The Valtelina , occasional Valtellinabahn, Italian Ferrovia della Valtellina is a railway line through the Valtellina in Lombardy . The Valtellina Railway includes the sections from Colico to Lecco along the eastern shore of Lake Como , to Sondrio and to Chiavenna .

The routes were built according to the Baccarini law and initially operated by the Rete Adriatica (RA).

Networking

When the first two lines opened, the Valtellina Railway was an isolated network and itself only accessible by ship via Lake Como . With the construction of the Lecco – Colico line in 1894, it was connected to the Como – Lecco line, built in 1888, and thus with the remaining network of the Rete Adriatica and Italy. Today, regional trains Calolziocorte - Lecco - Colico - Sondrio and regional express trains Milan - Tirano operate on the route .

electrification

In 1902 the lines of the Veltlinbahn were electrified as the first main line in the world as well as the longest line at the time with high-voltage three-phase alternating current . The entire electrical equipment from the power station to the electric locomotives was provided by the Hungarian company Ganz . As electric locomotives, Ganz supplied both railcars ( RA 30 and 32 ) and locomotives ( RA 341–342 and RA 361–363 ).

In 1914 the electrification of the Valtellina Railway was continued as far as Monza , as was the case in 1932 on the 26 km long Sondrio - Tirano line operated by Ferrovia Alta Valtellina (FAV) . Otherwise, the electrical three-phase operation on the Veltlin-Bahn and the FAV remained an island network, although from 1914 to 1932 much more extensive networks in northern Italy were equipped with the same 3000-volt three-phase system and the corresponding motor vehicle fleet.

vehicles

The locomotive fleet of the Veltlinbahn was divided into ten railcars and nine electric locomotives of three different types.

The four-axle railcars had four directly coupled three-phase motors, two of which were designed as primary motors for 3000 volts and two as low-voltage motors. The latter are only used when all motors are connected in series . The power of a railcar was 386 kW (500 hp) and the weight of the electrical equipment was 21.5 tons.

The locomotives of the first delivery each had four directly coupled three-phase motors of 165 kW (225 hp) each, a total of 660 kW, which enabled a speed of 32 km / h . The weight of all electrical equipment was 26 tons each.

The locomotives were mainly used for freight traffic, passenger traffic was handled with the nine railcars.

The pantographs of the locomotives were a combination of roller systems and brackets . The roller system consisted of two copper cylinders, each 65 cm long and 8 cm in diameter, which rotated in insulated ball bearings on a wooden roller. The wooden roll is in turn carried by two support tubes on each side, with which it forms a bracket construction. This is raised or lowered against the power line with compressed air. The current from the line is fed from ring-shaped carbon contacts to the tubes carrying the roll.
