relief from shocks. The whole gear system works easily and makes very little noise. The switches for controlling the current are on both platforms the car running in either direction. The coils of the fieldmagnets of the motors are divided into a number of sections and the switch makes different arrangements of these coils putting them all in series when the current is least or in parallel when the current is greatest or using different combinations for intermediate powers. The cars are under perfect control: they start easily and can be backed instantly in case of emergency. Brakes are used both for Christian Louboutin Outlet the wheels and on the track the ordinary wheelbrake not being sufficient for some of the steep grades that occur. Power is supplied from a central station in about the middle of the line. There are six dynamos givingvolts andamperes each. The line was opened for traffic with ten cars running. They were crowded with passengers during the day; and the heavy travel together with the inexperience Christian Louboutin Outlet of the drivers was a severe test for the system.
