Non-uniform rational B-spline (NURBS) curves are combined with the Kriging model to present a prediction method of the rail grinding profile for a grinding train. As a worn rail profile is a free-form curve, the parameterized model of a rail profile is constructed by using the cubic NURBS curve. Taking the removed area of the rail profile cross-section by grinding as …
Profile Grinding Goals • Top of rail should never have a radius less than 8" – Reduced running band can result in high stresses and rail surface fatigue (spalling) – Running band should be between 1 1/4 and 1‐3/4 inch on all rails • Reduce plastic deformation and metal surface fatigue
Based on this topological structure, the virtual prototype model of the rail vehicle was built using SIMPACK, and a three-dimensional (3D) model of the prototype was constructed as …

The grinding: The rail after grinding. Note the marks on the outside of the rail. A picture showing the grinding marks left on the head. The good news is that it didn't set fire to anything, although I'm glad that the man in the rear cab was using the fire hose to douse any timber work as he past.

Grinding and Milling are Essential for Rail Quality. 2009123&ensp·&enspAfter intensive intrack testing with a prototype device, six Speno grinding machines have been fitted with the companys Headcheck Grinding Scanner.
Preventive grinding assures generally good rail surface conditions -Supervision is required to check the results -Cyclic grinding with only partial damage removal may mask deeper damage (until spalling occurs) -Local defect development needs to be addressed -Corrective grinding complements preventive work - preceding preventive work
An Intelligent Framework and Prototype for Autonomous Maintenance Planning in the Rail Industry. January 2015; ... rail grinding is used into to ad dress defects such .
Oscillating grinding is recommended especially for areas prone to developing rail defects. Examples include stations or stops where waves form or other "hotspots" where corrugations occur. The standard-gauge ATMO prototype employs a water- cooled, sound-insulated 100 kW diesel engine with exhaust after-treatment.
LORAM Rail Grinding Train Posted by Anonymous on Monday, May 1, 2006 3:35 PM Here are some pics I snapped of a LORAM rail grinding train in action, near where I work.

Up till now that could be seen as fine, but with update 13 we see not only more grind, but extension of the grind in the Solar Rails by adding forced time restriction, Argon Crystals, which create a time-sensitive grind, the relegation of an actual boss fight to be grind restricted (Vay Hek), the removal of existing systems entirely (charge attacks), and the implementation of a …

Vibration grinding is recommended for areas prone to the development of rail defects, for example, adjacent to stopping points. The prototype of the machine is equipped with a 100 kW water-cooled diesel engine, improved sound insulation and an additional exhaust gas cleaning system.
sometimes the rail gets uneven from having millions of tons of weight passing over it.........grinding it gets rid of any uneveness and returns the profile to the head of the rail............you can tell when rails have been ground when a passing train makes a loud humming sound ........sometimes you can actually see corrugations in the head of …
Wheel Re-Profiling and Rail Grinding Strategies on Wiener Linien (Part 1 of 2) By Edgar Fischmeister, Markus Ossberger, Roman Pongracz and Paul Mittermayr • October, 2007. Rail grinding and wheel re-profiling are essential elements of track and vehicle maintenance. These maintenance procedures have been shown to play a major role in the ...
4 axles, 10 grinding head grinder. The grinding train is fixed to the chassis and each grinding head has 1/2 stud lateral freedom on each side. Unfortunately, it wasn't enough and this prototype can take neither curves, nor points. I tried another approach by using only 4 grinding heads, and bringing the bogies closer by using the middle hole on each extremities.
