The Changsha Maglev Express will be China's first medium speed urban maglev system. In late December 2015 it began vehicle testing along the route in preparation for opening later in 2016. Maglev technology eliminates most contact with the rail, dramatically reducing wear and tear and lowering long term operating costs. Most of the noise generated by the maglev is the electrical pickup shoe scraping along the bus bar. I wonder if they can find a way to reduce that noise.
