We measure your rails during grinding operations at speeds of up to 80 km/h (on mainline routes) without disrupting the timetable or closing any tracks. The results are presented to you through the App, which displays a diagram of your rail network and uses a traffic light system to evaluate its condition.

We perform corrective and preventive railway maintenance according to the individual needs of the customer. We particularly rely on comprehensive preventive measures to ensure the overall optimization of track maintenance and life cycle costs. Every extra step contributes to an even more sustainable rail network.

Vibration Analysis ISO 2. The Vibration Analysis Level 2 course is intended for personnel who have at least 12 months vibration analysis experience, and who need to be able to take good data (and decide how the data collector should be set up); analyse a range of fault conditions; and understand balancing and alignment.

Initially, rail grinding programs were almost exclusively corrective/reactive – performed to remove corrugation or surface damage that appeared on the rail. Corrective grinding was a slow and expensive undertaking, requiring multiple passes and the removal of a lot of precious metal from the costliest of a railway's fixed assets. Preventive ...

Corrective grinding is used to achieve the target values for worn or existing longitudinal and cross rail head profiles, to eliminate rail faults, such as laps or corrugations, and to produce special profiles.

As rail grinding practices and technology continue to evolve, Loram will continue to work with customers to evaluate grinding practices in an effort to move from a …

For example, Vossloh Rail Services (VRS) is concentrating its rail-grinding efforts on new generation rail-life management technologies, said Vice President and General Manager Ron Martin in an email.

Rail-grinding machines run over the track to even out irregularities in the rail surface. Track-measurement cars, under their own power or coupled into regular trains, can record all aspects of track alignment and riding quality on moving charts, so that maintenance forces can pinpoint the specific locations needing corrective work.

Track Design Handbook for Light Rail Transit, Second Edition 14-16 Many light rail systems in Europe have specially equipped rail vehicles for performing preventative maintenance rail grinding. These cars are often older high-floor articulated vehicles that are no longer being used for passenger service.

The Haramain High Speed Rail project also known as the "Western Railway" or "Mecca-Medina high speed railway", is a 453.0 kilometers (281.5 mi) (449.2 kilometers of main line, plus a branch connection to KAIA Airport: 3.75) high-speed inter-city rail transport system under construction in …

They are compatible with all international track gauges (light rail and standard gauge) and can be on-railed and off-railed very quickly. Flexis can fulfill the all the maintenance requirements of a turnout: everything from the initial removal of mill-scale to preventive grinding and the removal of defects such as skid spots, head checks and ...

The San Diego Metropolitan Transit System (SDMTS) uses optical rail measurement after rail grinding, which may in fact be rail profile inspection rather than rail defect inspection. 3.2.3 Constraints and Challenges Agencies were also surveyed on the constraints and challenges they face when testing.

Services include the design and construction of light rail, heavy rail, signalling, track and station works, rail safety technology, bridges and roads. We are currently seeking a Track Superintendent to join our team on a Full-time Permanent basis working on a FIFO arrangement in the North West of Western Australia.

Pre- and post-grind profile measurements in Fig. 20.6 (made with a Miniprof instrument, Section 20.3.3) show metal removal around the crown of the high rail in a curve that has been ground (four passes with a 32-stone machine) at an interval of about 25MGT to treat RCF.There is a minimum of about 0.2 mm of metal removal at the rail centre, with slightly …
