1. INTRODUCTION 1.1 Context

Transport for New South Wales have entered into a Public Private Partnership with ALTRAC Light Rail to operate and maintain the SLR.

ALTRAC will be accredited as Rail Infrastructure Manager and Rail Transport Operator by the Office of the National Rail Safety Regulator (ONRSR) for Full Operations of the Sydney Light Rail.

As required, ALTRAC will develop a Rail Safety Interface Agreement (RSIA) with nominated Road Managers in order to manage Safety Risks, in compliance with the Rail Safety National Law (RSNL).

ALTRAC have contracted Transdev as Operation and Maintenance (O&M) Contractor to deliver the obligations to provide safe and reliable Light Rail Operations, for which Transdev have implemented Safe working rules and procedures that are currently in place for Inner West Light Rail Operations.

For the purpose of the CSELR, Transdev will develop and expand Safe working rules and procedures to encompass both lines of the Sydney Light Rail network (IWLR and CSELR).

During the Operation and Maintenance Phase, O&M and External Parties will work together to facilitate access into the Permanent Light Rail Corridor and/or the Danger Zone to enable External Parties to undertake routine repair and maintenance of assets, as well as emergency works.

1.2 Safety risks in the vicinity of the Light Rail

As with any Light Rail system, the Sydney Light Rail (SLR) poses specific risks, which must be assessed when considering working in and around the PLRC and/or the Danger Zone:

• Light Rail Vehicles (LRVs) are rail vehicles carrying up to 466 passengers:

o LRVs are a potential risk to External Parties working near or around the corridor, as LRVs cannot steer to avoid obstacles in their path.

o External Parties are a potential risk to LRV movements, as emergency braking on LRVs can cause injuries to passengers.

• Overhead Catenary Wires:

o Carry 750V DC electrical current at all times which can cause electrocution.

o Are a mechanical structure that can collapse if damaged by adjacent works.

• Pedestrian and Road Traffic arrangements on and around the PLRC can be affected by any works occurring close to the PLRC, and can increase risks for Light Rail Operations, as well as for Pedestrian and Road Traffic.

1.3 Purpose of the document

This document has been developed to summarise rules and guidelines required to ensure:

• External Party assets can be accessed and maintained safely with respect to Rail Safety risks.

• External Parties when working in and around the PLRC, are aware:

o That Rail Safety risks could be affecting their activities.


SLR-TDS-MI0-000-GUI-000010 6/8

o That their activities could affect Safety of Light Rail Operations.

• External Parties have an understanding that a Permit System has been introduced by Transdev in order to manage safe working in and around the PLRC.

• Clear communication channels and permit processes have been established between Transdev and External Parties.

2. LIGHT RAIL ACCESS PERMITS 2.1 Access Permits Principles

An Access Permit is required prior to any works that:

• Take place within the Danger Zone and/or,

• Are likely to introduce risks to the Light Rail Operations and/or,

• Are likely to be at risk from Light Rail Operations [i.e. Moving Trams, Traction power or pedestrian/road traffic].

Access Permits are authorised by the Light Rail Operator Sydney or its authorised delegate and are issued by the Light Rail Operator Operations Control Centre.

The workflow in Appendix 1 describes the steps to follow to request an Access Permit from the Operator. Following assessment, the Light Rail Operator will determine if an Access Permit is required or not.

2.2 Access Permits Requirements

A diagram showing Danger Zone is included in Appendix 2 of this guide.

2.2.1 GENERAL REQUIREMENTS

Access Permits are required where any works of the following nature are planned near the Sydney Light Rail System:

• Within the Danger Zone (refer Appendix 2), that is defined by an offset of:

o 1.25 metres from the outside running rail

o 3.00 metres from overhead power supply lines and their supporting wires and fixings.

• Where works are likely to divert pedestrians or road traffic into the Danger Zone

• Where works will generate vibrations, settlement dust or smoke that could affect the Light Rail Corridor and/or equipment.

• When erecting hoarding or scaffolding adjacent to the Light Rail Corridor.

• When using cranes or other equipment at any distance over the tramway.

• When excavating within the Danger Zone on a public road.

• When installing any permanent structure or equipment the Danger Zone.

• When placing of plant, material or spoil within the Danger Zone.

• When excavating beneath the track and within the Danger Zone.

• When falling onto overhead line cables;

• When causing vibration that may affect the tramway such as demolition or foundation construction works. Any such activities that are outside the danger zone must also follow the directions of the relevant authority;

• When any trenchless methods of tunnelling beneath the track slab; or

• When the movement of any high loads under the OCS or abnormal loads over the track slab


SLR-TDS-MI0-000-GUI-000010 7/8

Where there’s any doubt as to whether permission is required from the Light Rail Operator, it is recommended to contact Transdev for guidance.

2.2.2 DIAL BEFORE YOU DIG

If External Party works involve excavating in and around the Light Rail Infrastructure, Dial before you Dig processes have to be followed.

