DEVELOPING: It will take until Monday to get trains back on track in Melbourne’s northeast. A delicate operation is underway to crane a derailed carriage from Clifton Hill, and as Sara Jones reports, that is only the beginning of the massive repair mission. #7NEWS

The closure of two train lines is about to hit the evening peak for the second day running. Both Mernda and Hurstbridge lines are suspended indefinitely after a passenger carriage came off the tracks at Clifton Hill.

@SaraJones_7 The explanation for cause doesn’t seem very clear from what I have read. What actually caused train to derail?

@SaraJones_7 Australia is not a first world country.

@SaraJones_7 Ffs Should take non union workers 5 minutes

@SaraJones_7 Victoria is being destroyed, trains not running due to works on lines and now a derailment Northland shopping centre being avoided due to machete wielding gangs Ambulances ramped, hospitals full, public dying on trolleys in hallways Seriously what a disgrace
