The Auckland Electrification Project (AEP) and Develop Auckland Rail Transport (DART) project will require complete replacement of the majority of the existing signalling system. By necessity, construction of the projects, including this new signalling system, will be carried out within a live, mixed traffic, railway environment.

All construction and installation work must therefore be carried out with minimal impact on train operations and disruption to the travelling public.

The interfaces and complexities of construction, installation, changeover and commissioning of a completely new signalling system within this live, working, railway environment will demand careful planning and implementation of:

• Track possessions to facilitate safe and maximised duration track access windows for construction activities.
• Minimised disruption to existing signalling and interlocking.

This paper summarises the signalling work to be undertaken as part of the AEP and DART Project and explains steps being taken to minimise disruption to the existing signalling during this work.
