Major Routes

Major Routes tie together the high population, technologically advanced worlds of the Highlands. They make it easy for vehicles without shunt capable Barnes-Gutierrez Engines to travel between star systems. Brakes, small RV size vehicles without shutting capability, are within the budget of many families. They allow even people of relatively modest means the ability to travel to foreign systems. Of course the hypertrains that travel the Major Routes also put interstellar travel within the budget of many Highlanders.
Travel along a Major Route is relatively safe. Vehicles enter at a portal gate, usually in orbit around the planetary solar primary. Once through the gate the auto navigation system of  most vehicles will lock onto one of the directional beacons toward the destination gate.
Major Routes typically have a redundant number of beacon stations to ensure clear navigation through subspace, avoiding plateau gravitational shear planes and other subspace hazards. Most beacons are simply unmanned stations locked on to the subspace plane with gravitational anchors. Others are manned, sometimes hypercable relay stations, Highland Ranger outposts or Department of Roads equipment warehouses.
If the distance between worlds is too great, more than several days distance, its likely that a waystation has been constructed along the Route. Waystations are the equivalent of the subspace truck stop. While hypertrains do not usually stop at them, all other vehicles typically make use of these convenient multi-purpose structures.
The typical waystation contains restaurants where travelers can get a good meal, rooms where they can spread out in more comfort than many brake or hyperlorry sleeper compartments, repair shops for those vehicles which break down, snack and grocery shops to pick up food to go, and even tourist shops to drop a little extra cash on bobble headed Saint icons and cunning hats. Needless to say there is almost always a chapel, sometime several belonging to different rites.
Of course travelers are not compelled to stop at any station or gate they pass in subspace. Still worlds on Major Routes are host to millions of visitors a year, most of whom are just passing through on their way down the Major Routes.
One of the dangers of subspace travel is subspace storms. Gravitational sensor can often detect such gravitational shear planes before they cut through Routes and Highways, but not always. The Department of Roads maintains a storm watch channel and smart travelers monitor, or have their vehicle monitor the DOR storm watch channel.
