MEASUREMENT OF TIE PLATE LOADS

This report covers the measurement of the tie plate loads in tangent track under both steam and diesel power. Two dynamometer tie plates were operated in tests involving measurement of rail creepage forces that are transmitted from the rail to the ties by rail anchors. Tests were made in two series of runs. Consecutive ties were uniformly supported in condition A. Adjustment of the support to permit the dynamometer tie to swing in the second series of runs was termed condition B. Several records were taken under 6-wheel and 4-wheel truck diesel and medium weight locomotives. Condition B with swinging ties resulted in an average increase in tie plate loads of 4,000 for the steam locomotives, as compared with 5,0000 with diesel locomotives. The individual tie plate loads measured under the diesels were more uniform in magnitude than for the medium weight locomotives. The steam locomotives produced higher individual tie plate loads than the diesels.
