Alternative transport when trains are not running
From time to time, train lines or stations may be closed for maintenance, or trains may be stopped due to an incident or emergency.
When trains aren’t running, alternative transport will be available. This includes:
- Another rail service that will take you to or close to your destination. This may include detoured trains. For example, if there is an issue at Grafton station, the Onehunga West line might detour at Newmarket and take the South City line through the CRL tunnels and reconnect to the Onehunga West line at Maungawhau.
- Special bus replacement services that will connect between main transport hubs, such as Ōtāhuhu to Waitematā stations. Rail buses may take you to a nearby station to transfer to another train, so you can get to your destination faster, rather than running the entire length of the train line.
- Regular scheduled bus services that travel where you need to go.
There are signs at all train stations showing where you can catch replacement services and regular scheduled buses and where they travel to.
