Trains are back in service in Auckland today after a two-week shutdown for work including the installation of new signals needed to handle Rugby World Cup crowds.
Passenger services are expected to resume on the western line, the Onehunga line and between Otahuhu and Britomart on the southern line.
Buses will keep replacing trains for another week south of Otahuhu and on the eastern line as work continues on five replacement bridges and lowering of tracks through the 800m Purewa Tunnel west of Glen Innes for the $1 billion rail-electrification project.
Limited freight trains will run only along the southern line, using one set of tracks through construction zones.
KiwiRail has spent the fortnight since Boxing Day resignalling the critical Quay Park rail junction in downtown Auckland for the "bi-directional" running of trains needed to clear Kingsland Station of 15,000 rugby fans in 75 minutes after Cup finals.
