Halcyon Spaceport · Orbital Line 1
Boarding
Linear motors launch the train from rest to 149 km/h in about six seconds, ramping the push in and out so the fore/aft g never jumps, and the track pitches up into the climb while the motors still run, so the ride reaches 166 m on launch energy alone. Above the clouds, parabolic hills float riders at just under zero g. The track banks along the riders' heartline so sideways g goes to zero, roll rate is capped, and two trim brakes shed speed before the re-entry spiral and the city run.

Halcyon Spaceport · Orbital Line 1
Blast off from a garden city straight up the launch tower, punch through the clouds into the black, float over zero-g hills past an asteroid belt and a ring habitat, then spiral back down round the city's great spire and glide home through a forest under glass.
