摘要:
A railroad flangeway filler for a freight railroad and grade crossing comprises a section of foamed polyurethane inserted into a gap in the freight railroad and grade crossing. Preferably, the filler design has a substantially planar uppermost surface and a hard urethane base. A method for making such flangeway fillers is also disclosed.
摘要:
A rail assembly including one or more rail bodies formed for supporting rolling engagement of a train wheel thereover, the rolling engagement generating vibrations in the rail body. The rail assembly includes one or more boots formed for attachment to the rail body to substantially electrically isolate the rail body relative to ground material. The boot includes a chamber wall for at least partially defining a chamber between the rail body and the chamber wall when the boot is attached to the rail body. The rail assembly also includes one or more inserts positionable in the chamber, at least a part of the vibrations being transmittable to the insert when the insert is positioned in the chamber, for dissipation of at least a proportion of the part of the vibrations in the insert.

A method and apparatus for constructing railways for a rubber-wheeled AGT system are provided. The method includes forming guideways, along which guide rollers of a light rail vehicle moves when the light rail vehicle runs along railways and forming, using a pressing unit of a finisher, the railways applied with concrete such that the railways have a same trace as the guideways by moving a finisher along the guideways. The apparatus includes a vehicle that is provided with rollers to run along guideways installed on vertical walls of a road bed and a pressing unit that is disposed under the vehicle to make lateral and longitudinal traces of railways correspond to lateral and longitudinal traces of the guideways by pressing and forming a top surface of railway concrete during the running along the guideways.
摘要:
A rail which has secured to it a composite body for absorbing vibrational energy whereby to reduce noise generated by vehicular traffic on the rail. The composite body comprises a visco-elastic damping medium 5 bonded to, and sandwiched between, both the rail and a constraining member, e.g. a steel strip 6, substantially stiffer in tension than the damping medium.
摘要:
A compound railroad track wherein the head rail is easily replaceable without replacement of the supports, which comprise two extruded mirror-image L-shaped members, periodically spaced U-shaped separators, and a base plate, all suitably bolted and welded together.
摘要:
A process for producing rails with a lateral guide surface, together with or without an inner or running edge, and/or a bearing or running surface which is highly resistant to wear and tear, which comprises A. PREPARING THE LATERAL GUIDE SURFACE, WITH OR WITHOUT AN INNER OR RUNNING EDGE, AND/OR BEARING SURFACE BY THE FORMATION OF A SUBSTANTIALLY RECTANGULAR RECESS THEREIN, WHEREBY A1. IN THE CASE OF THE PREPARATION OF THE LATERAL GUIDE SURFACE TOGETHER WITH AN INNER OR RUNNING EDGE, THE RECTANGULAR RECESS HAS A HEIGHT OF AT LEAST 10 MM AND MAXIMALLY 34 MM, AND A WIDTH OF AT LEAST 3 MM AND MAXIMALLY 10 MM, AND A2. IN THE CASE OF THE PREPARATION OF THE RUNNING OR BEARING SURFACE, AT LEAST ONE RECESS POSITIONED ESSENTIALLY PARALLEL TO THE LONGITUDINAL RAIL AXIS HAS A HEIGHT OF AT LEAST 3 MM AND MAXIMALLY 8 MM, AND A WIDTH OF AT LEAST 10 MM AND MAXIMALLY 30 MM, B. FILLING THE RECESSES BY WELDING ON A WELDING MATERIAL HAVING THE FOLLOWING COMPOSITION (IN PERCENT):
摘要:
A composite laminated construction track for use in a relatively low cost and economically operated high speed passenger transportation system wherein motive vehicles are coupled to provide transportation for large numbers of people. A powered main vehicle that may be one unit or more than one coupled unit is provided to travel between terminal stations and detachable passenger ferrying auxiliary vehicles are used to transport passengers and their baggage between the main vehicle and intermediate loading or unloading stations. Operation of the independently powered motive vehicles is coordinated through a computer system, sensing units on the vehicles provide signals for coupling control and specially constructed tracks and track switching insure safe operation even at very high speeds.
