2019-12-9 stock rail. This prevents the opportunity for wheel climb derailments. y When handling switches always check the switch point and notify CSX if there is a gap observed between the switch point and stock rail. Check it, line it, check it. y Ties are recommended for long term, as gage rods should not be used as a permanent solution.

In 1998, BNSF started transitioning their rail from a corrective state of wear and surface fatigue back to the favored preventive state. The National Research Council of Canada developed a unique rail-grinding strategy called Preventive-Gradual to effect the transition. This strategy was shown to extend rail life through reduced wear. The rail was restored to a superior surface condition ...

2021-6-3 Rail grinding has been an important component of the BNSF rail maintenance program for the last 40 years [1]. The BN began grinding in the 1960’s to remove corrugation and head flow. By 1987 BN’s grinding program had evolved to a corrective profile grinding strategy on curves at 31.5 million gross tonnes (mgt) (35 million gross tons) ...

2019-4-19 The rail grinder, a train-sized machine that grinds away surface conditions in the rail that can become defects, inevitably spews sparks as it completes its work. The rain acts as an easy and cost-free solution to any errant sparks that may leap into nearby grasses or brush. Employing the rail grinder for preventative maintenance is an ...
