signalväxels

Signalväxels is a Swedish term referring to a type of railway signaling system. It translates directly to "signal interlock" or "signal interlocking." This system is a safety mechanism designed to prevent conflicting train movements on a railway network. The core principle of signalväxels is that it ensures that signals display the correct aspects (colors and positions) based on the status of the track sections and points (switches). Essentially, the interlocking prevents signals from showing a clear aspect if the route ahead is not set correctly and secured. This includes ensuring that points are in the correct position and locked before a signal can authorize a train to proceed. The system is crucial for maintaining the safe operation of railways by eliminating the possibility of human error leading to collisions or derailments. Modern signalväxels systems can be mechanical, electrical, or electronic, with electronic interlocking being the most prevalent today due to its flexibility and advanced capabilities. These systems are a fundamental component of railway infrastructure worldwide, ensuring the safety and efficiency of train traffic.
