Trains in Melbourne\u2019s Metro Tunnel will have to run slower near the new Parkville station, a leaked government report shows, under a plan to limit interference with sensitive cancer and medical scanning equipment.<\/p>\n\n\n\n

Flaws in the $14 billion project were exposed after a report to the state government\u2019s Infrastructure Development Committee was leaked to The Age<\/em>, revealing construction delays,<\/a> potential compensation claims and plans to dump elements of the mega-project to cut ballooning costs.<\/p>\n\n\n

But along with these issues, which the government argues are part of any infrastructure project of this scale, unresolved problems remain with cancer treatment equipment at the Peter MacCallum Cancer Centre in Parkville, and with sensitive microscopes at RMIT in the CBD.<\/p>\n\n\n\n

The new rail tunnel runs beneath Parkville\u2019s $1.2 billion Victorian Comprehensive Cancer Centre, which opened in 2016, two years before the tunnel started construction. The Peter Mac is located within the cancer centre.<\/p>\n\n\n\n

Trains running through the Metro Tunnel cause electromagnetic interference with medical equipment, an issue that planners began warning politicians in 2015 would need to be managed particularly with an eye to sensitive magnetic resonance imaging machines.<\/p>\n\n\n\n

MRI machines use magnetic fields and radio waves to take detailed pictures of patients.<\/p>\n\n\n

At one research centre in the precinct, the Peter Doherty Institute, the train tunnel runs just 20 metres from an ultra-sensitive microscope in the institute\u2019s basement, and has caused major issues.<\/p>\n\n\n\n

The leaked report makes clear that patients have not been affected because 11 MRI machines in the Parkville hospital precinct have been moved to upper levels of the Royal Melbourne Hospital, the Royal Women\u2019s Hospital, or to a cancer centre run by Peter Mac at its old East Melbourne site.<\/p>\n\n\n\n

The report puts costs to the taxpayer so far from the mitigation efforts at $181 million.<\/p>\n\n\n\n

During testing in June, machines at Peter Mac failed to meet reliability standards when trains ran through the tunnel under the hospital, the document says.<\/p>\n\n\n\n

The new rail line is expected to open to the public next year, with peak-hour trains running every three minutes beneath the hospital precinct. The leaked government report proposes a range of strategies to limit the trains\u2019 impact on hospital medical instruments.<\/p>\n\n\n\n

The report says that \u201cbased on advice from international experts and modelling of electromagnetic interference levels\u201d, mitigation strategies will include an amperage limit \u201cin the electrical section [of the rail tunnel] through Parkville, restricting High-Capacity Metro Trains\u2019 acceleration and deceleration performance\u201d.<\/p>\n\n\n\n

The fleet of 70 specially built High-Capacity Metro Trains to run through the tunnel cost Victorians $2.3 billion (there were originally 65 trains but five more were bought to run on the stalled airport rail line).<\/p>\n\n\n\n

The documents reveal that if more measures to deal with electromagnetic interference are not put in place, the trains could create further headaches when they are eventually upgraded from seven carriages to 10 as planned.<\/p>\n\n\n\n

\u201cThis is not anticipated for at least 15 years,\u201d the report says. <\/p>\n\n\n\n

Current strategies also do not account for the possibility of a second Metro Tunnel connecting to Parkville, and any increase in demand for power from the nearby tram network.<\/p>\n\n\n\n

The leaked report also shows that three transmission electron microscopes at RMIT\u2019s City Campus remain unreliable despite upgrades to shield them.<\/p>\n\n\n\n

The university and the project are in discussions about a $12 million commercial settlement, and RMIT is investigating a new facility where it could relocate sensitive equipment, notes on the status report say.<\/p>\n\n\n\n
