Work on a groundbreaking rail loop connecting Melbourne’s spoked train system would start by about 2022, Transport Minister Jacinta Allan has told Neil Mitchell.

• VIDEO: See the plans

Ms Allan told Neil Mitchell the project would:

• Cost up to $50 billion
• Start about 2022
• Take about 30 years to complete

And she said sky rail would not be part of the design — we think.

Neil: Will there be sky rail?

Ms Allan: This is an underground rail loop.

Neil: So unequivocally no sky rail?

Ms Allan: I’d say it’d be difficult to put up sky rail in an underground rail loop. pic.twitter.com/S8YMOj5whM
