Gleiswechseln

Gleiswechseln, also known as point work or switching, is the process of manipulating the position of railway points (or switches) to direct a train from one track to another. This operation is crucial for train routing, allowing trains to follow the most efficient path through a railway network. Points are mechanical devices consisting of a frog (the pivoting part) and two rails (the stock rails) that can be moved to connect a train to a different rail.

The primary goal of gleiswechseln is to ensure the safe and efficient movement of trains. It involves precise manipulation of the points to align the frog with the desired stock rail, which is then locked into position. This process requires careful coordination to avoid collisions and ensure that trains do not derail. Gleiswechseln is typically performed by railway signalmen or automated systems, depending on the level of automation in the railway network.

There are two main types of points: fixed points and movable points. Fixed points are permanently set in a specific direction and are used for simple track layouts. Movable points, on the other hand, can be adjusted manually or automatically to change the direction of the track. Movable points are further categorized into various types, such as frog points, disc points, and crossovers, each with different mechanisms and applications.

Gleiswechseln is a fundamental aspect of railway operations, enabling the complex web of tracks and signals that make up modern railway networks. It is essential for maintaining the safety and efficiency of railway systems, allowing trains to navigate through diverse and often congested railway landscapes.
