Train users on the Craigieburn and Upfield lines are being warned to prepare for disruptions next week.
From Sunday, October 1 to Wednesday, October 4, Craigieburn trains will run direct to and from Flinders Street station rather than via the city loop, from 9pm until last service each night.
This will again be the case for both Craigieburn and Upfield trains from Friday, October 6 to Sunday, October 8.
On the Upfield line, buses replace trains between North Melbourne and Upfield stations from 8.35pm until the last service each night, from October 1 to October 4.
On the Craigieburn line, buses will replace trains between Broadmeadows and Craigieburn stations from 11.30pm until the last service each night from October 6 to October 8.
In other works, 55 car parking spaces at Craigieburn Station also remain closed until further notice, with additional parking available in the Hume Highway car park.
