This mod adds two additional technologies to the game so that when researched they allow the player to build passages at longer distances to reach nearby domes that are out of reach.

Additionally you have the option of choosing the Transport Tycoon Commander Profile to start with the "Faster Moving Walkways" tech right off the bat and an additional rockets. Passenger rockets can also carry 3 extra colonists.

There is also an additional Game Rule called "Sensible Passage Use" that removes the penalty imposed on colonists if accessing their workplace or a service in a dome other than their home dome.

ENGINEERING: Faster Moving Walkways making passage construction twice as long
BREAKTHROUGH: Hover Walkways making passage construction five times as long

FASTER MOVING WALKWAYS
With new advancements in motorized robotics, engineers have doubled the speed of the moving walkway platforms inside passages which in turn allows the construction of the passages to be double the length.

HOVER WALKWAYS
In a joint effort between the physics and engineering research departments, workers have devised a new way of public travel by using magnetism and "air under your feet" which allows the traveller to safely move through passages at incredible speeds, essentially making the motorized walkways much longer.
