Before newly installed or out of use rail that has a visible coating of rust on the rail head as per the photograph is brought into use for train running, the responsible signalling tester must notify the signaller of the extent of the rail being brought into use. This can be either the track circuit(s) affected or the signals/points outside the affected area, making clear to the signaller the ...
· Rail grinding is performed on new rail prior to being placed into service in order to achieve the optimal rail profile of matching an average rail wheel. Additionally, rail grinding is performed at periodic intervals on rail already in service for the purpose of removing imperfections and restoring the rail to its optimal profile. Rail grinding is not performed at set intervals; the frequency ...

A research methodology is proposed for grinding systems, for the example of gear grinding by copying on CNC machine tools. In this approach, the system is characterized in terms of input, state, and output. Methods of modeling, optimization, and control at the production and preproduction stages are described. Analysis is possible on the basis of probabilistic and frequency approaches.
· A mortar bed is the only accepted method for installation of cement board. It should also be noted that the mortar is not intended as an adhesive; it is there to provide continuous support for the board with no voids. It is the fasteners which secure the board to the subfloor. Finally, the underlayment must be fastened according to the manufacturers specifiions. For cementitious backer ...
