A free app for Android, by Colin Tucker.

The WHR Cae Pawb Signalling Simulation app is an Android app for the simulation of the WHR ‘Cae Pawb’ crossing, which is a diamond (or flat) crossing between the Welsh Highland Railway and the mainline (Network Rail). It allows you to control the signals and the train.

The app can be downloaded onto your Android device and used for free. It is also available for iOS devices.

It is intended for use with the WHR ‘Cae Pawb’ crossing and the signals, as well as the associated train and the railway line. It allows you to turn the signals on and off, as well as to change the speed of the train. It can be used for free.
