Track Standards

This guidance note lists the drawings, including bowties, that are applicable to offtrack. It is applicable to those who: • specify asset requirements; • create or approve design; • undertake work to significantly amend or construct assets; or • carry out refurbishment or maintenance activities on...

5.1 This test method is part of an overall suite of related test methods that provide repeatable measures of robotic system mobility and remote operator proficiency. The variable diagonal rail obstacle challenges robotic system locomotion, suspension systems to maintain traction, rollover...

This specification deals with steel tie plates, low-carbon and high-carbon-hot-worked that are used in railroad tracks. The steel shall be manufactured by either basic-oxygen or electric-furnace processes and may be cast by a continuous process or in ingots. Both Grade 1 and Grade 2 tie...

1.1 This practice describes the differentiation, identification, and categorization criteria for tooling, both unique and more general in nature. The physical markings should allow for one or more of the following to be ascertained: part number, serial number, ownership, revision, or symbology, or...

This specification defines requirements for the data used in the tracking and traceability base-62 encoding system. It provides the format of the resultant code to characterize various components used in fuel gas piping systems. In this specification, the final output is a 16 digit...

This business process evaluates the complexity of construction works and the subsequent potential for track movement. It stipulates minimum monitoring requirements deemed necessary to foresee issues and confirm timely intervention can be actioned. This business process applies to any...

4.1 Significance-This guide provides additional guidance to preparers of environmental disclosures; these materials are needed to address changing audience needs, the increased regulatory and accounting complexity around environmental matters, and the emergence of a variety of long-term trends and...

5.1 This test method is part of an overall suite of related test methods that provide repeatable measures of robotic system mobility and remote operator proficiency. The parallel rails test challenges robotic system locomotion, operator control, effective camera positioning, chassis shape...

3.1 This guide can be used to obtain force versus deflection or midspan bending moment versus midspan curvature curves for stents and stent systems subjected to three-point bending conditions. Bending flexibility of a stent system may be a factor in its ability to track through the vascular...

This standard applies to revised inspection and maintenance regimes for plain line track system assessed using the Reliability Centred Maintenance process (NR/L2/MTC/10662) of the following assets on running lines: a) plain line flat bottom Continuously Welded Rail (CWR) - Regardless of PLPR...

This module of NR/L2/TRK/001 is applied where the track has been disturbed or a deficiency exists, which affects the Critical Rail Temperature. This might be as result of: a) deterioration in the track system; b) maintenance work, heavy maintenance or refurbishment works c) renewals...

The requirements of the modules in this standard apply to the inspection and maintenance of the following assets on running lines and sidings: a) plain line track; b) switches and crossings (S&C). The scope of the standard excludes Off track assets and closed lines. TMEs and SM[T]s...

This SIN applies to all track circuits where a ZKL3000RC T-COD has been installed prior to 01/02/2021. Purpose The purpose of this SIN is to determine the following for all track circuits where a ZKL3000RC T-COD has been fitted: 1. confirm a maintenance track circuit test has...

The standard applies to those who manage, plan, coordinate, control the use of and operate OTP on Network Rail managed infrastructure. This specification covers the following types of OTP: a) Demountable machine b) Road Rail Vehicle (RRV) c) Trailers d) Attachments with two or more rail wheels...

4.1 This guide presents some methodologies to predict the forces required to bring a disabled ship under control within the available limits of the waterway, taking into account local influences of wind and sea conditions. Presented are methodologies to determine the control forces that an escort...

This specification applies to all cross-track cables regardless of cable asset owner. This includes cables that may be managed by Station Infrastructure Managers or third parties that are required to cross Network Rail tracks. It applies to all renewal, enhancement and maintenance...

This document applies to site investigation scoping, site investigations, design, specifying track renewals and the installation of the track bed. This document applies to all ballasted track for renewals, enhancements and remodelling schemes. It does not apply to high speed...

This notice board applies to all staff involved in the management and testing of Wrong Side Failures associated with track circuits, including Route Control staff who deal with failure reports and those involved in the SINCs process. Purpose The purpose of this notice board is to provide a...
