Permanent specific case CH-TSI INF-001: Infrastructure gauge: general The compatibility of OCF gauges with the international gauges under EN 15273-1:2013+A1:2016 is as follows:

—

Permanent specific case CH-TSI INF-002: Doors and steps in the open position. In Switzerland the provisions for the implementation of the Railways Ordinance DE-OCF, Article 47.2, point 7 must be complied with, in addition to the conditions according to EN 15273-2, Annex A, A3.14 ‘Specific rules for doors and steps in the open position’. In accordance to these provisions, the exceedance of the maximum vehicle construction gauge by the value wi, without exceeding 0,035 m, cannot be accepted below 0,6m above the rail. However, entrance doors that meet the conditions in leaflet UIC 560, points 1.1.4 to 1.1.4.3 are permitted.

—

Permanent specific case CH-TSI INF-007: Small radii (R < 250 m) related acceptance procedure. In order to allow using a line with a large number of radii < 250 m, an acceptance procedure of running characteristics of railway vehicles for this range of radii is necessary (see also R RTE 29001). The specifications for test and assessment are defined in regulation SBB R I-50127, based on EN 14363:2016+A2:2022 (2nd edition). Vehicles that do meet these requirements are not allowed to run on the defined lines with a large number of very small radii (see SBB R I-50127, point 1.2).

—

Permanent specific case CH-TSI INF-008: Presence of tight deflection curves and switches. The track layout in some station areas in Switzerland is technically difficult to use due to the presence of tight deflection curves (radii below 160 m) and short intermediate sections of track with correspondingly small distance between track centres. Therefore an acceptance procedure of assessment of vehicle behaviour in switches and crossings is necessary. EN 14363:2016+A2:2022 (2nd edition) does not specify any requirements for the assessment of vehicle behaviour in switches and crossings. The specifications for test and assessment of vehicle behaviour in switches and crossings applicable in Switzerland are defined in regulations R RTE 29001 and SBB R I-50007. Vehicles that do not meet the requirements of the SBB R I-50007 regulation are not allowed to run in regular service on the Swiss rail network.

—

Permanent specific case CH-TSI INF-010: Permissible sum of guiding forces of vehicles per wheelset. The permissible track displacement resistance of the infrastructure limits the maximum permissible sum of guiding forces of vehicles per wheelset. Due to the design of the track superstructure, a coefficient of α = k1 = 0,85 has to be used in Switzerland as a standard value for the calculation of the maximum permissible sum of guiding forces of a tested vehicle. A coefficient of α = k1 = 1,0 can only be applied in exceptional cases and requires special clarifications. Track tests for the running dynamic have to be carried out based on α = k1 = 0,85.

—

Permanent specific case CH-TSI INF-013: Vehicles tests for Swiss cant deficiencies to guarantee safe operation. The definition of permissible speed on the Swiss rail network bases on cant deficiencies of 130 mm (standard for freight trains) or 150 mm (standard for passenger trains) which apply without further assessment. It is therefore mandatory to test vehicles for such cant deficiencies to guarantee safe operation. Vehicles not tested for these cant deficiency levels are not allowed to run on the Swiss railway network.

—

Permanent specific case CH-TSI INF-014: Requirements with regard to minimal radius < 150 m. In Switzerland, the minimum radius set out for the free use of vehicles applies to:

These radii are based on the requirement in regulations R RTE 29001 and SBB R I-50007. They are based on the requirements of leaflet UIC 645. Vehicles not meeting these requirements must expect restrictions in the usability of shunting and connecting tracks (e.g. very important for automatic coupling systems).

—

Permanent specific case CH-TSI INF-017: Platforms – Design (height and distance from the track centre line) and track layout (radius and cant).

