MOTORS AND ROLLING STOCK The standard train on this line weighs 40 metric tons each other on the rack sections and in parallel on the othersections. The two motors which are used on the rack sec-tions only are always operated in parallel. As all motorsare of the same size and have about half the output,at the same speed., when running in series to that pos-. Monthey-Champery Railway—First Rack Section and accommodates 70 passengers. In choosing the motorequipment it was figured that for trains of this weight atractive pull of 6000 kg (13,200 lb.) would be required onthe maximum rack grade of 13 per cent and 2300 kg (5060lb.) on the maximum grade of 5 per cent where the rack sessed when running in parallel, the total output on therack sections is about three times that on the adhesionsections, a condition which corresponds to the grade con-ditions. The following table shows the tractive efforts ofthe motors under different conditions of speed:
