Lecco-Colico-Sondrio-Chiavenna Railway.—In 1901 Ganz &Co., of Budapest, finished the electric equipment of what is usu-ally called the Valtellina Railway in the northern part of normal speed is 60 km (37 miles) per hour for passengertrains and 30 km for freight trains. The power station generates20,000 volts at 15 cycles per second, 12 transformers of 300 kweach, along the line about 10 km from each other, reduce this to3000 volts. There are two 8-mm trolley wires, the track servingas a third conductor. The rolling stock consists of passengermotor cars weighing 50 tons, and freight locomotives weighing. MODIFIED FORM OF CONTACT DEVICE USED IN TESTSAT GROSSLICHTERFELDE 40 tons each. Both are of the double-truck type, with one motorof 150 hp on each of the four driving axles. The motors aremounted direct on hollow shafts on the axles, driving the latterby means of a flexible coupling. For the passenger cars the so-called cascade connection is made use of, two of the motorsbeing connected to the 3000 volts directly, the other two to the 300volts induced in the rotors of the first two. Thus half-normal speed is obtained and a certain economy in starting. The freightlocomotives, however, use resistances only for starting contact device is of the roller type, two copper rollers 40 cmlong being separated by a piece of hard wood 12 cm long,saturated with parafin under at Grosslichterfelde.—.Still higher voltages were used by
