Of Historical Interest

Cabintaxi - a German Personal Rapid Transit (PRT) technology that features both supported and suspended vehicles, of several sizes. It was developed in the 1970's but detailed information about it is currently available from an American company.

Cabinlift - a technology that has been in continuous operation since 1975, connecting two hospitals in Germany.
As of November, 2010, the functions of the hospitals has been changed and the system has been shut down, as it is no longer needed to connect the hospitals.

ELAN - a German "skyhook" concept developed in the late 60's

Flyda - an urban mass transit monobeam concept devised in the U.K. in the early 1980s that provides for two-way travel on one guideway, elevated, at grade or in tunnel. Flyda is no longer in business. It's patents have expired and are now in the public domain. ('07)

ROMAG - a suspended (or supported) GRT-scale technology that used linear induction motors for propulsion and maglev for suspension, developed by the Rohr Corporation, in the early 1970s. 


Currently Operating

POMA technologies - includes several cable-supported systems

SIPEM (aka H-Bahn 21) - a German GRT technology that is operating at Dortmund University in Germany and  at Duesseldorf International Airport, where it is known as SkyTrain.  However, so far as is known, SIPEM is no longer offered as a product by Siemens.

Wuppertal Monorail - started operating in 1901 in Germany - now carries around 50,000 passengers per day on a 13.3 km line. Centenary celebration was held in 2001!

Under Active Development

Note: For some current and very innovative thinking about the design of suspended PRT systems, see Dan's OpenPRTSpecs blogspot

Aerobus - a suspended mass rapid transit technology developed orginally in Switzerland and now being marketed by a company in Houston, Texas, USA. Project now under construction in China, begun in 2004. Current information is unavailable and it is not know if the application in China is operational or not.

Beamways - a suspended small vehicle being developed in Sweden

Beem Car - a GRT suspended vehicle being developed in the U.K. - to use composite materials

Flyway - an effort by SwedeTrack in Sweden to develop and deploy a suspended vehicle that can be lowered to the ground, thus avoiding the need for station structures - a large, lively and informative website - has not been updated recently.

Higherway Transport Research - a suspended, dualmode/PRT concept that shows great promise. Similar to Flyway in many respects.

Hytran - a suspended monorail being developed by a group in Illinois.

JPods - a very small suspended system being developed in Minneapolis - very good slide show at their website

Metrino-PRT - small vehicles suspended from an elevated guideway, being developed in Poland, features a unique method of switching (aka cross-overs). Updated video now available

  Monomobile - a dual-mode concept that uses small electric cars that can be connected to an overhead rail for movement in a suspended mode. Test track in the Cincinnati area now being planned.




MonoMetro - a suspended monorail being developed in the U.K. - extensive, well-illustrated website. Contract for a project in Saudi Arabia was signed in May, 2008, but is currently inactive

Shweeb - suspended small vehicles (capsules) using human-powered propulsion on a monorail-type guideway, from New Zealand, awarded $1 M prize from Google in 2010

SkyCabs - a small group system that uses a monobeam for two-way travel, now being developed in New Zealand

SkyRide Technology - suspended, small, human-powered, open-air vehicles using a monorail-type guideway

Sky Train - an overhead suspended light rail technology being developed in Clearwater, Florida 

Sky Tram - a suspended mass transit concept that would make use of old airplane fuselages

SkyTrolley - a bus suspended from a steel box beam for mass transit applications, being developed in British Columbia, Canada

Transcar - a small suspended vehicle now being developed in Russia (in Russian only but some
illustrations are provided) new3.gif (1292 bytes)

  Unimodal (formerly know as the People Pod, currently as SkyTran) - a maglev, high speed, personal transportation. A full-scale vehicle and test track are being built, as of 2014 in Tel Aviv, Israel. If successful, expansion is expected.


Zhonghua-06 -- a small, suspended, maglev system now under development in Dalian, China

Conceptual, More-or-Less Active or Dormant

Computerized Ultra Light Overhead Rail (CULOR) - a suspended vehicle system concept still in an early stage of its development.

Electronic Guideway System (EGS) - a "quadmode" small, suspended vehicle concept 

Integrated Transportation System (InTransSys) - a suspended pallet system (dual mode) capable of carrying a variety of vehicle types and containers. Inactive - was being developed in Colorado, USA.

MIX - a small vehicle system that operates on conventional streets for short trips and can also be suspended from a cable for longer distance travel - designed to be a combination of the bicycle, PRT and electric car.  No longer active.

Pathfinder - a suspended personal rapid transit system (PRT) that was being developed by a group in Detroit, MI, USA. Not currently active (November 2003)

Project 21 - a monobeam transit technology that allows two-way travel on one guideway. A quarter-scale operating model was completed in July, 1996.

Spanish suspended PRT, US Patent 8735865, hgh capacity, steerable small pods, conceptual only, as of August, 2013


Suggestions for improvement, extension or revision are welcome.
