Rail News Home MOW May 2017 Rail News: MOW Progress Rail offers a range of special trackwork, including flange-bearing crossing diamonds.Photo – Progress Rail By Michael PopkeRailroads continue to ask suppliers of special trackwork components to make their offerings easier and safer to install, and to last longer — be they turnouts, switch point guards, insulated joints, frogs or other products.“The main emphasis has been on reducing the impact put on trackwork that leads to degradation of components,” says Scot Campbell, director of Class I sales in the Engineering and Track Services Division of
Progress Rail, which is field testing what the company believes is a more efficient rail-welding technique.“Railroads need us to keep getting better,” adds Ken Ouelette, vice president of marketing for special trackwork supplier
voestalpine Nortrak, which has made improvements to products and facilities over the past year. “They want to see products that last longer and are easier to install.”And freight railroads likely will want more of them this year, some suppliers say.“We anticipate things will pick up from last year, when there was a bit of a downturn in the freight market,” Ouelette says.Progressive Railroading recently contacted suppliers of special trackwork to learn about their latest product offerings and the trends that impact that market sector. Five special trackwork suppliers responded, either by phone or email. Their edited responses follow.Turnout geometry and flange-bearing technologyThe expansion of
Atlantic Track’s facilities in recent years — including ones in Memphis, Tenn., and St. Clair, Pa. — indicate a commitment to infrastructure technology and capacity, said Jeff Grissom, the company’s vice president of engineering and operations, in an email.In Memphis, Atlantic Track now provides more dedicated, product-specific manufacturing work centers for compromise rails, guard rails and plate work.In St. Clair, the installation of an enhanced electric third rail machining, processing and assembly work center better positions the company to serve the industry, Grissom said.Budgets for special trackwork materials appear steady at most freight railroads, Grissom said, adding that he has detected a slight uptick in Class I activity when it comes to overall maintenance. At the forefront of the special trackwork discussions are issues of turnout geometry at the point of switch entry and mainline speeds through turnouts, Grissom said.The industry also is working to better define the parameters for full-flange bearing crossings and their ideal usage as it pertains to crossing angle and signalization within heavy-haul applications, he added.“Flange-bearing technology has been around for decades in transit to eliminate that ‘ticka-tacka, ticka-tacka’ pounding of the train against the ties,” he said. “Now it’s evolving in heavy-haul applications, too.”Wanted: highly reliable insulated rail jointsMeanwhile,
L.B. Foster Co. notes a “continuing drive by the rail industry for long-lasting, highly reliable insulated rail joints as a key requirement for their special trackwork, as well as for mainline track,” said Sid Shue, general manager of the Allegheny Rail Products division of L.B. Foster, in an email.Shown: a premium Class I design turnoutAtlantic Track
L.B. Foster, which designs and manufactures high-performance insulated rail joints for use in special trackwork, collaborates with heavy-haul railroads and transit agencies to design the company’s insulated rail joints according to their needs, Shue added.
The company’s products include double rail joints for turnouts and crossing diamonds, insulated joints for girder rail profiles, U69/U33 guardrails and transition insulated joints. L.B. Foster’s special trackwork insulated rail joints can be furnished in bonded or poly kit form, plug form, or preassembled to customer-furnished prefabricated or machined rails.
