are talking about some copyright issues, and <3>Train does not even have the tunnels. He made them, but he lost them, and GE&P(6) and BStyles have them. They say it would be some copyright issue stuff, so BStyles is currently making some new tunnels in collab with GE&P(6).
The open-cut stuff, GE&P(6) lost all of that stuff when he lost his NYCTA content. This was part of the and lines. I asked him about this stuff and he said it is coming back soon.
If you hit the Auran forums, you can see plenty new content, including some more realistic, less poly count EL tracks by BStyles.
