LRB Light Rail Bögl Progress is built on ideas.

Johann Bögl Partner The unstoppable growth of the world population makes especially metropolises swell. Already today, there are 400 cities worldwide with more than one million inhabitants each. This development will pose substantial challenges to mega cities – especially with regard to managing inner-city traffic. Therefore, this results in a renaissance of the tram around the globe. In many cities, new tramlines are being built. Small and out­ dated tramlines are currently being reconstructed or extended. Awarding authorities and planning agencies are facing the tasks to include modern and...

Business activities As an integral part of the cityscape, railways make it necessary to consider various aspects. Therefore, the Max Bögl Group offers a wide range of slab track systems for railway-bound local public transport. The LRB pro­ duct line ranges from directly driven systems in different sur­ face design to ecological lawn track routes up to track switches and individual special solutions. The following services are available to our customers. Planning Max Bögl has developed software for the LRB system which generates an installation plan from the track-geometric pro­ ject containing...

LRB system description The Light Rail Bögl system family consists of the slab tracks which are produced under controlled conditions with integrated mounting parts. Generally, the system is available for all track gauges. The prefabricated slabs are installed on the prepared substructure, adjusted and underpoured using self-compacting concrete. The concrete for the production of the slab tracks is produced according to DIN EN 206. For the transmission of shear force, the prefabricated slabs are combined with each other in butt joints. The rails of any type installed in the rail channel are gauged...

LRB - Light Rail Bogl system variants

Grey Line LRB Grey Line If wheel-rail and heavy wheelrubber traffic systems, i.e. a tram and lorry/bus traffic, coincide on a shareable way, this situation sets highest requirements to a driving surface. For this, the LRB Grey Line system with the directly drivable concrete carriageway is the best possible solution for public transportation. Due to its homogenous, monolithic and simple structure, the LRB Grey Line slab is the ideal system for these demands. What is to be highlighted for this type of driving surface is the variety of design options for the surface regarding patterns, structure...

Black Line LRB Black Line For the common use of trackways through individual and public transport traffic, the LRB Black Line system with asphalt driveway is the ideal solution for the transport company or town planners. Apart from high flexibility, this solution offers well-known Max Bögl quality and a short construction period. This system design accounts for the exposure classes according to DIN EN 206-1/DIN 1045-2. To transmit the side force acting on the rail, to reduce the structure-borne noise and for electrical insulation of the rail, flexible filler blocks are installed on the side of...

Green Line Premium Green Line LRB Green Line Public transport companies and town planners more and more frequently attach importance to unsealed areas in order to avoid adverse effects on urban water supply. With the LRB Green Line system, the whole track route space is vegetated. With this system, the positive characteristics with regard to reduced sound emissions have to be highlighted. The high-quality and positionstable finished part and lead frame combines the advantages of the slab track with ecological and design demands. LRB Green Line is available in two design variants: Green Line:...

LRB TS Concrete elements with project-related dimensions and installation weights are manufactured for the prefabricated switch and turnout system LRB TS. The rail is either supported in a support point distance specified by the points manufacturer or in a continuous way. using CNC milling machines, and they are anchored in the concrete formwork. The LRB switch and turnout elements are delivered to the switch plant for pre-assembly and purchased there from the client after they have been assembled. Completely preassembled with all installation The rail guidance of a switch parts and rails, the...

Silver Line LRB Silver Line Using this system from the LRB family of the Max Bögl Group, operators and planners have special design options available. The slab track surface of the LRB silver line can be made of different materials like con­ crete- or natural block pavement as well as in different format and colours. A custom­ ised adoption to the rail track within the individual city optic is therefore possible. Furthermore, the rail embedded into the PU mass ensures excellent reduction of structure-borne noise. The concrete surface of the rail channel can be matched to the paving cover in terms...

Construction process Installation of the LRB track system basically takes place in the following steps: • Manufacture of the sub­ structure • Preparations, such as survey jobs • Delivery and unloading • recise height adjustment P via integrated spindles • ransverse sealing for the T grouting mass • routing the LRB slabs with G self-compacting concret • ail welding R • ifting the rails into the L rail channel • djustment and fixation A of the rails • ouring all block-outs P and rail channels
