3.3 NETWORK DESCRIPTION

Connecting facilities with the foreign networks

The relations between foreign network Infrastructure Managers, with respect to border traffic services, are regulated by international agreements entered into by the IM themselves, the provisions of which are referred to in the access contracts concluded with the Railway Undertakings (see Section 2 – Annex 1b). Regarding any service requests by Railway Undertakings operating in the connecting facilities with foreign networks, reference should be made to the application procedures and timelines set out in sections 5 and 6 below. The connecting stations between the domestic and foreign networks are:  for the French border: the stations of Ventimiglia and Modane;  for the Swiss border : the stations of Domodossola, Domo II, Luino, Chiasso and the Arcisate-Stabio line;  for the Austrian border the stations of Brennero, Tarvisio Boscoverde and S. Candido;  for the Slovenian border the stations of Villa Opicina and Nova Gorica. Following is the contact information for the infrastructure managers of the networks bordering with the Italian network:

3.3 NETWORK DESCRIPTION

The rail network structure shown in the ePIR portal is broken down into basic elements consisting of arcs developing between the two ends represented by Network facilities or stations and service locations (junctions, communication facilities). It is possible, thanks to the selected representation, to investigate in detail the characteristics of the basic section and/or end facility.

3.3.1 Geographic Identification

In the ePIR portal, the railway lines and facilities are reported in accurate geo referenced detail. The following elements are shown as reference points on the maps:  Regional capital cities  Main locations  Other locations  Engineering locations

3.3.1.1 Type of track

The ePIR portal shows the information relating to the length of the line sections broken down by type of track (single/double track).

3.3.1.2 Track gauge

The gauge of the national rail infrastructure lines if 1435 mm.

3.3.1.3 Stations

The distance between the stations can be found in the ePIR portal. The name and geographical location of the border stations can be found in the ePIR portal.

3.3.2 Line characteristics

3.3.2.1 Loading gauge

Line coding is shown in the ePIR portal. In the case of oversize cargo (overall dimensions exceed limits of the loading gauge), reference must be made to paragraph 2.6.

3.3.2.2 Axle mass limits

Regarding the axle mass category, the line characteristics of the lines highlights presence of special limitations relating to axle-loads above the accepted limit; these limitations can be found in the document called “Caratteristiche tecnico-funzionali della Infrastruttura ferroviaria nazionale gestita da RFI” (Engineering and functional characteristics of the railway infrastructure managed by RFI) and will be communicated during the planning phase on request of the RUs concerned.

The values corresponding to classifications shown in the map are as follows:

Table 3.3 – Mass for line category

Category Mass per axle Mass per current metre

D4 C3 B2 A 22.5 t 20.0 t 18.0 t 16.0 t

8.0 t/m 7.2 t/m 6.4 t/m 5.0 t/m In the case of cargo above these weight limits, reference should be made to paragraph 2.6.

3.3.2.3 Line gradient

The maximum line gradient (expressed in “thousandths”), for both directions, can be found in the ePIR portal.

It is possible to mention in greater detail and place the rail lines and facilities within the context of the other infrastructure (for example, the thematic open street map makes it possible to superimpose the road and rail infrastructure).

3.3.2.4 Line speed

The line speed, in its minimum and maximum values for each permitted speed class in the line section; the speed classes, and relevant permitted trains, are given in the Line Files/Timetable Files shown in the ePIR portal.

3.3.2.5 Maximum length of trains

The line module – representing the maximum length that can be used by the passenger and freight trains on the line (locomotive(s) plus hauled stock) – is shown in the ePIR portal.

3.3.2.6 Power supply system

The power supply systems available in the Manager’s network are: a) ET (Electrical Traction) by direct current at 3000 V on conventional lines; b) ET (Electrical Traction) by alternate current at 25,000 V on HS/HC lines; c) DT (Diesel Traction) on non-electrified lines.

3.3.2.7 Lines where trains with a mass exceeding 1600 tonnes are allowed (updated December 2019)

The ePIR portal indicates the lines where trains with a mass exceeding 1600 t are allowed without the need for specific authorisation for excess mass transport. In any case, circulation is subject to compliance with the specific interface regulations issued by the IM. The grid of the lines can be reviewed, in response to the requests that will be made to the IM by the Applicants, and updated, following the necessary technical feasibility checks, according to the timing for reviewing the reference interface standard.

3.3.3 Traffic Control and Communication Systems

3.3.3.1 Signalling systems

The line equipment, including the possibility of relaying signals to traction vehicles, can be found in the ePIR portal.

3.3.3.2 Traffic control systems

The control system adopted on the infrastructure is indicated in the ePIR portal. BAB means Blocco Automatico Banalizzato, automatic block of two-way working lines, BA means Blocco Automatico, automatic block, BCA means Blocco Conta Assi, axle-counter block, BEM means Blocco Elettrico Manuale, hand-operated electric block, ERTMS means European Rail Traffic Management System.

3.3.3.3 Communication systems

The ground-to-train communication system, called GSM-Railway, was introduced on 25 October 2004. Since then the national Infrastructure Manager is directly responsible for the mobile communications services for railway operations, among which are emergency calls, group calls and the handling of priority calls.

3.3.3.4 Train operation control and protection systems (updated in December 2019)

Train operation control systems

The line operating system of the infrastructure is indicated in the ePIR portal. The symbols used are: DC means Dirigente Centrale (Central Traffic Controller), CTC means Controllo Centralizzato del Traffico (Centralized Traffic Control), where the Dirigente Centrale Operativo operates, DL means Dirigenza locale (Local Traffic Controller), DU means Dirigente Unico (Single Track Line Traffic Controller); where “Others” is written, reference should be made to the service publications relating to the line.
