terand one Bristol recording ammeter. Two panels are used tocontrol the incoming lines and the current to the five trans-former controlling panels. The third remaining panel hasmounted on it one 12,000-volt oil switch, which is used to con-trol the lines to the North Albany sub-station. The high-tension wires are brought into the northeast cornerof the station and down to the main switchboard. The high-tension transformer feeders are carried from the switchboardaround the north and west walls of the station, being properlyspaced and mounted upon suitable insulators, each consecu-tive three wires running to their respective group of trans- 302 STREET RAILWAY JOURNAL.

From the low-tension side of each group of trans-formers three heavy feeders are carried down outside of trans-former tanks and into the cable duct beneath the platform, thenrunning into a cross duct, which leads into a cable duct under-neath the low-tension switchboard; they are then carried up

From the direct-current end of the rotaries heavy cables arecarried down through the cable duct across to the direct-currentrotary controlling panels, and from there the current is con-veyed over solid copper bus-bars on the back of the board to thevarious direct-current feeder panels. From the feeder panelsthe current is conveyed to the trolley feeders over heavy cables. In the roof of this station are installed five 36-in. Globeventilators. These are not only used to maintain proper circu-lation of air through the main building, but also force acirculation of air through the cable ducts beneath the floor,thus providing against
