Magnetic levitation operates differently from conventional rail technology in that it doesn't use wheels, bearings or axles. Instead, the magnetic field induced on either side of the vehicle helps to levitate and propel the train. As a result, there is no rolling friction, minimal maintenance costs, and little weather-related disruptions.
While the technology may be state-of-the-art, Shanghai Maglev faces other challenges since its inauguration in 2004. The most common criticism it has received is its short length, specifically that the line terminates in Longyang Road, which is around 8 km and 5 Metro stops away from Lujiazui financial district, and even further from notable sites in the city center, such as People's Square. The need to transfer for further 20-30 min journey adds to the inconvenience. Furthermore, riding the Maglev is relatively expensive. Single-ride economy seat starts at 40 RMB with proof of airline ticket purchase, while a typical moderate-length Metro ride costs 4 or 5 RMB.
There has been long-term plans to extend the Maglev into the city center, and continuing westward to Hongqiao Airport. Shanghai is growing at tremendous pace. Its Metro only began operating in 1995, but the ridership has already surpassed that of New York City Subway to claim world's 4th spot. As constructions for future lines and extensions occur by the minute, one can only hope that Maglev will be made more accessible soon. That the technology is remarkable is undisputed; only the operations stand in Maglev's way for it to transform transportation within and beyond China's largest city.
