enkelsporlinjer

Enkelspårlinjer, often translated as single-track lines, are railway lines where trains can only travel in one direction at a time. This is in contrast to double-track lines which have two parallel tracks allowing for simultaneous two-way traffic. The implementation of single-track lines is common in situations where traffic volume is low, or in areas where the cost of constructing a second track is prohibitive due to terrain or existing infrastructure.

Signaling systems are crucial for the safe operation of enkelspårlinjer. These systems, such as the absolute block system or token systems, ensure that only one train occupies a given section of track at any time. This prevents collisions, which are a significant risk on single-track routes. The capacity of a single-track line is inherently lower than that of a double-track line, as all movements must be coordinated and scheduled sequentially.

Despite their limitations, enkelspårlinjer remain an economically viable solution for many branch lines, rural routes, and low-density corridors. Investments in modern signaling technology, such as centralized traffic control (CTC) and improved communication systems, have enhanced the efficiency and safety of single-track operations. In some cases, passing loops or sidings are strategically placed along the line to allow trains to overtake each other or to wait for opposing traffic. These loops are essential for managing traffic flow on single-track routes.
