WRRP: planning and construction of the third main track into Wellington Station

The paper will focus on the successful delivery of the third main track into Wellington Station. The concept for the revised railway was remarkably simple: a doubling of capacity for passenger operations during peak periods by adding a bi-directional main line. Complexity was introduced, however, through a lack of room in the rail corridor, the main lines running through a rail yard that provided the main terminus for freight operations, limited ability to ‘block the line’ for the upgrade works and a complete rebuild of the signalling and traction supply systems. Working in close partnership with the KiwiRail operators allowed the early establishment of an agreed schedule of access to the railway corridor, firm management of interface risks due to construction works occurring within close proximity of railway operations and a clear route for out-of-the-ordinary requests such as temporary rule changes. Cooperative programming workshops involving all contractors identified an optimised construction sequence that de-risked the heavily constrained programme and improved the chances for successful completion. Integrated planning sessions in advance of critical weekend blockades allowed for detailed planning around construction interfaces and allowed for busy shared worksites. Throughout, a ‘best-for-project’ attitude ensured constructability issues were either identified and mitigated in advance, or could be dealt with by established mechanisms quickly, to limit delays and avoid consequential impact upon restart of railway operations. Ultimately the project has been completed without lost-time injury, with timely handback of weekend possessions of the railway corridor and within the timeframe required by KiwiRail.
