Budget to pour billions into suburban rail

Billions of dollars will be set aside for suburban rail projects when Treasurer Scott Morrison hands down his second budget on Tuesday night.

The federal budget will include a multi-billion dollar suburban rail package, reports suggest.

The Turnbull government has already hinted at funding for the inland rail freight project linking Melbourne and Brisbane.

But the ABC and Sky News report billions will also be set aside for urban projects when Treasurer Scott Morrison hands down his second budget later on Tuesday.
