Signalling
The line is controlled by Preston Power Signal Box (PSB) from where it leaves the West Coast Main Line at Farington Curve Jn by Track Circuit Block signalling regulations until Midge Hall signal box. From here until Rufford signal box, the trains are signalled by Electric Token Block regulations, and from Rufford to Ormskirk the train is signalled by One Train Working with Train Staff regulations. If at any time there is a problem with either the token machine or track circuits showing occupied, then pilotman working must be implemented.
