Johnsonville Line to take longer trains. Double-tracking the Kapiti Line from Mackays Crossing through Paraparaumu to just south of Waikanae, to increase capacity. (The double track stops short of Waikanae Station to avoid the cost of building second bridges over State Highway 1 and the Waikanae River.) Electrifying the Kapiti Line from Paraparaumu to Waikanae. Adding additional stabling storage at Paekakariki and Waikanae for the Matangi and Ganz Mavag units. Installing a third, bi-directional, line into between Wellington Station and the Kapiti/Hutt Valley line junction to ease congestion at peak times.
