FFB Slab Track Bögl Progress is built on ideas.

Johann Bögl Shareholder Since two decades, Max Bögl is engaged in trendsetting development and construction of advanced, maintenance-free and durable, ballastless tracks made of prefabricated parts for slab track systems. Permanent developments and experiences gained from realized high-speed projects as well as suggestions and wishes of customers have led to an e ­ xtension of our company know-how and to the completion of our systems. Proudly we can say that we are now in a position to offer a complete range of track solutions accounting for all issues and boundary conditions of modern...

Scope of services Due to its versatility, the Max Bögl Group is able to execute turnkey projects from slab tracks of underground/suburban railways to reconstruction routes to high-speed lines. For the manufacture of the FFB slab track we offer the following services: Heavy good transport Freight traffic Planning Max Bögl has developed planning software for the FF Bögl system which generates an installation plan from the trackgeometric project containing all relevant data for the slab track. These are the basis for the entire logistics – that is production, stocking, transport and...

Technology transfer Quality management We have a team of skilled experts who will assist and advise you in the implementation of your projects by means of our technology. Within the task of a technology transfer we supply for our FFB product a complete compendium with work and test instructions for the manufacture of track slabs and their assembly. In especially adjusted training courses, our customers get all information which they need for the planning, execution and quality control of the FFB. Our practice-oriented experts are glad to accompany and advise you during the execution. In...

This construction method leads to a homogenous trackway with a good long-term behaviour. The system can be used on earth structures, in...

Technical data of the FF Bögl System: Construction height (from OK THB to OK rails): Slab length (System length: nominal 6.5 m): Slab width: Slab height: Rail supports: 10 pairs per slab; spacing 650 mm transverse displacement. The longitudinal coupling counteracts the so-called “whipping effect”, which is a warping of the slab ends due to thermal differences. A characteristic feature of the slab tracks are the predetermined breaking points that are arranged between the rail support points. This will prevent an uncontrolled crack development. In order to drain the surface water, every slab...

Switch slab Concrete base layer Blinding layer FF Bögl Switches & Turnouts Based on the idea to implement railway lines without using a cast-in track panel, but rather by means of prefabricated slabs, the Max Bögl Group has developed a system for gauge change devices. From the conventional turnout sleeper plan of the switch manufacturer, a slab installa­ tion plan is generated. The slab dimensions are, on the one hand, dependent on economic transport sizes and weights, and mechanical and electrical facilities have to be taken into consideration on the other hand. Due to the switch geometry,...

and is reinforced. Reinforcement stirrups at the bottom side of the precast slabs for switches & turnouts, which are anchored with the undercast concrete, ensure that their position is secured. Assembly of the precast slabs for switches & turnouts takes place without turnout rails and accessory. Exact fit of the rail fastenings requires no adjustment later on. The complete switch, including all accessory parts, is only mounted after the precast slabs for switches & turnouts have been undercast. That way, no switch components are soiled or damaged. In contrast to conventional assembly,...
