Rain causes collision
Heavy rain and slips caused two trains to collide, and blocked part of State Highway 1 near Plimmerton last Thursday.
The trains, one carrying 40 passengers and the other 14 passengers and three KiwiRail staff, collided just after 3pm near Taupo Swamp.
One, heading north to Paraparaumu, struck a slip, derailed and was driven into the path of an oncoming south-bound locomotive.
Passengers said they feared they were going to die and spoke of showering glass on impact.
The drivers jumped from the cabs before the collision.
Wellington Free Ambulance said four people were taken to Wellington Hospital, two with spinal injuries, but three were released that evening.
The trains were cleared from the site overnight but commuters were forced to take buses on Friday.
Elsewhere on the rail network in this area, tracks subsided near Muri station in Pukerua Bay, with a 15-metre slip causing the earth to fall away from under the tracks.
On SH1, a slip near Whenua Tapu cemetery blocked a southbound lane for a time, but was cleared quickly.
Flooding closed Paekakariki Hill and Grays roads, and there were several slips in Pukerua Bay.
One hit a house in Te Ara Rd.
