KiwiRail improves maintenance procedures following TAIC report

KiwiRail has changed its procedures at its Tranz Metro maintenance depot following an investigation into the Kaiwharawhara derailment on 20 May, 2013.

The derailment was found to have happened when the spring park brake on the last vehicle of the Ganz Mavag came loose as staff had not fitted split pins to the bolts that held it onto the bogie, General Manager Metro David Shepherd says.

“We moved quickly to implement the changes that the Transport Accident Investigation Commission (TAIC) recommended to prevent this sort of incident from occurring again.” 

Mr Shepherd says that the changes included improving the communication between staff so that the status and progress for any job is clear, especially during a shift change.

“After the derailment we immediately reviewed and changed the shift handover instructions to ensure that there is more detail on all stages of the maintenance work being undertaken and that any outstanding tasks for a particular job are clearly indicated.  

“Sign-off sheets are required to be completed and a secondary check was introduced for all work that is safety critical.

“By improving the communication within the team, and introducing the check system, we are in better position to help catch any errors that may occur during maintenance work.”

Mr Shepherd says that the team responsible for repairing and maintaining the Tranz Metro fleet at the Wellington depot are trade qualified and have many years’ experience between them. 

“Tranz Metro has an excellent record in maintenance safety, and serious incidents on the network due to mechanical depot failures are very rare.

“There are about 12 million passenger journeys on Tranz Metro each year and the safety of passengers and staff is our top priority.”
