S&C bearers made using the Rutgers and Polywood Technologies have been installed in a variety of locations around the world, and have proven to be cost-competitive against hardwood, especially over the life-cycle of a switch. Turnout bearers made using the Rutgers and Polywood Technologies provide a high quality and consistent product which are available in lengths (up to 5m) which are difficult to obtain in hardwood, and with the correct FSC Chain of Custody Certification.
Bearers made using the Rutgers and Polywood Technologies have been installed in various locations in Australia in turnout applications. Following favourable initial trail orders and in-track testing, the sleepers have been installed to replace wood sleepers on rail lines that have been damaged due rot and insects.
New Zealand’s Kiwi Rail has installed sleepers made using the Rutgers and Polywood Technologies on critical application areas such as turnout switch-sets and transoms (sleepers installed on open deck bridges). The sleepers were chosen because of their durability in challenging track conditions, including fluctuating weather conditions and environmental credentials.
Sleepers made using the Rutgers and Polywood Technologies for use in road crossings, where the transit line’s tracks intersect with roads. Due to the environmental impact of wooden creosote sleepers, transit operators started experimenting with composite sleepers in road crossing areas in 2009. During the evaluation period, sleepers made using the Rutgers and Polywood Technologies demonstrated tie plate and screw spikes acceptance, and road salts had no effect on their longevity
A Canadaian based Light Rail Transit Authority has installed sleepers made using the Rutgers and Polywood Technologies that have been used for road crossing applications where the transit line’s rail tracks intersect with roads. During the long winter season salt is regularly used for road safety due to heavy snowfall and ice formation. While salt entrapment under road crossings can damage and reduce the life of traditional wood sleepers, sleepers made using the Rutgers and Polywood Technologies are completely impervious to salt. Freeze-thaw cycles are also common, where water gets into wood, freezes, and then thaws again, leading to a weakening and rapid deterioration of traditional wood sleepers. In manufacturing these sleepers, more than 68 tonnes of plastic were taken out of the landfill stream and converted into high-performance sleepers.
San Francisco Bay Area Rapid Transit has installed Switch Set Sleepers made using the Rutgers and Polywood Technologies, ranging from 3.5m to 6.7m in length. One of the main factors to install composite sleepers is the 52 tonnes of plastic waste recycled and diverted from landfills.
A major international freight line has installed sleepers made using the Rutgers and Polywood Technologies on its bridges due to the durability, lightness and life-cycle value. Sleepers made using the Rutgers and Polywood Technologies were used for replacement of wood timbers on bridges, turnout switch-sets and transoms, including sleepers installed on open bridges.
Dallas Area Rapid Transit (DART) has installed sleepers made using the Rutgers and Polywood Technologies for use in the Trinity Railway Express (TRE) that connects Dallas and Fort Worth. TRE has installed the sleepers on main line rail sleepers as well as specialty sleepers for use in crossings, turnouts and bridges. This use of composite sleepers eliminated the need to cut down more than 2,500 trees and diverted 453 tonnes of plastic from landfill.
