ARK were contracted to analyse the Northern Rail Priority Area 1 and record the associated signalling data from Signalling Plans and Control Tables. This data is fed into the VISION software package to model capacity and allow Capacity Planning. Priority Area 1 involved the analysis of approximately 1,300 signals, the data was successfully delivered to a very ambitious programme.

Our success in the delivery of Priority Area 1 led to us being chosen to supply services in the extraction of data for a further 38,000 signals and associated data. This resulted in ARK delivering signal data for the entire NR network covering England, Wales and Scotland.
