SERVICE PERFORMANCE AND ECONOMICS OF 78-FT RAIL, SPECIFICATIONS FOR 78-FT RAIL

Tests and measurements made on two service installations of 78-ft rail were presented. The purpose of the tests on the Chicago & North-Western and the Pennsylvania Railroad was to determine if the presence of greater joint gaps on the 78-ft rail would create an increase in cost of maintaining the remaining joints, thereby reducing benefits due to the elimination of one half of the joints. Measurements show no outstanding difference between the 78-ft rail and the 39-ft rail at the Chicago and Northwestern site. At the Pennsylvania Railroad site measurements show pull-in of 78-ft rail to be almost identical to that of 39-ft rail. Joint gap measurements on the Illinois Central reveal that rail anchorage of 22 alternate ties boxed per 78-ft rail has given a more satisfactory rail gap uniformity than in earlier tests.
