railroad line
Tracks connecting stations
A railroad line is a route or track along which trains travel, or the company that operates such a route.
The term refers both to the physical infrastructure—rails, ties, and roadbed—and to the transportation service itself: The railroad line runs through three states.
Multiple tracks serving the same route still constitute one line.
