The Barnham and Ford route has been development by the ROS development team for simple simulations to demonstrate the joining and splitting of services. The small simulated section of the West Coastway line between Brighton and Portsmouth includes four main junctions, including Barnham Junction where services diverge towards Bognor Regis, and Ford, Littlehampton and Arundel junctions with services heading towards either Three Bridges via the Arun Valley line, or Littlehampton in the south.
