Concerns about Wellington Railway Station were raised with KiwiRail years before a near-miss between two passenger trains sparked an investigation.
In November last year, a passenger train to Lower Hutt failed to stop at a red signal and headed towards a train coming from Waikanae.
Both train drivers realised what was happening and stopped the trains 30m apart.
Although there was no collision and no one was injured, it caused considerable disruption to services.
