The FRA-sponsored Kansas Test Track, an 8000-ft field laboratory composed of eight segments utilizing concrete ties and continuous longitudinal concrete beams and slabs and ballast stabilized by an elastomeric polymer, has been retired. Early in 1977 FRA will present a final report telling how the stretch adjacent to Santa Fe's mainline at Eldorado, Ks., performed and failed to perform. The goal had been to understand the improvement in track stability, performance and maintenance requirements resulting from incremental increases in stiffness. When AT&SF revenue freight trains first traversed the track at low speed, track fasteners on the beams failed. After months of repairs, trouble developed again after the line was reopened. Beams again developed problems but mud pumping around them and under the stabilized ballast indicated that the entire subgrade was failing. Some of the track components will be reused at Pueblo, Colo.
