Manual control
The train control system provides the ability to activate certain level crossing alarms that were historically controlled by local signal boxes. With the closure of local signal boxes these locations can be controlled remotely from the train control centre in Wellington. Some level crossings do not require the ability to be activated remotely and rely on automatic activation by the approach of a train.
