The system consists of:
- 2 RORUNNER track motor vehicle (54.17)
with loading crane and integrated auxiliary driver's cab for bi-directional operation - 1 RORUNNER track vehicle without loading crane (54.17)
- 2 ROTRAILER low-floor trailers (55.70/2) with various body variants
- 1 ROTRAILER rail car (55.70/3) for rails up to 18 m
- 1 ROTRAILER gravel transport trailer (55.70/4)
- 1 ROTRAILER trailer (55.70/5)
with high-pressure flushing and vacuum system for subway systems
Up to 16 different train combinations can be formed with the eight vehicles, which are designed for mixed operation according to EBON/A and BO Strab and cover all transport tasks in urban maintenance operations.
Payload:
- RORUNNER with crane 2 t
- RORUNNER without crane 3 t
Payload ROTRAILER up to 18 t
The system transports more loads in a shorter time compared to previous methods:
- Depending on requirements, the universal trailers deliver sleepers and building materials to platforms of all types found in the network, including those in the low-floor area.
- Heavy components such as B. Ticket machines, seating groups and transformers are transported directly to the moving walks
- Cable drums, escalators, control cabinets, cleaning equipment, construction machinery
- Rails up to 18 meters in length
- Up to 17 tons of ballast are unloaded and distributed in the middle of the track area instead of just laterally.
Overall this means fewer trips for more material.
- filling piece and side walls
- Filler and baffles
- Filling piece, side and impact walls
- Side walls and cable drum stand
- skip
Maintenance in flowing city traffic places high demands on the acceleration and braking values of the vehicles: a abrupt stop for other road users must be possible at all times.
All wagons have pneumatic direct and indirect braking systems, spring-loaded parking brakes, magnetic rail brakes and anti-skid and anti-skid protection.
At a maximum speed of the system of 60 km/h it is in its own right good view an essential requirement for quick braking response. The all-round large glass surfaces and the swiveling driver's seat of the GKW give the operator a clear view of the edge of the platform, zebra crossings, signals as well as pedestrians and vehicles standing to the side. If the GKW is used as a single vehicle, the rear cabin offers a full view of what is happening on the construction site.
The high utilization of the city railways on weekdays and the partly continuous night traffic on weekends put a strain on the public networks and present infrastructure operators with new challenges: the need for maintenance is increasing, the available time windows are steadily decreasing.
Up to 90 percent of the inner-city maintenance work takes place during the nightly breaks in operation, with an average of only two to four hours available for this.
Infrastructure work must therefore become faster and more organized so that highly frequented routes remain reliably available. There is little time for ad hoc calls due to broken rails or cable damage, continuous maintenance and timely rectification of defects are the basic requirements for trouble-free operation.
