Slab Track Field Test and Demonstration Program for Shared Freight and High Speed Passenger Service

In July 2003, two types of concrete slab track were constructed to Class 9 Track Safety Standards on the High Tonnage Loop at the Facility for Accelerated Service Testing in Pueblo, Colorado. The test section consists of 250 feet of independent dual block track and 250 feet of direct fixation slab track and the test train consists of locomotives and heavy freight cars with 39-ton axle loads. 170 million gross tons accumulated on the test section after three years of testing. During this time, maintenance of the slab track was not required to retain the Class 9 track geometry. This report summarizes the results of the field test which was cosponsored by the Federal Railroad Administration and the Portland Cement Association. The field test is part of the Cooperative Slab Track Research and Demonstration Program for Shared Freight and High Speed Passenger Service. The program was initiated to advance concrete slab track technology and to demonstrate the capability of concrete slab track to provide a low maintenance and safe track structure on track shared by high-speed trains and freight trains in the United States.
