Government promises $80m study into duplicating Upfield Line, delaying level crossing removal

In short:

The Carroll government will delay level crossing removals and begin preliminary work on duplicating the Upfield line if re-elected.

The line through Melbourne's northern suburbs still has a section of single-line track, limiting the amount of services.

The government has pledged to spend $80 million on a study into the cost of duplicating the rail line.
