Particularities: Tilting technology "SIBI"

The three-part diesel multiple unit ATR (AutoTReno) 365 was built by CAF for fast traffic on the Italian Mediterranean island of Sardinia . Its four-part variant was given the designation ATR 465 . The six three-car trains have been in use since 2014, the two four-car trains came to Sardinia in 2019.

technology

The multiple unit consists of two motorized end cars and a likewise powered intermediate car (train composition Mc-M-Mc), all of which have the active tilting technology "SIBI", which can tilt the car bodies by up to 6 °. After the technical acceptance, the first train was relocated to Tuscany to carry out test drives for Trenitalia on the LFI- operated branch line Arezzo – Sinalunga.

The train has, among other things, air conditioning, barrier-free toilets and boarding aids, anti-graffiti paintwork, surveillance cameras and a passenger information and fire alarm and fire extinguishing system.

procurement

The multiple units were ordered by the Sardinia region in 2010. The order consists of five trains plus an option for another three of the same type. The contract, including maintenance, spare parts and training, has a value of 57 million euros over the next five years. The Italian state took over 54 million and the region 3 million. Including maintenance and servicing, each train costs 9.2 million euros. A hall in Cagliari was expanded for maintenance.

Delivery and service

ATR 365 003 (Cagliari)

Delivery started in 2013. The trains will be entrusted to Trenitalia, which will use them to fulfill the transport contract with the Sardinia region. In 2012 it comprised 169 trains per day with a passenger volume of 4.4 million travelers. The ATR 365 connect the south of the island ( Cagliari ) with the northeast ( Olbia ) over a 277 km long route and the north-western part of the island ( Sassari ), this route is a total of 253 km . Both routes follow the same route to the fork at Ozieri . In addition, a relation between Cagliari and Carbonia is used, which connects the south-east and south-west of the island. The new trains are expected to cover the north-south route faster than the current two hours, twenty minutes (six stops) and two hours, ten minutes (two stops), respectively.

Tilting technology SIBI

CAF's own tilting technology SIBI ( acronym for S istema I nteligente de B asculación I ntegra ) is characterized by the fact that the route with all its characteristics is stored in the on-board computer, similar to a navigation device in the car sector. This means that it is necessary to travel a route with a SIBI tilting train before the scheduled deployment in order to be able to obtain the relevant route data. GPS signals and sensors in the bogies, which enable the distance covered to be calculated, are evaluated to determine the exact position . Balises between the tracks and acceleration sensors on the train, which other systems such as B. GNT exclusively support, were only used during the testing phase in the 1990s.

Due to the stored route data, the train starts tilting even before the start of the curve; an abrupt change does not take place - as with well-optimized gyroscope-based tilting systems. Similar to the Neicontrol-e system from Adtranz (today Bombardier), the inclination is carried out electromechanically via a spindle drive which is attached to the bogie. The mechanics for this are supplied by Moog from Böblingen .

In the future, the European Galileo system is to be used instead of GPS . First, because it offers greater accuracy; second, because GPS has proven to be unreliable in wartime.

SIBI knows three operating modes:

  • Deactivated: The train operates in the speed class like any normal train (Spanish speed class "A", corresponds to a lateral acceleration: 1.0 m / s 2 )
  • Without previously stored route data: The train leans in curves, but not fully (Spanish speed class "B", corresponds to an uncompensated lateral acceleration of 1.2 m / s 2 )
  • With route data stored in advance: The train begins the tilting movement before the start of a curve (Spanish speed class "D", corresponds to an uncompensated lateral acceleration of 1.8 m / s 2 )

Other multiple units that use SIBI which are series 594 and 598 of the RENFE .
