I was working on the Atlantic Branch at one point, from Atlantic Terminal to Jamaica.
http://forums.bvestation.com/index.php?topic=244.0Unfortunately I did not deliver, as I planned to grab photos of as many buildings along the line, as well as some in the distance to make it feel more realistic, much like TS2014 have at least 4-5 blocks of buildings surrounding the tracks. I didn't want to reuse any of the original NYCT objects. Regardless, it was too much work for me as a single person to do, and much more now with my real life work schedules. I've also lost a few textures since I made the route.
The luxury we have with NYCT routes was that the skeletons made by Joe were all accurate and based on actual track data. Something we lack with the LIRR and MNRR. My skeleton of the Atlantic Branch was more or less a guesstimate from Google Maps. So if anybody is interested, I can provide what I have of the route, but I do think it might be better to start from scratch. I'd have to check my computers to see if I still have it.
