Translohr

Translohr is a technical implementation concept for urban transport systems, operate at the two-way trolley buses on its own routes and track permanently guided by center-mounted rails. The generic name for such systems is tramway sur pneumatiques, French for tram on rubber wheels. Alternative names are rubber-tyred tram or trolleybus track. Sometimes the vehicles are classified as road vehicles, which is why they need license plates in Shanghai. Externally, they resemble the other hand, more modern low-floor trams.

History

Translohr was developed by the French company Lohr Industrie and on 11 June 2012, Alstom and the fund stratégique d' investissement sold.

Concept

The advantages of Translohr system over conventional trams are smaller minimum radii and thus a smaller footprint and tighter passable arches. Likewise, stronger potential gradients and lower construction costs. Criticism is often that the system the disadvantages of the tram (high cost of infrastructure, own route required) combined with those of the bus ( instead emphasized race turf track necessary higher energy consumption and taking up more space for the wheels in the car ).

Principle of operation

The railcars are articulated vehicles, the only - run track guided by a central rail - even at the depot and in the workshop. The tracking is performed by two inclined wheels with wheel flange, which relate to each other at an angle of 90 degrees and laterally engage the guide rail. The floor height is 25 inches above the road surface.

The vehicles have single-pole single-arm pantograph and drive with 750 V DC, the return current flows through the guide rail. If necessary, they can be used in multiple traction. The wheels are - similar to the Ultra Low Floor tram - housed in the joint portals, which both the envelope of the car has been optimized and a more flexible design of the interior allowed without pedestals. The speed limit is 70 kilometers per hour. In addition, the Trans Lohr has a battery backup drive. With this he can travel with malfunctions shorter distances without power from the catenary. However, he is not free steerable. The vehicles produced to date are only 2.20 meters wide. Your seat allocation is therefore 2 1, with wider seats are used in the joints. Manufacturer side, the Translohr is also offered with 2.40 or 2.65 meter wide car bodies. The following configurations are possible (capacity four persons per square meter ):

  • STE3: three-part, 25 feet long, 127 people
  • STE4: four-piece, 32 feet long, 170 people
  • STE5: five-piece, 39 feet long, 213 persons who have not yet realized
  • STE6: six-part, 46 feet long, 255 persons, not yet realized - planned from 2014
  • Two coupled STE3: 51 meters long, 254 persons, not yet implemented

So far bidirectional vehicles were produced exclusively the Translohr but also offered as a one-way vehicle.

Farms

So far, six went Translohr routes in operation on which operate together 94 vehicles. Two other systems with again 35 units are under construction. None of the eight future systems consists of more than one line:
