TrapInterail

TrapInterail is a type of railway trap, a device used to prevent the unauthorized movement of trains along a railway line. It is designed to be activated by the presence of a train, typically through the use of a rail-mounted sensor or switch. Once activated, the trap prevents the train from proceeding further by lifting a barrier or engaging a locking mechanism. TrapInterails are commonly used in railway yards, maintenance depots, and other locations where trains need to be controlled or restricted.

The primary purpose of a TrapInterail is to ensure the safety and security of railway operations. By preventing unauthorized movement, it helps to prevent accidents, derailments, and other incidents that could occur if trains were to move without proper authorization. Additionally, TrapInterails can be used to control the flow of traffic, allowing for the efficient management of railway yards and depots.

TrapInterails are typically operated manually by railway staff, who activate the trap when a train is present and deactivate it once the train has cleared the area. In some cases, automatic systems may be used, which can activate and deactivate the trap based on the presence of a train. These systems often use sensors or switches to detect the train's position and operate the trap accordingly.

The design and operation of TrapInterails can vary depending on the specific requirements of the railway and the location where they are installed. However, they all share the common goal of preventing unauthorized train movement and ensuring the safe and efficient operation of railway systems.
