The new AI Docking Rails are confusing me at the moment. How do you use the Pickup Rail, Shoot Off Rail, and Pickup Module? Also their textures are broken. XD
They have placeholders, but for the record they're supposed to be invisible anyway.
The Shoot Off Rail is intended to accelerate ships to high speed and then undock them... Currently, it does this, but the ships stop when they undock, a bug which has already been reported.
The Pick Up Rail and Pick Up Area don't seem to be functional at all, at the moment. The way I'd imagine it working, though, ships would fly into the Pick Up Area and would be automatically docked to the Pick Up Rail, from which they could appear to fly into your hangar bay and onto your system of normal rails. (In reality, though, they would simply be travelling along invisible Pick Up Rails.)
