Delays a train from exiting a tunnel to give the appearance of a long tunnel. Can also be used to control signals at a station for the train to stop making the train wait for a predetermined time before letting it continue. With this arrangement the sensor will automatically stop the train with the isolated track and the signal will remain red, when the train is at the station. After the predetermined time the signal will turn green, the relay will close and let the train continue.
Another use this module has is a two aspect signaling system with the onboard LED or lamp drivers.
With the addition of an express switch the tunnel stretcher or station signals may be overridden, forcing the signal green and letting an express or goods train pass on by without the delay.
