Rail track insert assembly for use between rails and adjacent road surfaces in a road-level rail bed comprising a first resiliently flexible elongate insert member contoured to and sealingly engaging with each of the rail-side and guage-side of each of the rails and a second rigid panel member sealingly engaging with each of the first rail insert members at a planar generally vertical or moderately canted slip plane at their interface, to accomodate vertical movement of the rail in response to the passage of rail car wheels, while sealing against intrusion of surface water and detritus. An elongated channel defined in the under surface of each of the insert members accomodates rail clips securing the rail to the underlying track bed.
Ensemble rapporté pour voie ferrée à utiliser entre les rails et près du revêtement routier, aux traverses à niveau, comprenant un premier élément rapporté allongé et élastiquement flexible profilé pour s'adapter de façon étanche aux côtés intérieur et extérieur de chacun des rails et un deuxième élément à panneau rigide se mettant en prise de façon étanche sur chacun des premiers éléments rapportés des rails suivant un plan généralement vertical ou modérément incliné à leur interface, dans le but de permettre le mouvement vertical des rails au passage des roues de véhicules, tout en assurant l'étanchéité contre l'intrusion d'eau superficielle et de détritus. Une rainure allongée en dessous de chacun des éléments rapportés loge les attaches de rails qui assujettissent les rails à l'assise sous-jacente.
