Auckland’s train commuters face significant disruption over the coming month, with the entire rail network set to close over the Easter long weekend and for three weekdays during the April school holidays. The closures are essential for final upgrade and testing work on the long-awaited City Rail Link (CRL), which is slated to open in the second half of this year.
Auckland Transport (AT) has confirmed the network-wide closures will take place from April 3-6 for Easter, and again from April 13-15 for intensive timetable testing. A further closure is scheduled for the ANZAC Day long weekend, from 2pm on Saturday, April 25, until the morning of Tuesday, April 28. Partial and full-line closures will also occur at other times during the school holidays.
To mitigate the impact on travellers, AT has organised more than 100 replacement bus services, including express options for passengers on the Western and Southern lines. This represents a nearly 60 per cent increase in capacity compared to the bus fleet used during similar closures in January.
Critical upgrades to modernise network
The April shutdowns will allow KiwiRail and AT to undertake a range of crucial upgrades necessary to integrate the CRL with the existing network. The work includes significant upgrades at Henderson station, the replacement of level crossings with three new station bridges, and widespread track renewals and replacements.
Crews will also work on the three new stations in Drury, south of the city, and carry out extensive infrastructure and signalling improvements. Modernised signalling is fundamental to the operation of the CRL, as it will allow for more trains to run more frequently and reliably across the city's 45 stations. These improvements are a core component of the wider City Rail Link project, which aims to double the capacity of the isthmus rail network.
Auckland Transport’s Director of Public Transport and Active Modes, Stacey van der Putten, says the work cannot be delayed without jeopardising the CRL's planned opening later this year. She acknowledged the timing is inconvenient but stressed the project was at a critical stage.
We know more people are turning to public transport as fuel prices rise. These works are on the critical path and delaying them now would result in delays completing City Rail Link work and ultimately opening the new services to Aucklanders.
Testing the new CRL timetable
A key part of the planned closures is the three-day testing period from April 13-15, which will simulate the conditions of the new, expanded network. When the CRL opens, it will introduce a completely new timetable with three new train lines – the East West, South City, and Onehunga West – and three new underground stations in the central city.
This complexity requires rigorous testing to ensure a smooth and reliable launch. Ms van der Putten says AT is following international best practice by planning a staged rollout, beginning with a transitional timetable before ramping up to higher frequency services.
“Our priority when opening City Rail Link is to provide reliable services,” she says. “We will open City Rail Link with a temporary transitional timetable to help customers and our staff get used to the changes. We will test both this temporary timetable and the higher frequency peak train services that we plan to ramp up to within about six months.”
The dry runs will allow train controllers, drivers, and station staff to practise managing a much busier and more complex network. The testing covers everything from train positioning and scheduling to the accuracy of real-time passenger information displayed on station screens, trains, and the Auckland Transport app. Coordinating services across 45 stations to a timetable measured in seconds is an immense logistical task.
Replacement buses to manage disruption
Recognising the inconvenience, AT has bolstered its rail replacement bus services. A full complement of over 100 buses will be available during all closures, with express services for the heavily used Southern and Western lines. Additional buses will also be on standby to be deployed where needed if scheduled services become full.
Many of the replacement buses will be fitted with GPS tracking, allowing passengers to monitor arrival times in the AT mobile app. Public transport users are encouraged to use the AT Journey Planner ahead of time to check the rail bus timetables and explore their options. Regularly scheduled local bus services, which run at least every 15 minutes on major routes from 7am to 7pm, remain another alternative for commuters.
The investment in replacement services mirrors efforts in other cities modernising their public transport infrastructure, such as in California, where the San Diego Metropolitan Transit System recently received significant funding to upgrade its trolley fleet.
During the closures, AT has issued a safety reminder that while passenger trains will not be running, work trains and other rail vehicles will still be using the tracks. All commuters and pedestrians are urged to remain vigilant at level crossings, stop, and check both ways for trains before crossing.
The full schedule of planned closures, including partial line shutdowns during the school holiday period, can be found on the Auckland Transport website. Ms van der Putten says the intensive work in April will help confirm what the transitional timetable will look like and how long it will be in place before the full benefits of the CRL are realised.
