SERVICE

By electric traction on the entire line, supplemented by a cable section (the only one of its kind).
Normal doublefacing tram cars coupled, on the Piazza Scorcola -  Vetta Scorcola section, to two buffer wagons attached to the ends of a traction cable running between the rails.
The terminus is located in the centre of town, in Piazza Oberdan, and the cable railway section begins just a few hundred meters away.
The tram takes you up from the city to the surrounding beautiful natural environment of the Carso plateau, 348 m above sea level.
The tourist also find this original form of transport (a cross between an extraurban tram and a cable railway) an unforgettable moment of their visit of Trieste.

CAR No. 1

The tram car bearing no. 411 is the oldest tram still running in Europe today.

When SOCIETA’ ANONIMA DELLE PICCOLE FERROVIE opened the service in question in 1902, this car was given the number 1, as the first of an initial fleet of 6 trams .

The mechanical parts were built by GRAZEN UNION FABRIK, which also constructed trams for SOCIETA’ DEL TRAMWAY ELETTRICO COMUNALE in Trieste, whilst the electrical components were provided by OSTERREICHISCHE UNION ELEKTRICITATS GESELLSCHAFT.

The outside was different from its present appearance, as the two driver's cabins had been designed without any protection at all for the driver, who thus found himself exposed to the elements.

In bad weather the driver therefore had to wear a large waterproof cape, with which he protected both himself and the controls.

Howewer, a few years later, in around 1908, windscreens were installed in the driver's cabins, while the chassis was slightly lengthened a little later still, in order to increase the original capacity of 44 passengers.

With the introduction of bogie raicars in around 1937 (still in use today), this car was withdrawn from service and converted into a support car, providing assistance in case of breakdown to a railcar (towing) and for repairs to the overhead cable (for which a special platform was added to the roof).

It was entirely restored by the local staff in 1992 and was given its commemorative run in the green livery adopted in the Twenties, exactly 90 years from the line's inauguration.

It is powered by two motors and carries 28 passengers, all seated.
