General information concerning
edilon)(sedra Filler Blocks
edilon)(sedra SDS and SDS-M type for tram tracks
Elastomeric rail web Filler Blocks are invented and patented by edilon)(sedra. edilon)(sedra is offering a wide range of Filler
Block designs for many different types of grooved and vignol rails and for various application fields such as in-street running
track, turf track, special track work, depots, level crossings as well as for crane tracks.
All kind of installation accessories, well tested and proven, to perfectly insulate/isolate the track, such as rail foot profiles, tiebar isolation profiles, factory isolated tie-bars, plastic cover caps, rail anchors, mats and strips, electrical insulating adhesives
and pasty fillers and many others are provided by edilon)(sedra.
