By Norman Hooper • July 2010 See Part 1. Experience has shown that an efficient and cost-effective rail grinding program requires attention to basic track inspection and maintenance procedures. This includes attention to “hot spots,” such as joints, welds and road crossings. Figure 1 shows a rail joint at the end …
By Mike Roney • July, 2009 Canadian Pacific has taken a unique approach to reducing the stress state in its western corridor. The approach includes the implementation of distributed power and the implementation of friction management. It also includes examination of their combined effects — something that is relatively new. Looking at …
By Norman Hooper • January 2010 It behooves railways to periodically review tie, fastener and surfacing maintenance practices, particularly as they relate to the planning and quality of rail grinding procedures. The use of technology, enhanced inspections, regular grinding cycles and friction modification can improve rail surface quality. The safety rationale …
By Mike Gilliam and Russell Rohlfs • July 2010 The Union Pacific Railway has 30,000 mainline miles of track over 23, primarily, western states. It has more than 6,500 miles of curves, which require significant maintenance efforts, such as rail grinding and lubrication. It’s a challenge to manage the rail assets, …