The specifications for the design of platforms, i.e. height, distance from the track centre line and track layout alongside the platform (minimum radius, maximum cant) are specified in type approval ZR44TZ2009-02-0004, issued by the OFT on 3 August 2021. Furthermore a platform height of 350 mm above the rail is permissible if a platform height of 550 mm (standard platform height in Switzerland)

Platforms that are built according to the above-mentioned type approval do respect the requirements of the lower part of the structure gauge according to point 4.2.3.1, paragraph (2) of TSI Infrastructure.

There are therefore no restrictions on the passage of interoperable vehicles.

The following national rules referred to in Article 6 of Decision No 2/2019 of the Joint Committee shall apply in Switzerland:

—

CH-TSI PRM-001 (version 2.0 of June 2021): Autonomous access to trains;

—

CH-TSI PRM-002 (June 2015): Infrastructure subsystem: Functional and technical specifications;

—

CH-TSI PRM-003 (June 2017): Infrastructure subsystem: Step position for vehicle access and egress.’

—

Permanent specific case CH-TSI ENE-001: pantograph loading gauge (TSI reference Article 4.2.10(1)).

For new, updated or renewed ‘energy’ subsystems on the Swiss interoperable network, the pantograph loading gauge must be specified in accordance with the implementing provisions of the Railways Ordinance of 15 December 1983 (DE-OCF; RS 742.141.11) version of 1 July 2024, re Article 18, Normal track, DE 18, figures, Figure 12, and re Article 18/47.2, DE 18.2/47.2, Reference contour, point 14, as follows:

—

Permanent specific case CH-STI LOC&PAS-004: Track displacement force (TSI reference Article 4.2.3.4)

The permissible track displacement resistance of the infrastructure limits the maximum permissible sum of guiding forces of vehicles per wheelset. Due to the design of the track superstructure, a coefficient of α = k1 = 0,85 has to be used in Switzerland as a standard value for the calculation of the maximum permissible sum of guiding forces of a tested vehicle. A coefficient of α = k1 = 1,0 can only be applied in exceptional cases and requires special clarifications. The dynamic type-approval tests must be carried out on the basis of the coefficient α = k1 = 0,85.

—

Permanent specific case CH-STI LOC&PAS-005: Cant deficiency (LOC&PAS TSI reference Article 4.2.3.4.2 and WAG TSI reference Article 4.2.3.5)

The definition of permissible speed on the Swiss rail network bases on cant deficiencies of 130 mm (standard for freight trains) or 150 mm (standard for passenger trains) which apply without further assessment. To ensure safe operation, it is therefore imperative that vehicles are examined in respect of such cant deficiencies. Vehicles which have not been examined in respect of such cant deficiencies cannot run on the Swiss rail network.

—

Permanent specific case CH-STI LOC&PAS-017: Infrastructure gauge: general (LOC&PAS TSI reference Article 4.2.3.1)

—

The compatibility of OCF gauges with the international gauges of EN 15273-1:2013 is as follows:

The infrastructure gauge (upper part) for all types of gauge (e.g. OCF O1, OCF O2, OCF O4) is calculated in accordance with EN 15273-1:2013, Annex C, C.2.1, Table C1 (Annex C, C.2.3, Table C4 respectively), subject to the reference kinematic profiles and the associated calculation rules. Use of the formulae under EN 15273-3:2013, Annex C, Tables C.2 and C.3 (for heights h > 3,250 m) is not permitted in Switzerland.

—

Permanent specific case CH-STI LOC&PAS-028: gauging, door area (LOC&PAS TSI reference Article 4.2.3.1)

In Switzerland, the requirements in accordance with DE-OCF, re Article 47, DE 47.2, point 7 must be complied with, in addition to the rules of EN 15273-2, Annex A, A.3.14 ‘Specific rules for doors and steps in the open position’. Accordingly, the construction gauge may not be exceeded for lateral entrance doors and for steps below 0,6 m above the running surface. However, entrance doors that meet the conditions in leaflet UIC 560, points 1.1.4 to 1.1.4.3 are permitted.
