The final report on the pressure cell installation under the New York Central tracks near Trenton, Michigan was presented. The test installation was described. The pressure cells were removed from the ground and were found to be in good condition. Comparison of the pressure cell data for three years was given. The cells were recalibrated. Changes appeared to be uniform for all the cells. The dynamic calibration changed, but little or no change took place in the static calibrations. It is indicated that greater effects of impact and vibration are noted under steam locomotives. Vibratory and impact forces account for a considerable amount of the total pressure transmitted by rail traffic to the roadbed. Results indicate that this type of pressure cell when installed in plastic soils works well for dynamic loads, and can be used satisfactorily for this type of installation where the pressure cells are balanced before each set of readings. This type of cell is not applicable to the problem of measuring changes in dead-load pressures over long periods of time. Results of this investigation are limited in scope because the data obtained are only reliable for the one set of conditions of soil, moisture, track and loading at the particular location of the installation.
