In this case these assessments shall remain valid in the new application. If it is not possible to demonstrate that the solution is positively proven in the past, the procedure for ICs placed on the EU market after publication of this TSI applies.

(c) existing certified ICs OCL.

(a) New lines with speed greater than 250 km/h shall accommodate both pantographs as specified in the LOC & PAS TSI points 4.2.8.2.9.2.1 (1 600 mm) and 4.2.8.2.9.2.2 (1 950 mm).

(b) Renewed or upgraded lines with speed equal or greater than 250 km/h shall accommodate at least a pantograph with the head geometry specified in the LOC & PAS TSI point 4.2.8.2.9.2.1 (1 600 mm).

(c) Other cases: the OCL shall be designed for use by at least one of the pantographs with the head geometry specified in the LOC & PAS TSI points 4.2.8.2.9.2.1 (1 600 mm) or 4.2.8.2.9.2.2 (1 950 mm).

(a) Where Article 20(2) of Directive 2008/57/EC applies, Member States shall decide which requirements of the TSI shall apply, taking into account the implementation plan.

(b) Where Article 20(2) of Directive 2008/57/EC does not apply, compliance with this TSI is recommended. Where compliance is not possible, the contracting entity informs the Member State of the reason thereof.

(c) When a Member State requires a new authorisation for placing into service, the Contracting Entity shall define the practical measures and different phases of the project which are necessary to achieve the required levels of performance. These project phases may include transition periods for placing equipment into service with reduced levels of performance.

(d) An existing subsystem may allow the circulation of TSI-compliant vehicles whilst meeting the essential requirements of Directive 2008/57/EC. The procedure to be used for the demonstration of the level of compliance with the basic parameters of the TSI shall be in accordance with Commission Recommendation 2014/881/EU ( 5 ).

(1) It is possible to gradually modify all or part of the OCL and/or the power supply system — element by element — over an extended period of time to achieve compliance with this TSI.

(2) However, compliance of the entire subsystem can only be declared when all elements are compliant with the TSI over a complete section of route.

(3) The process of upgrading/renewal should take into consideration the need of maintaining compatibility with the existing energy subsystem and other subsystems. For a project including elements not being TSI compliant, the procedures for the assessment of conformity and EC verification to be applied should be agreed with the Member State.

(1) The specific cases, as listed in point 7.4.2, describe special provisions that are needed and authorised on particular networks of each Member State.

(2) These specific cases are classified as:

— Nimes to Port Bou,

— Toulouse to Narbonne,

— A comparison with a reference where the power supply solution has been used for a similar or more demanding train schedule. The reference shall have a similar or larger:

—

— A rough estimation of Umean useful for simple cases resulting in an increased additional capacity for future traffic demands.

— Simulations shall be carried out on a zone which represents a significant part of a line or a part of the network, such as the relevant feeding section(s) in the network for the object to be designed and assessed.

— For simulation of U mean useful (train) and U mean useful (zone) only trains that are part of the simulation during a relevant time, such as the time needed to go through a complete feeding section, have to be considered.

— to accommodate the OCL equipment,

— to allow the free passage of the pantograph.

— The pantograph is (partly) live and, for this reason, an electrical clearance is to be complied with, according to the nature of the obstacle (insulated or not),

— The presence of insulating horns should be taken into account, where necessary. Therefore a double reference contour has to be defined to take account of the mechanical and electrical interference simultaneously,

— In collecting condition, the pantograph is in permanent contact with the contact wire and, for this reason, its height is variable. So is the height of the pantograph gauge.

— The free passage reference profile includes the pantograph collector head length and the pantograph sway ep, which applies up to the reference cant or cant deficiency,

— Live and insulated obstacles shall remain outside the mechanical gauge,

— Non insulated obstacles (earthed or at a potential different from the OCL) shall remain outside the mechanical and electrical gauges.

— The upper verification height h′o

— The lower verification height h′u

— Play q + w in the axle boxes and between bogie and body.

— The amount of body inclination taken into account by the vehicle (depending on the specific flexibility s0′, the reference cant D′0 and the reference cant deficiency I′0 ).

— The mounting tolerance of the pantograph on the roof.

— The transverse flexibility of the mounting device on the roof.

— The height under consideration h′.

— Loading dissymmetry;

— The transverse displacement of the track between two successive maintenance actions;

— The cant variation occurring between two successive maintenance actions;

— Oscillations generated by track unevenness.

— The raising fs of the contact wire generated by the pantograph contact force. The value of fs depends on the OCL type and so shall be specified by the Infrastructure Manager in accordance with point 4.2.12.

— The raising of the pantograph head due to the pantograph head skew generated by the staggered contact point and the wear of the collector strip fws + fwa . The permissible value of fws is shown in LOC & PAS TSI and fwa depends on maintenance requirements.

— l — according to track gauge

— s′o = 0,225

— h′co = 0,5 m

— I′0 = 0,066 m and D′0 = 0,066 m

— h′o = 6,500 m and h′u = 5,000 m
