The Melbourne Metro 2 will not only be meeting the rising population's transit needs that are coming, but meeting other needs as well. The MM2 will become another train line that people will start to use as trains continue to become a more popular form of transportation. By helping keep people off roads and reducing car emissions, the MM2 will also provide a cheaper transit alternative for people looking to commute from the suburbs to the CBD. By furthering the public transportation infrastructure, Melbourne will be getting one step closer to becoming more interconnected as many of the worlds major cities currently are.
