Monorails are the unicorns of public transport. They sound great but are generaly failures and many systems have been removed after quite short operational lives.
The reason is pretty simple. If the monorail is at ground level then it's no cheaper and less efficient than a traditional train or tram system. If the monorail is elevated then, sure, it's cheap to build, but it's an unpleasant intrusion in the public realm, inconveinient for passengers and very expensive to maintain.
Off the top of my head, NY, Sydney and Liverpool have all had monorails or elevated railway systems that were removed because of their unpopularity with residents and low passenger numbers.
