Hows that working out? Have you had any problems with the rails getting wrecked?
I've had only problems with end station's wall and ferry's front landing gear, front thrusters and lights being wrecked when I disabled inertial dampeners.
Other than that, it works just great.
Or getting it onto the rails for that matter.
I built the ship close to the center of the rails. It was a little "above" the rails, so I've put a thruster on the top of the ferry to move it down until it touched the rails with its arms, and then I removed that thruster and built the bottom of the arms to keep it on the rails without flying away.
Sure, but it does the same job as Orb's asteroid ferry
My ferry includes also 8 medium cargo containers (or it could be 2 large and a few small) for the future cargo that could be mined on one of the asteroids and transported for processing to the other.
What did you use for the rails anyway?
What Izack said - pillars.
