((1)) Depending on the assessment method, the overhead contact line shall achieve the values of dynamic performance and contact wire uplift (at the design speed) set out in Table 4.2.12.
((2)) S0 is the calculated, simulated or measured uplift of the contact wire at a steady arm, generated in normal operating conditions with one or more pantographs with the upper limit of Fm at the maximum line speed. When the uplift of the steady arm is physically limited due to the overhead contact line design, it is permissible for the necessary space to be reduced to 1,5S0 (refer to EN 50119:2009, clause 5.10.2).
((3)) Maximum force (Fmax) is usually within the range of Fm plus three standard deviations σmax; higher values may occur at particular locations and are given in EN 50119:2009, table 4, clause 5.2.5.2. For rigid components such as section insulators in overhead contact line systems, the contact force can increase up to a maximum of 350 N.

Power consumption of the train (traction, auxiliaries and no-load current of the transformer) shall be brought to zero before entering the phase separation section. Adequate means (except for the short separation section) shall be provided to allow a train that is stopped within the phase separation section to be restarted.
((2)) The overall length D of neutral sections is defined in EN 50367:2012, clause 4. For the calculation of D clearances in accordance to EN 50119:2009, clause 5.1.3 and an uplift of S0 shall be taken into account.
 4.2.15.2. Lines with speed v ≥ 250 km/h 

Two types of designs of phase separation sections may be adopted, either:


((a)) a phase separation design where all the pantographs of the longest TSI compliant trains are within the neutral section. The overall length of the neutral section shall be at least 402 m.
For detailed requirements see EN 50367:2012, Annex A.1.2, or
((b)) a shorter phase separation with three insulated overlaps as shown in EN 50367:2012, Annex A.1.4. The overall length of the neutral section is less than 142 m including clearances and tolerances.
 4.2.15.3. Lines with speed v < 250 km/h 

The design of separation sections shall normally adopt solutions as described in EN 50367:2012, Annex A.1. Where an alternative solution is proposed, it shall be demonstrated that the alternative is at least as reliable.
 4.2.16. System separation sections 
 4.2.16.1. General 


((1)) The design of system separation sections shall ensure that trains can move from one power supply system to an adjacent different power supply system without bridging the two systems. There are two methods for traversing system separation sections:

((a)) with pantograph raised and touching the contact wire;
((b)) with pantograph lowered and not touching the contact wire.
((2)) The neighbouring Infrastructure Managers shall agree either (a) or (b) according to the prevailing circumstances.
((3)) The overall length D of neutral sections is defined in EN 50367:2012, clause 4. For the calculation of D clearances in accordance to EN 50119:2009, clause 5.1.3 and an uplift of S0 shall be taken into account.
 4.2.16.2. Pantographs raised 


((1)) Power consumption of the train (traction, auxiliaries and no-load current of the transformer) shall be brought to zero before entering the system separation section.
((2)) If system separation sections are traversed with pantographs raised to the contact wire, their functional design is specified as follows:

((a)) the geometry of different elements of the overhead contact line shall prevent pantographs short-circuiting or bridging both power systems;
((b)) provision shall be made in the energy subsystem to avoid bridging of both adjacent power supply systems should the opening of the on-board circuit breaker(s) fail;
((c)) variation in contact wire height along the entire separation section shall fulfil requirements set in EN 50119:2009, clause 5.10.3.
 4.2.16.3. Pantographs lowered 


((1)) This option shall be chosen if the conditions of operation with pantographs raised cannot be met.

Appendix D
Specification of the pantograph gauge
D.1 SPECIFICATION OF THE MECHANICAL KINEMATIC PANTOGRAPH GAUGE 
 D.1.1 General 
 D.1.1.1 Space to be cleared for electrified lines 

In the case of lines electrified by an overhead contact line, an additional space should be cleared:


— to accommodate the OCL equipment,
— to allow the free passage of the pantograph.

This Appendix deals with the free passage of the pantograph (pantograph gauge). The electrical clearance is considered by the Infrastructure Manager.
 D.1.1.2 Particularities 

The pantograph gauge differs in some aspects from the obstacle gauge:


— 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 pantograph gauge is only met if the mechanical and electrical gauges are complied with simultaneously:


— 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.
 D.1.2 Specification of the mechanical kinematic pantograph gauge 
 D.1.2.1 Specification of the width of the mechanical gauge 
 D.1.2.1.1 Scope 

The width of the pantograph gauge is mainly specified by the length and displacements of the pantograph under consideration. Beyond specific phenomena, phenomena similar to those of the obstacle gauge are found in the transverse displacements.

The pantograph gauge shall be considered at the following heights:


— The upper verification height h′o
— The lower verification height h′u

Between those two heights, it can be considered that gauge width varies in a linear way.

The various parameters are shown in figure D.2.
 D.1.2.1.2 Calculation methodology 

The pantograph gauge width shall be specified by the sum of the parameters defined below. In the case of a line run by various pantographs, the maximum width should be considered.

For the lower verification point with h = h′u:
b′ui∕a,mec=bw+epu+S′i/a+qs′i/a+∑jmax
For the upper verification point with h = h′o:
b′oi∕a,mec=bw+epo+S′i/a+qs′i/a+∑jmax
For any intermediate height h, width is specified by means of an interpolation:
b′h,mec=b′u,mec+h−h′uh′o−h′u×b′o,mec−b′u,mec D.1.2.1.3 Half-length bw of the pantograph bow 

The half-length bw of the pantograph bow depends on the type of pantograph used. The pantograph profile(s) to be considered are defined in LOC&PAS TSI, point 4.2.8.2.9.2.
 D.1.2.1.4 Pantograph sway ep 

The sway mainly depends on the following phenomena:


— 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′.
 D.1.2.1.5 Additional overthrows 

The pantograph gauge has a specific additional overthrows. In case of standard track gauge the following formula applies:

For other track gauges the national rules apply.
 D.1.2.1.6 Quasi-static effect 

Since the pantograph is installed on the roof, the quasi-static effect plays an important role in the calculation of the pantograph gauge. That effect is calculated from the specific flexibility s0′, reference cant D′0 and reference cant deficiency I′0:
qs′i=S′0LD−D′0>0h−h′c0qs′a=S′0LI−I′0>0h−h′c0 D.1.2.1.7 Allowances 

According to gauge definition, the following phenomena should be considered:


— 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 sum of the abovementioned allowances is covered by Σj.
 D.1.2.2 Specification of the height of the mechanical gauge 

Gauge height shall be specified on the basis of the static height hcc, of the contact wire at the local point under consideration. The following parameters should be considered:


— 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.

The height of the mechanical gauge is given by the following formula:
heff=hcc+fs+fws+fwa D.1.3 Reference parameters 

Parameters for the kinematic mechanical pantograph gauge and for Specification of the maximum lateral deviation of the contact wire shall be as follows:


— 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
 D.1.4 Calculation of maximum lateral deviation of contact wire 

The maximum lateral deviation of the contact wire shall be calculated by taking into consideration the total movement of the pantograph with respect to the nominal track position and the conducting range (or working length, for pantographs without horns made from a conducting material) as follows:
dl=bw,c+bw−b′h,mec
bw,c — defined in points 4.2.8.2.9.1 and 4.2.8.2.9.2 of LOC&PAS TSI

D.2 SPECIFICATION OF THE STATIC PANTOGRAPH GAUGE (TRACK GAUGE SYSTEM 1 520 mm) 

This is applicable for Member States accepting the pantograph profile in accordance with LOC&PAS TSI point 4.2.8.2.9.2.3.

The pantograph gauge shall conform to Figure D.3 and Table D.1.
