The service test of the special 8-inch by 15-inch by 1-inch thick tie plates with 1 1/4 eccentricity on a 6 degree curve on the Iowa Division of the Illinois Central Railroad near Dubuque, Iowa is covered in this report. The construction consisted of four test sections of two track panels each, with 247-inch by 9-inch by 8-ft 6-inch sawed creosoted oak ties per panel. The last three sections have the 15-inch plates on the inner rail. Section one, used for controls has 13-inch plates under both rails. Initial readings of tie abrasion, gage of track, elevation and curvature of each panel were taken in October 1955. The penetration of the 13-inch plate under the outer rail is substantially greater than that of the 15-inch plate under the inner rail. Plates with lock spikes show the least abrasion. The cross level and curvature held reasonably during the life of the test. Pressure on the outer rail was much greater than anticipated. To obtain the desired results, consideration will be given to reversing the plates between the two rails to place the special plates in the outer rail.
