vaihtimien

Vaihtimien refers to mechanical devices used to change the direction or path of something, most commonly in railway and tramway systems. These are also known as switches or points. A set of vaihtimien allows a train or tram to move from one track to another. The main components include the movable tongue rails, which are pivoted at one end and can be swung to connect with the corresponding stock rails, thereby creating a continuous path.

The operation of vaihtimien is typically controlled by a lever or an electrical system. In manual systems, an operator physically moves the lever to set the direction. In more modern installations, electromechanical or hydraulic actuators are used, often integrated into a signaling system. This allows for remote control and enhances safety by ensuring that vaihtimien are correctly aligned before a vehicle passes over them.

Vaihtimien are crucial for the efficient and safe operation of any rail network. They enable trains to diverge onto different lines, enter sidings for maintenance or storage, or switch between tracks in stations and yards. The design and maintenance of vaihtimien are critical to prevent derailments and ensure smooth transitions between tracks. Different types of vaihtimien exist, designed for various speeds, axle loads, and track configurations.
