Network Rail has identified a series of interventions to increase capacity on the South West main line between Woking and London Waterloo as passenger demand recovers in the longer-term. The findings are contained in its South West main line strategic study.
Prior to the Covid-19 pandemic, the Woking to Waterloo section was full in the high peak period, leading to relatively poor performance. Headways are presently around two minutes, with the flat junction at Woking and the need for empty coaching stock movements from Waterloo to share tracks with main line trains going into the station also presenting constraints.
