The feature that I wrote for issue 20 is about personal rapid transit. PRT, as it is called, is a mass transportation concept that swaps high-capacity trains for small “pod cars.” These individualized vehicles run on dedicated tracks from origin to destination, bypassing all other stations along the way. Such a system is currently being installed at London’s Heathrow Airport and Foster + Partners is developing a PRT solution for its Masdar City project, but the idea has been around at least since the 1950s. In the late 60s and 70s several prototypes were developed and tested for possible urban application, but—aside from a semi-PRT system installed in Morgantown, West Virginia—none of them were ever realized. The one that came the closest was Cabinentaxi, which was to be rolled out in Hamburg, Germany. A recession in 1980 sank the project, but luckily they made this lovely film before falling into the dustbin of history. Enjoy.
