T1 line is not the extension of an existing network, nor it is the transformation of a working railway line into a streetcar line: even though it still uses the sedimentary grounds of the former “Ferrovia della Valle Seriana” railway station, T1 is a completely new line.

The track crosses the territories of Bergamo, Torre Boldone, Ranica, Alzano Lombardo, Nembro and Albino, over 12,5 km, and covers a population consisting of more than 220.000 people. The service commercial speed is 25 km/h, with a maximum speed of 70km/h. The line voltage is 750V, guaranteed by 10 electrical substations. 


Tramway rails is part of an integrated transportation system facilitating the exchanges between tram and buses within the urban area and the suburban area. On TEB tramway line, ATB and SAB Autoservizi travel documents are required.

At the main stops you can find free park and ride lots: BG Martinella (20 parking places), Torre Boldone (22 parking places), Ranica (52 parking places), Alzano centro (62 parking places), Alzano Sopra (68 parking places), Nembro Saletti (82 parking places), Pradalunga (57 parking places), Albino (155 parking places).

In partnership with the Administration of Bergamo, in 2009 we started the “Tram&Bike” project, which aims to develop an integration among public tramway system, cycle lanes network and bike-sharing service.
All along the line there are also several cycle and pedestrian lanes implemented by TEB in collaboration with the Provincial Administration and the interested Municipalities: from via Martinella (Bergamo) to via Colombera (Torre Boldone), from the “Ranica” stop to via Viandasso (Ranica), from the “Nembro Camozzi” stop to “Nembro Centro” and from the cemetery to via Crespi (Nembro), from the “Pradalunga” stop to the centre of the village. Recently, also the routes from “Bianzana” stop to “Borgo Palazzo” stop and to via David (Bergamo) have been opened.


The T1 line travels on a protected preferential route with 30 saturated crossings, set by intelligent traffic lights, which prevent car queues by only switching on when the tram passes, which occurs in a time range of 15 to 22 seconds.

There are three distinct braking systems and a driver monitoring device on the streetcars, in addition to 8 safety cameras. The latter are also located at stops, in the elevators and escalators, and in the storage area as well.

The tramcars travel with non-polluting electrical power supply, and are made with anti-vibration materials. 

The long stretches of grassy grounds (30.000 square meters of lawn, 35% of the entire railway network), the architectural elements and street furniture, cycle lanes and park and ride lots near the stops were designed to ensure minimal environmental impact.
Moreover, TEB is investing in research to minimize environmental impact: new systems to contain noise emission and new electronic elements to accumulate the power produced in braking and re-use it in acceleration.

TEB also collaborated with Unione Ciechi di Bergamo (Blind People Association in Bergamo) and with FAND, Federation of National Disabled People Associations, to ensure the access for everyone: in fact, on board you will find audio and visual alarms announcing the impending stop, the traffic lights of passing tram are equipped with audible signal and the two end of the line stations, as well as Borgo Palazzo stop, are equipped with tactile maps of the service.
People with hearing impairments are helped by on-board monitors indicating the next stop.


TEB has 14 Sirio tramways created by AnsaldoBreda, featuring Pininfarina design, colours and interiors designed by Mariuccia Mandelli aka Krizia, expressing their modernity in the top level comfort. 

Here are the main characteristics:

  • Low noise levels inside
  • Low floor on the entire inner surface
  • Large doors (6 for each side, with 1800 mm of useful space and - therefore - easy access for everyone)
  • No obstacles to accessing cars
  • Air conditioning system for passengers’ comfort (max 239, including 62 seats)

On-board features include an internal video surveillance system that, in addition to constituting a deterrent to vandalism or criminality, allows the driver to constantly monitor the car's condition.
