A points fault outside Wellington Railway Station has been fixed but commuters are being warned there will be congestion following delays and cancellations.
Hundreds of commuters were stuck at the central station earlier this evening during the peak hour commute.
Passengers should listen closely to announcements as there would be frequent platform changes into the evening, Transdev spokeswoman Emily Liddell said.
Kapiti, Hutt Valley and Melling Line services in and out of Wellington were all affected.
