(Testing of rail is currently able to be done at 80 km per hour with a Speno US-6 Ultrasonics train) Another need for the future is a complete rail inspection system. A step in this direction is a deeper investigation of the rail by using low-frequency eddy currents.
Guard rails at Diêu Trì railway station, Vietnam This curved track in Myanmar, near Pekon, includes a guard rail on the inside rail of the curve. In rail transport, guard rails or check rails are rails used in the construction of the track, placed parallel to regular running rail to keep the wheels of rolling stock in alignment to prevent derailment.
Looks for hunting oscillation of the trucks or wheelset; a lateral movement in the gauge of the track, like drifting back and forth in a lane of traffic. This action can increase above a certain speed to the point the wheel flanges impact the rails, potentially causing damage to both.
A track geometry car (also known as a track recording car) is an automated track inspection vehicle on a rail transport system used to test several parameters of the track geometry without obstructing normal railroad operations. Some of the parameters generally measured include position, curvature, alignment of the track, smoothness, and the ...
tracking of equipped train location and track occupancies via the data link, and unequipped train location and track occupancies via voice reports and manual entry; speed enforcement for equipped trains; enforcement of limits of authority for equipped trains; pacing for fuel economy for equipped trains; monitoring and control of wayside systems;
A railway track (CwthE and UIC terminology) or railroad track (NAmE), also known as permanent way (CwthE) [1] or "P Way" BrE [2] and Indian English), is the structure on a railway or railroad consisting of the rails, fasteners, sleepers (railroad ties in American English) and ballast (or slab track), plus the underlying subgrade.
OpenRailwayMap contains data for railway line positions, as well as the following information about them: track type (i.e. bridge, tunnel, regular line); track line type and current use (i.e. main, branch, yard; construction, disused, abandoned); max rail speeds; train protection; track electrification and track voltage if applicable; and track gauge.
Network Rail standards. Documents that specify requirements directed towards securing the safe and efficient operation of the rail infrastructure. Track standards were supported by the 'Business Critical Rules Programme' pilot in June 2012. The Sectional Appendix is the definitive source of information on UK railway infrastructure for specific ...
