The railway motors arealso the same in the two equipments. They are wound forindependent excitation and are provided with artificial venti-lation and encased to keep out the dust and moisture. Theyare designed for 900 volts and a maximum speed of 1200r. p. m. The continuous output available for each motor is95 hp. Each, however, is capable of working up to
