Railway applications - Track - Acceptance of works - Part 1: Works on ballasted track - Plain line, switches and crossings

This European Standard specifies the minimum technical requirements and the tolerances for the acceptance of works on ballasted track situated on plain line and on switches and crossings and rail expansion devices, as part of the track, for 1 435 mm and wider track gauge railways, concerning construction of new track, track renewal and track maintenance. More particularly, this standard gives the requirements for the documentation of work parameters, for the tolerances for relative track geometry and absolute track position and for the acceptance procedures.
This standard does not deal with contractual and legal aspects and it does not cover either works related to reprofiling the railhead nor the associated measurements, except for some measurements related to safety, since these works are covered by other parts of EN 13231 series.
Related works, e.g. platform reconstruction, formation, drainage, level crossings are not covered by this standard.

The customer may request additional documented measurements or checks if contractually agreed. The customer may also restrict the choice of measuring devices if contractually agreed. Relative track geometry shall be measured by a track recording vehicle or by a track construction and maintenance machine fitted with measuring equipment, both in accordance with series EN 13848. If the measuring equipment fails, or is not available, corresponding light weight or manual devices measurements shall be taken and documented. Other use of light weight or manual devices measurements shall be in accordance with series EN 13848. If track works affect track geometry, measurement of relative track geometry according to series EN 13848 shall be performed before allowing commercial trains to run. For the purpose of acceptance, every section and switch and crossing shall be inspected by the experts as nominated by the customer and the contractor. SIST EN 13231-1:2013

EN 13231-1:2013 (E) 8 The contract shall define who should perform the measurements and how they shall be documented. 4.4 Relative track geometry 4.4.1 Parameters 4.4.1.1 General

Measurements as defined in EN 13848-1. 4.4.1.2 Track gauge and cross level Measurement:  by track recording vehicles according to the requirements of EN 13848-2; or  by track construction and maintenance machines according to the requirements of EN 13848-3; or  by track measuring trolleys or manually operated devices, according to the requirements of EN 13848-4, with a minimum of 10 measurements on successive sleepers, every 100 m. 4.4.1.3 Longitudinal level and alignment Measurements for longitudinal level should preferably be undertaken on both rails. Measurement for alignment should be undertaken on both rails on straight track and shall be undertaken on the outer rail in curves:  by track recording vehicles according to the requirements of EN 13848-2; or  by track construction and maintenance machines according to the requirements of EN 13848-3; or  by track measuring trolleys or manually operated devices, according to the requirements of

EN 13848-4. 4.4.1.4 Twist Measurement:  by track recording vehicles according to the requirements of EN 13848-2; or  by track construction and maintenance machines according to the requirements of EN 13848-3; or  by track measuring trolleys or manually operated devices, according to the requirements of

EN 13848-4, measurements should be performed at least every 3 m. 4.4.2 Tolerances Accepted track shall comply with the tolerances shown in Tables 1 and 2.

The tolerances in Tables 1 and 2 are for loaded track measurements, which are recommended. For unloaded track measurements, the customer shall specify the tolerances for the relative track geometry parameters, which should be stricter. All measurements shall be sampled at constant distance based intervals not larger than 0,5 m. SIST EN 13231-1:2013

EN 13231-1:2013 (E) 9 For track construction and maintenance machines that move non-continuously and measure track geometry whilst working, the sampling interval may be extended up to 1,5 m. For track gauge, values shown in Tables 1 and 2 apply to both isolated defects of track gauge and mean track gauge as defined in EN 13848-1. The track gauge between any two adjacent sleepers shall not vary by more than 1 mm, unless otherwise specified by the customer (only applicable for hand measurements). For measurements made by track recording vehicles, track construction and maintenance machines or track measuring trolleys, the track gauge shall not vary by more than 3 mm per 1,5 m, unless otherwise specified by the customer. Concerning the longitudinal level and alignment for plain line and switches and crossings: a) the customer shall decide if 10 m chord measurement results or D1, D2 or D3 results according to EN 13848-1 should be used; b) the analysis method shall be "mean-to-peak"; Recording vehicles and track construction and maintenance machines delivered prior to the issue of this standard may use the analysis method "peak-to-peak". The values of the tolerances should be set by the customer. For special analysis of track geometry during and after tamping and stabilising work as on short sections with difficult track geometry and on switches and crossings, track construction and maintenance machines may use the analysis method "peak-to-peak". The values of the tolerances should be set by the customer. c) for chord measurements the following applies: 1) At chord measurement results, the sliding mean for each point shall be taken in a length not longer than 40 m considering a symmetric interval. 2) For alignment, the corridor as defined by the mean and the tolerances shall include the design value; if not, the defect shall be taken between the design value and the peak. 3) Chord measurements by recording vehicles or track construction and maintenance machines shall be made by an asymmetrical chord with a ratio of 40 % to 60 %, which should be 10 m long; for measurements by trolleys or manually operated devices a symmetrical chord with 10 m (in curves) and 20 m (in straight tracks) may be allowed. 4) Recording vehicles and track construction and maintenance machines delivered prior to the issue of this standard may use a symmetrical chord as well. 5) For measurements made by a chord system with base lengths other than 10 m, the results shall be converted to 10 m asymmetrical chord (40 % to 60 %) results. The twist base length shall normally be 3 m, and the analysis method shall be "zero-to-peak". In transition curves with design twist, the tolerances shall be considered from the design twist, but not from the zero line, without exceeding the intervention limit values of EN 13848-5. Where a twist base length other than 3 m is used, the customer shall specify the acceptance tolerances. For tracks built with used materials, including switches and crossings, the tolerances for the parameters shall be specified by the customer.

In case of partial renewal, the customer shall specify if Table 1 or Table 2 or a combination of both is applicable.SIST EN 13231-1:2013

Class AP 1 tolerances may be reduced in order to allow for restricted structure gauges.

4.5.3 Compliance measurements When requirements and tolerances for the deviation from design track position are applied, following items shall be specified by the customer: a) Compliance measurements shall refer to defined survey point in the track. The survey point defines the absolute track position. The survey point and spacing of control measurements shall be defined by the customer. b) The external reference system, normally a network of geodetic reference points, and geodetic measurements for verification of the absolute track position shall be specified by the customer. Guidelines for specification of requirements for geodetic measurements are given in Annex A. The absolute track position shall be measured from geodetic reference points, e.g: c) total station measurements; d) levelling: 1) satellite measurements; 2) measurement tape or equivalent. 4.6 Other parameters and verifications for plain line and switches and crossings 4.6.1 General Requirements and tolerances in 4.6 apply to new track, renewal and maintenance work. 4.6.2 Sleeper spacing Permissible deviation from the designed sleeper spacing shall be ± 20 mm (except at welds or other justifiable cases) and shall be checked by sampling. Checking shall be made at least every 200 m. SIST EN 13231-1:2013

Permissible deviation from squareness of the sleepers shall be ± 10 mm. 4.6.5 Voiding of the sleepers and bearers This sub-clause is only applicable on request from the customer. The quality of the tamping shall be checked by sampling 10 % of the sleepers and bearers.

All sleepers and bearers shall be fully supported under the rails (not voided). When tamping machines are not used, 5 % voided sleepers are permitted, but the following shall apply:  no more than two adjacent voided sleepers shall be permitted;
