What work is involved in the continuing rail maintenance

L Connolly made this Official Information request to Auckland Transport

The request was successful.

From: L Connolly

Dear Auckland Transport,
Over the 2020 - 2021 period there has been a large amount of urgent track maintenance on all train lines, with long shutdown periods and more work to come. What work is actually required? Full replacement of the sleepers? Steel of the tracks warping requiring new steel? Have the causes of these issues been identified? I know some of it has been preparing for the rail loop and I'm not interested in the detail around that as that's very transparent. We're all very curious about what the issue is and how long this could potentially take.

Yours faithfully,
L Connolly
