It is also believed this samesystem of comparison can be applied to lighter conditions,such as are found on the average interurban road, and willgive means whereby the results on roads of this class can bestudied and compared with far greater satisfaction than withthe straight-mileage basis. It will also give a better basis. CAST-STEEL GEAR FOR GE 66 MOTOR, INTERBOROUGHRAPID TRANSIT COMPANY upon which to compare results with various classes of equip-ment on the same road. In arriving at the ton-mile unit, itwill, of course, be necessary to take the weight of the equip-ment without passenger load, and while this will not include the passenger-load factor, it will give a better basis for com-parison than the car-mile alone.
