A revised Brisbane Metro plan promises to halve travel times, reduce costs by a third and transport more commuters in an hour than the Gold Coast Light Rail service can do in a single day.

Lord Mayor Graham Quirk unveiled the plan on Saturday, saying the Brisbane City Council would not sit on its hands while the city's bus network was stretched thinner and thinner.

Cr Quirk said the council would also find an alternative to the Go Print site, with problems encountered in trying to secure the site as a maintenance and stabling depot making it "just too hard" and "unaffordable".

The site will be left for the Palaszczuk government to use in its Cross River Rail plans, with an alternative being sought "in the outer suburbs" and several sites under consideration, according to a spokesman from the Lord Mayor's office.
