Catch points

A catch point is a device installed at a railway signal. It ensures that a red signal is never passed and thus protects the line ahead at all costs by derailing the train if it attempts to pass the red signal. These may be also used in order to "catch" runaway wagons that may have decoupled in an uphill segment of line which may collide with following trains.
