Commuter trains on Auckland's rail network are back up and running after a breakdown forced three out of four lines to be shut down.

All services on the Southern, Eastern and Onehunga lines were temporarily suspended while the network was reset after an engine broke down in Otahuhu earlier this morning.

Auckland Transport spokesman Mark Hannan said trains were now running on the three affected lines.

Auckland Transport was aiming to have everything back to normal by 11am after people had been urged to use public transport to travel to Eden Park for today's memorial service.

The Western line was unaffected by this morning's disruption and was operating normally.

It's not yet known what's caused the agency to halt the trains.

Buses were brought in earlier to transfer passengers but people were warned to expect delays.

Auckland Transport tweeted a limited replacement bus service was operating between Otahuhu and Orakei and The Strand.

Another was operating between Onehunga and Penrose.
