The latter machine also serves asa starter as will be described later.

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 a maxi-mum of 200 hp, measured
