BYD-built monorail opens in Yinchuan

In mid-20th century, monorail was expected to be futuristic transportation.
But, as a result, it couldn't be a major transportation in urban areas, because monorail trains cannot go through conventional railways and maintaining cost is higher than ordinary railways.
But, monorail can be superior to monorails, when it comes to mountainous cities.
Since I don't think Yinchuan is the case, I wonder why the city adapted monorail systems.
