I agree the Dubai Metro is a Mass Transit system, but you were talking about the monorail which has capacity to shuttle 40,000 a day along it's 3 mile stretch and is at less than 50% according to the operator figures not the overhead metro/train system.
It won't come to Manchester as it'd need private funding so would need a ROI making it too expensive and doesn't have the capacity for its purpose of transiting a football or concert crowd quickly.
This has been around for years, and not just to the stadium, and much like the proposed Picc-Vic line, it'd just be a show pony of something that's not needed but at least this won't get to even the draft planning stage.
Why do you think a monorail would be worth it, and how much would you pay to go on it?
