enkelspårsbanor

Enkelspårsbanor refer to railway lines that have only a single track for trains to run on. This is in contrast to double-track lines, which have two parallel tracks allowing trains to travel in opposite directions simultaneously. The implementation of single-track lines is often a consequence of economic considerations, as they are less expensive to build and maintain than double-track lines. They are common in areas with lower traffic density or on branch lines where the volume of train movements does not necessitate the capacity of a double-track system.

Operating trains on single-track lines requires careful scheduling and traffic management to ensure safety and efficiency. This typically involves the use of signaling systems and specific operational procedures to prevent collisions. One common method is the use of token systems, where a physical token grants a train the right to occupy a specific section of track. More modern approaches utilize centralized traffic control (CTC) or automatic block signaling (ABS) systems, which allow dispatchers to monitor and control train movements remotely. In some cases, passing loops or sidings are incorporated into single-track lines. These are short sections of double track that allow trains to pass each other or to wait for scheduled meets. The capacity of a single-track line is inherently limited by the need for these operational measures.
