This may be a loong update for the s/b D but the Extension to Coney Island will soon be completed... Not as in 1, 2, 3 though... lol...
At First Stillwell was like this

But Now here's an update!

It's being worked on, but be advised there will be 2 versions: One with Actual Signals that will trip you if you fail to stop at the red signal: This is for OpenBVE
There will be a BVE2 Version that will have the wee ol' signals that is usually used in all the routes.
In addition, expect a detailed Coney Island Yard! This is also currenty being worked on!
