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 …

The "moving average" of RMS amplitude of corrugation in the 100–300 mm wavelength range on an 800 m grinding site is shown for both rails, with pre-grind and post-grind data superposed. There has been a reduction in exceedence of the 12 μm RMS level from 98% to 0% on the left rail and from 25% to 0% on the right rail, which is better than the 5% …
Plasser & Theurer launches silent rail grinding machine. The Austrian company Plasser & Theurer has released the ATMO (Automatic Track Machine Oscillator) rail sander for public transport and trams. The device has a low noise level during operation, reports Railway Supply magazine with reference to the manufacturer's information.
Plasser & Theurer announces new rail grinding technology. The ATMO (Automatic Track Machine Oscillator) rail grinding trailer was designed and built by Plasser & Theurer as part of Shift2Rail. With Plasser & Theurer's newly developed rail grinding machine for light rail and trams, rail traffic is easy on the ears: trains travel more quietly ...
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 …
With Plasser & Theurer's newly developed rail grinding machine for light rail and trams, rail traffic is easy on the ears: trains travel more quietly on ground rails. The world's first ATMO (Automatic Track Machine Oscillator) was developed as part of Shift2Rail and combines two working methods. An Enhanced Rail Grinding Method
Rail Grinding Loram. Extend the Life of Your Rail Rail grinding is the erstone of virtually every railroad maintenance program. To maximize the life and value of rail assets, precision removal of fatigued metal, restoration of the rail head profile and removal of rail defects are the optimization goals of an effective rail grinding.
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
Rail Grinding Equals Quiet Travelling. With Plasser & Theurer's newly developed rail grinding machine for light rail and trams, rail traffic is easy on the ears: trains travel more quietly on ground rails. The world's first ATMO (Automatic Track Machine Oscillator) was developed as part of Shift2Rail and combines two working methods.
The standard-gauge ATMO prototype employs a water-cooled, sound-insulated 100 kW diesel engine with exhaust after-treatment. The engine provides the required oil pressure. Designed for urban environments The new rail grinding trailer designed for tram networks grinds plain track and turnouts. A power car or road-rail vehicle tows it to the ...
Loram starts rail grinding research with Black & Decker hand grinders and is developed into a small self-propelled rail grinder that could handle spot-maintenance work. 1971. Loram's first tie inserter is built. 1972. Loram introduces the Autosled. 1974. Loram's expansion leads to a new facility in Hamel, MN. 1979.
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.

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.
