A series of tests was conducted with 6-axle locomotives in heavy, coal drag service on Cranberry Grade to investigate the interaction of locomotive tractive power and track conditions. Particularly, the performance of 6-axle locomotives in this service was investigated to determine the relative merits of that design versus the 4-axle units previously used. Five major areas were found to be significant and completely interdependent: I. Locomotive wheel life with 6-axle units. II. Rail cleanliness affects locomotive adhesion. III. The condition of the track and the rail govern overall acceptability of 6-axle locomotives. IV. Operating practices covering the use of sand are related to increased wheel wear and increased track maintenance. V. Instrumented wheel tests: A. To determine to what extent and under what circumstances the wheel and rail wear attributable to 6-axle locomotives exceeds that of 4-axle units. B. To determine effect of track surface on locomotive riding qualities. C. To determine suitability of 6-axle locomotives.
