Council transport strategy manager Kevin Wright said terms of reference had been prepared for "detailed studies to examine the system-wide costs and benefits of long-term solutions to remove conflict between traffic and trains at all 48 level crossings on the Auckland rail network".
Although KiwiRail was meanwhile exploring short-term solutions, improvements such as building bridges to "grade separate" road traffic from trains would need extra funding.
Some sites could cost anything from $20 million to $100 million to safeguard, and Auckland Transport would have to consult the Transport Agency - which allocates Government subsidies - in assessing projects against other priorities.
Although KiwiRail is responsible for the safety of level crossings, and is still investigating the near tragedy in Morningside, it says it is up to road controlling authorities such as Auckland Transport to make funding decisions about grade-separation projects.
The council committee has decided to support in principle a programme of grade-separating dangerous crossings "as soon as financially practical" in the 2014-15 fiscal year.
Councillor Cathy Casey said in proposing the resolution that three of what Auckland Transport deemed to be the region's eight most dangerous crossings - including Morningside's - were in her Albert-Eden-Roskill ward and she was "totally unimpressed" by the organisation's actions so far.
"The resolutions that have gone from the [Albert-Eden] board to Auckland Transport are legion - they have been totally ignored until someone almost died."
Council principal transport planner Darren Davis said that although level-crossing accidents were relatively rare, the consequences were often very bad and risks would increase when faster and quieter electric trains started running next year, more frequently than the existing diesels, albeit with twice the braking power.
The only two recent grade separations were those created by New Lynn's $150 million railway trench.
The only new separation project on the books was at Sarawia St, which is close enough to the critical Newmarket railway junction for Auckland Transport to have allocated $6.2 million for a detour road or a bridge over the tracks, on which it is consulting the local community over the best option.
