From: LJ Holden
Dear KiwiRail,
In 2023 I requested an updated spreadsheet of data held on locomotive Mean Distance Between Failures (MDBF). The data series KiwiRail kindly provided covered all locomotive classes up to December 2022.
Under the Official Information Act 1982, I request the same data series from January 2023 to the most recently available figures (i.e. the last two years of data).
Yours faithfully,
LJ Holden
