Corridor
Corridors located within starships and space stations have typically served as pathways or passageways to various stations or quarters, and as lengthy hallways through which one might access various rooms.
Star Fleet
In order to maximize the use of space aboard Star Fleet vessels, the corridor system was designed to provide more than simply access from room to room. Several safety and survival features were built into the walls and ceilings, as were running lights to indicate whenever the starship was operating under alert status.
Corridors on board Star Fleet vessels were usually of two types: radial (those which run outward, pointing toward the outer hull) and concentric (those which lie in rings, interconnecting the radial corridors). The angled surfaces of each concealed different support structures.
Radial corridors were angled on either side. Their walls concealed a variety of supply lines and conduction systems, data networks, and power trunks. These systems were accessible by the removal of the snap-locked panels which cover them, and all were marked. The ship's concentric corridors housed personnel support systems. In each corridor segment, an emergency survival compartment existed which provides atmosphere, food and communications for one crew member; this provision was to be used should sudden decompression of the ship interior occur due to hull damage of life support failure.
On board starships in service since the twenty-fourth century, force fields could be erected in corridors to confine intruders.
Romulan
Interiors on board starships of the Romulan Star Empire are spartan and functional. Thus corridors on board Romulan vessels are wide, allowing quick and unrestricted access throughout the ship. Computer panels were provided throughout ship corridors, mounted against both sides of the wall, allowing easy access to ship systems.
Cardassian
Corridors on board starships and space stations of the Cardassian Union reflect the Cardassian preference of balance, angles, and hard metallic surfaces and dark colors. Cardassians believe in honesty in design and wish to see the columns and beams that make up a structure rather than disguising them with cosmetic treatment.
