a mechanical device activated by the weight or movement of a train's wheels, typically used to trigger signals or track switches
A treadle is a device often used in railway signaling that is activated by pressure, typically from the weight of a train passing over it. When a train's wheels press down on the treadle, it triggers a mechanical signal or system, such as changing the position of a track switch or activating a warning signal. Treadles are commonly found in places where automatic track changes or alerts are needed, helping to manage train movements and improve safety without requiring manual intervention. They are usually placed in strategic locations along the track to ensure proper functioning of signaling equipment.
- Treadles are strategically placed along the railway tracks to detect the presence of trains and facilitate safe operations.
