Starwinder: The Ultimate Space Race(1996)

In Starwinder: The Ultimate Space Race, you assume the role of Conner Rhodes, the first representative of Earth sent to compete in a galaxy-wide race. This isn't an ordinary race, however -- an unknown alien race built magnificent rails/tracks throughout the confines of space. Spanning thousands of miles in length, rails act in such a way that when pilots navigate toward one, it increases the speed of the ship.
