RORUNNER System KVB

The system comprises

• 2 RORUNNER Track Vehicle (54.17)
• with crane and on-board auxiliary driver's cabin for push-pull operation
• 1 RORUNNER Track Vehicle without crane (54.17)
• 2 ROTRAILER Low-Loading Wagons (55.70/2) with various platform installations
• 1 ROTRAILER Long Rail Vehicle (55.70/3) for up to 18 m rails
• 1 ROTRAILER Ballast Transport Wagon (55.70/4)
• 1 ROTRAILER (55.70/5)
  with high-pressure jetting and vacuum system for underground systems
   

With the eight vehicles, up to 16 different train combinations can be formed; these are designed for mixed operations according to EBON/A and BOStrab and can cover all transport tasks in urban maintenance operations.

Payload:

• RORUNNER w/ crane: 2 t
• RORUNNER w/o crane: 3 t

ROTRAILER payload: up to 18 t

Compared to previous methods, the system will transport greater loads in less time:

• The general-purpose trailers carry sleepers and construction materials to platforms all of types - including low loading ones - occurring in the network.
• Heavy components such as ticket vending machines, groups of seats or transformers are taken straight to the destination platform.
• Cable reels, escalators, control cabinets, cleaning equipment, construction machinery
• Rails up to 18 metres long
• As opposed to just side tipping, up to 17 t of ballast can now also be dumped and spread centrally.

In a nutshell, you will need fewer trips for more material.

• Filler element and side walls
• Filler element and deflector walls
• Filler element, side and deflector walls
• Side walls and cable drum block
• Detachable skip

Maintenance in moving urban traffic puts high demands on the vehicles' acceleration and braking capabilities: They should be able to stop abruptly for other road users at any time. All wagons feature direct and indirect pneumatic brake systems, spring actuators (parking brake), magnetic track brakes and anti-skid / wheel slide protection.

Rapid braking essentially depends on a good view, particularly if the train is travelling at top speed (60 km/h) itself. The track vehicle features large windows on all sides and a pivoting driver's seat which provides the operator an unrestricted view of the platform edge, zebra crossings, signals and people or cars on the roadside. If used separately, the track vehicle's rear cabin gives a full view of what's happening on-site.

The high utilisation of the urban railways during the week and in some cases transport operating also throughout the night at weekends are a burden for the public networks and pose new challenges for infrastructure operators: Maintenance requirement is increasing, the available time slots available for it are decreasing.

Up to 90% of the urban maintenance work takes place during the night when the trains are not operating; on average a mere two to four hours are available for this maintenance work.

Thus, infrastructure work has to be better organised and faster to ensure that highly frequented lines remain available. There is little time for ad-hoc deployment due to broken rails or line damage. Therefore continuous maintenance and timely error correction are the prerequisites for fault-free operation.
