Glenroy ‘Big Dig’ well underway
06 Apr 2021
A nine-day construction blitz will kick off tonight, with crews excavating soil and rock along the Craigieburn rail line as part of work to remove the dangerous and congested level crossing at Glenroy Road and build a new Glenroy Station.
Around 19,000 vehicles pass through the Glenroy Road level crossing each day, with the boom gates down for up to 43 per cent of the morning peak.
Since March this year, the construction team has been working to remove around 80,000 cubic metres of rock and soil which is equal to about 30 Olympic-sized swimming pools.
By the end of this nine-day excavation marathon, the team will have removed 10,000 cubic metres – all of which is destined for a recycling facility. Once trains return to the tracks, crews will start excavation work underneath Glenroy Road.
Crews are expected to hit basalt rock – as the rail corridor is built on the Western Victorian Volcanic Plain, which is the third largest rock formation of its type in the world.
Digging through basalt rock creates more noise, dust and vibration compared with excavating other materials and can take longer to excavate than concrete. The project team will work closely with the community to mitigate any noise impacts as construction progresses.
Buses will replace trains on sections of the Craigieburn line from 8.15 pm Tuesday 6 April to first service on Friday 16 April so construction works can take place in the rail corridor.
Crews will also use this time to upgrade sleepers and other critical rail infrastructure along sections of the Craigieburn line.
While construction takes place in Glenroy, regional crews will also take the opportunity to complete work on the next stage of the Shepparton Line Upgrade and carry out bridge repairs, track maintenance, mud hole removal, culvert works, signal upgrades and repairs to some platforms.
Shepparton line trains will be replaced by coaches from first service on Wednesday, 7 April to first service on Sunday 18 April.
For regional passengers on the Seymour line, coaches will replace trains for the entire journey from 9.30 pm Tuesday 6 April to first service on Friday 16 April.
