Make sure to find a random spot far out into the ocean (fly there, drop a Drood, save location, make sure location agl and velocity are both ZERO). Then spawn the track in said location. If it's too shallow, or on land, it'll explode.

In the future, Droo's population has increased into a large, peaceful, beautiful society dedicated to science. The planet is a utopia. However, transportation is still required. The leading aerospace giant and technological behemoth, Jundroo, has built a massive experimental Maglev for the people. Due to its being in experimental phase, the SimpleMaglev is still not as fast as it could be, the interior is a bit...dry, and rides are bumpy. However, you and a few other Droods have taken up the task of operating and observing the SimpleMaglev, in the name of science and simply enjoying the pleasant ocean ride.

Press space to disconnect interstage (back when the maglev was on land, this was the only way to keep the track from sinking into the ground, so I kept it as a safety precaution). Pitch makes you move, pitch slider up for a long relaxing ride, or pitch down to go backwards. You can time warp, but I don' t suggest doing it while moving (it's untested). Don't worry about zooming in on the craft, when you press space it should automatically zoom onto the traincar. In the case that it doesn't, just zoom in. Feel free to take control of a Drood and watch the ocean pass by the window. Also feel free to strap rockets to the maglev, but it won't last long.

Track diameter: 4.6 km

Track circumference: 14.5 km

P.S., AG 1 is useless, just makes the little light up front blink.
Also P.S., if it gets stuck, explode one of the side wheels and it should come free (they phase through the track sometimes).
