A railway tie being constructed of an engineered cementitious composite (ECC) material having: (1) a minimum of 2% tensile ductility of ECC, (2) complete absence of alkali-silica reaction (ASR), (3) high fatigue resistance of ECC at least five times that of normal concrete, (4) self-healing ability of ECC requiring only water and air, and (5) customization of ECC for lower stiffness in the tie (60% that of normal concrete) and higher abrasion resistance in the seat (three times that of normal concrete).
146	BAHNSCHWELLE	PCT/EP2007/060140	2007-09-25	WO2009046748A1	2009-04-16	FRENZEL, Jürgen; FRENZEL, Tim
Die Bahnschwelle (10) ist mit einem Schwellenkörper (12) versehen, der an seinen gegenüberliegenden Enden jeweils einen Schienenauflagebereich (16) aufweist, innerhalb derer der Schwellenkörper (12) verbreitert ist. In jedem Schienenauflagebereich (16) ist mittels eines an einen Schienenfuß angreifbaren Niederhalteelements (28) eine Schiene (24) fixierbar. Jeder Schienenauflagebereich (16) weist drei in Erstreckung der Schiene (24) nebeneinanderliegende Schienenauflageflächen (18) auf. Zwischen und oberhalb zumindest eines Teilbereichs jeweils benachbarter Schienenauflageflächen (18) jedes Schienenauflagebereichs (16) ist mindestens ein Niederhalteelement (28) angeordnet. Der Schwellenkörper (12) ist innerhalb jedes Schienenauflagebereichs (16) beidseitig der Zwischenräume zwischen benachbarten Schienenauflageflächen (18) frei von Versteifungselementen.
147	SHELL CROSS-MEMBER SYSTEM AND RAILWAY SECTION INCLUDING SUCH A SYSTEM	US15460932	2017-03-16	US20170268179A1	2017-09-21	Lise PESQUEUX; Arnaud LOAEC
This cross-member system with shell (10) for a railroad track, intended to be wedged in an apron of the railroad track, of the type including a cross-member (12) having a lower face (20), and an upper face (22) that is intended to receive a rail fastening system (14), and a shell, is characterized in that the shell envelops substantially the entire cross-member so as to define an inner volume for receiving the cross-member that is sealed against outside attacks.
148	Reinforced concrete tie with embedded rail clamp means	US742190	1976-11-16	US4090665A	1978-05-23	Milton E. Schlesener
An assembly for fastening of railroad track incorporating a steel reinforced concrete tie with vertical thread steel sleeves welded to a reinforcement truss embedded in the concrete tie to which sleeves, track bolt assemblies may be threadably joined. A track bolt assembly includes a pair of hollow male threaded plugs, each threaded to a female thread in the opposed ends of a sleeve to retain a nut that is biased by a compression spring in the sleeve, to which nut, a track screw mounted to a hold-down block is engaged. With the hold-down block fixed against a track rail flange, the screw may be tightened in the nut of the sleeve to a pre-set tensile load as determined by the compression spring.
