Measurements were made on a test installation for the study of rail anchorage for continuous welded rail. The purpose was to obtain data on (1) the effect of train movements on rail anchorage forces (static before and after) and (2) the relation between rail anchorage force and tie movement. This installation was on tangent track with 115 RE continuous welded rail. All weight bars were loosened for the first train to obtain zero readings and a 100-lb force was applied to eastbound anchors (anchors to restrain easterly rail movement). All westbound anchors had the bolts adjusted to just be in contact. The joint gap and rail temperature were measured periodically. Also, the rail position lengthwise of the track was measured at each of 7 test locations. These measurements were then repeated after each of four trains had passed to show the change that had been effected by the train passage. Tests were also made to determine the resistance or force required to move the ties in the ballast. Specific results from the various tests are presented in several tables. Truck housing dynamic recording equipment was driven to the test site and information was recorded under all trains during a two-day period. The recording equipment consisted of 12-carrier amplifiers and a direct writing oscillograph. Ten channels recorded the longitudinal rail forces exerted through rail anchors to the weigh bars on the ties. The remaining two channels, connected to extensometers, were used to measure the longitudinal movement of the rail and tie with respect to the reference pipe.
