SLAB INTELLIGENT TRACk VERSATILE IVES AND SOLID EffICIENT

RHOMBERG RAIL

IVES SYNTHESIS Of DESIGN AND CONSTRUCTION EXPERIENCERhomberg Rail can call on years of theoretical and practical know-how in the various types of slab track construction. And the result is IVES, the latest development in ballastless track construction. IVES stands for intelligent, versatile, efficient, solid. All these characteristics are embodied in this integrated concept, which is based on an analysis of the advantages and disadvantages of various long-term tested slab track techniques.

UNIVERSAL APPLICATIONDifferent railway types same track system: TheIVESslabtracksystemcanbeusedforalmostanytype ofpermanentway(standardgauge,rapidtransit,low-orhighspeedrailway).Becauseofitssimpleformofconstruction, anyrequiredmodificationscanbemadequicklyandeasily. Changes to the track configuration easily done by sticking to the basic principles Thesimpledesignoftheprefabricatedconcreteunits, inparticulartheirshapeandprecisedimensions,allows eachcomponenttobespecificallyadjustedtosuitany trackconfiguration.
