(28) in point 6.2.4.2, points (1) and (2) are replaced by the following: ‘(1) A design review for assessment of the distance between track centres shall be done using the results of calculations made by the Infrastructure Manager or the contracting entity on the basis of the specification referenced in Appendix T, Index [3].
The nominal distance between track centres shall be checked at the line layout where distances are given in parallel to the horizontal plane.
The limit installation distance between track centres shall be checked with the radius and relevant cant.
(2) After assembly before putting into service, distance between track centres shall be verified at critical locations where the limit installation distance between track centres as defined in accordance with the specification referenced in Appendix T, Index [3] is approached by less than 50 mm.’; (29) in point 6.2.4.4, the following point (3) is added: ‘(3) At assembly before putting into service, for the review of the minimum horizontal curve the measurement values provided by the applicant or infrastructure manager shall be assessed.
Rules for acceptance of works defined by the infrastructure manager shall be taken into account.’; (30) point 6.2.4.6 is replaced by the following: ‘6.2.4.6.
Assessment of design values for equivalent conicity Assessment of design values for equivalent conicity shall be done using the results of calculations made by the infrastructure manager or the contracting entity on the basis of the specification referenced in Appendix T, Index [5].’; (31) point 6.2.4.10 is replaced by the following: ‘6.2.4.10.
Assessment procedure of existing structures (1)
The assessment of existing structures against the requirements of points 4.2.7.4(3)(b) and (c) shall be done by one of the following methods: (a) A check that the values of EN line categories, in combination with the allowed speed published, or intended to be published, for the lines containing the structures, are in line with the requirements of Appendix E; (b) A check that the values of EN line categories, in combination with the allowed speed specified for the bridges or for the design, or alternative requirements specified with LM71 and factor alpha (α) for P1 and P2, are in line with the requirements of Appendix E; (c) A check that the traffic loads specified for the structures or for the design against the minimum requirements of points 4.2.7.1.1, 4.2.7.1.2 and 4.2.7.2.
When reviewing the value of factor alpha (α) in accordance with points 4.2.7.1.1 and 4.2.7.2, it is only necessary to check that the value of factor alpha (α) is in line with the value of factor alpha (α) set out in Table 11; (d) where the requirement for an existing bridge is specified by reference to the design load model HSLM in Appendix E, the assessment of the existing bridge shall be done by either of the following methods: — checking the specification of the design of the existing bridge, — checking the specification of the dynamic appraisal, — checking the published load carrying capacity of the existing bridge in the register of infrastructure (RINF) for the parameter 1.1.1.1.2.4.2 (Compliance of structures with the High Speed Load Model (HSLM)); (e) where the requirement for an existing bridge is specified by reference to alternative dynamic loading requirements (Appendix E note 8), the assessment of the existing bridge shall be done by checking the specification of the dynamic appraisal for these alternative loading requirements against the requirements in Appendix E note 8.
