Our regular maintenance activities include:
We use specialist machines including:
When track reaches the end of its life cycle, we replace the rail, sleepers and ballast. Sometimes the drainage system needs to be cleared and the formation replaced. On the Auckland metro network we are carrying out a major project to improve the resilience of underlying track infrastructure.
In certain situations we slow the speed of trains over a section of track - a temporary speed restriction – to ensure they can travel safely. We might do this when the rail gets very hot and risks buckling, while we are awaiting a permanent track repair, or after we’ve laid new track to give it time to ‘bed in’.
