What is "h-bahn"

The H-Bahn ("Hängebahn", or "hanging railway") in Dortmund and Düsseldorf is a suspended, driverless passenger suspension railway system. The system was developed by Siemens, who call the project SIPEM (SIemens PEople Mover).

Two installations exist, one at the Dortmund university campus, the other at the Düsseldorf International Airport. While Siemens is no longer actively marketing the system, and will no longer carry out turnkey projects, new installations are still possible in collaboration with the Dortmund operating company.

Since 2011 Air Train International has been marketing the system in China and as of May 2013 there are proposals to build lines in Shanghai and Wenzhou. A number of other Chinese cities are also studying the system.