Dial Before You Dig will ensure utility / underground services information maintained by the Light Rail Operator of the Sydney Light Rail, will be accessible to the External Party.

Dial Before You Dig will route External Parties’ enquiries to the Transdev website.

3. NATURE OF THE WORKS 3.1 Planned Works

3.1.1 PREVENTATIVE AND CORRECTIVE ROUTINE WORKS

Preventative routine works are scheduled in advance by the external party with reference to Technical Maintenance Plans. In addition, regular corrective work may be carried out under an annual permit with a pre-agreed methodology.

Note:-

• If the proposed work is likely to create a risk to Light Rail operations, then the SWMS must detail mitigations to prevent or minimise this risk.

• If the light rail systems create a risk to the work to be carried out or personnel carrying out the work, then the SWMS must detail the control to mitigate this risks

Access Permit application request and/or renewal will have to be submitted:

• Service Authority & Occupation Authority: 3 weeks in advance of works

• Possession and Isolation Authority: 6 weeks in advance of works

• Before annual expiry.

3.2 Unplanned Work

3.2.1 URGENT WORKS

Urgent work is:

• a situation which does not represent an immediate risk to persons, goods and assets,

• a restoration of supply of water, gas, electricity, telecommunications or any other form of public utilities service.

Following an assessment being undertaken, mitigation of risks affecting persons and assets can be established in urgent situations.

Examples:

• Works required on a water main to remediate a water leakage,

• Consecutive lights failure on a section of the alignment.

Access Permit application request for Urgent works must be directed to the OCC in the first instance, and will be actioned as quickly as possible by the Light Rail Operator.


SLR-TDS-MI0-000-GUI-000010 8/8

3.2.2 EMERGENCY WORKS

Emergency works are defined as works that become necessary as a result of a serious unexpected and/or dangerous situation that must be remediated without delay to safeguard life, plant and/or property.

Examples:

• Flooding on street section which requires drainage cleaning on track immediately,

• Tree trimming of a branch required following major storm event,

• Overhead wire fallen onto the corridor. Access Permit application request for Emergency works must be directed to the OCC in the first instance, and will be actioned immediately by the Light Rail Operator (taking into account the light rail operational requirements).

4. PERMIT PROCESS – ASSESSING SAFETY 4.1 Access Permit Request – Inputs

In order to allow the Operator to assess risks for issuing an Access Permit, the External party must provide the following documents:

• SWMS: brief but detailed description of what the External party needs to do and how the External party plans to do it, including what machines / tools / vehicles / plant / equipment will be used.

• Location: include marked-up photos and/or a marked-up drawings / maps highlighting the area of work and the minimum distance of any work area to the nearest track.

• Risk Assessment: brief but clear statement of how the External party will mitigate the following risks (as applicable):

� LRV movements / operations. � Overhead power lines (750 volts DC) and associated support systems (no machines /

tools / vehicles near 3.0 meters of the overhead power lines or its support system, unless otherwise agreed & documented).

� Pedestrians Management Plan and Traffic Management Plan (to manage the risk of directing staff / pedestrians / traffic onto the Light Rail as a consequence of the works).

Access Permit request must be done in accordance with the documentation listed in the table below.

4.2.2 PERMIT TYPES

4.2.2.1 Annual Permit

For planned preventative or curative works that have been pre-assessed between the External Party and the Light Rail Operator, on the basis of all required documentation as per the appropriate risk assessments, the Light Rail Operator may issue an Annual permit.

The Annual Permit will include all safety requirements, and will enable the External Party to perform works in accordance with the Access Permit content.

Prior to initiating the works, some annual permits will require the external Party to notify the Light Rail Operator.

4.2.2.2 One off Permit

For all works requiring a Possession with Isolation, a one-off permit will be issued by the Light Rail Operator.

For all works not covered by an Annual Permit, the Light Rail Operator will issue a one-off permit and define the conditions under which the works can be carried out.

4.3 Induction and Training

The Operator will provide an induction (Light Rail General Safety Induction – LRGSI) for External Parties intending to carry out works in and around the Light Rail Corridor.

The relevant party may provide this training, with the prior agreement and approval of the Operator, to their own staff, via their own personnel, who will have attended the Operator’s training.

4.4 Access Permit System

Current IWLR Operations requires External Parties to apply for Access Permits by contacting the Light Rail Operator Interface Manager of the Light Rail OCC.

While preparing for SLR Full Operations, the Light Rail Operator is currently developing an online processing system, and will consult with key stakeholders while scoping and developing the system.

5. SAFETY 5.1 General safety

The LRVs are driven under line of sight rules, ie at a speed at which they can be stopped within the distance that the driver can see. They are, except for their inability to steer around obstacles, no different in this respect to normal road vehicles. LRVs can travel at speeds of up to 80kph; however it should be noted that their braking distances are generally two to three times greater than those of other road vehicles. The signals on the light railway are those provided at road junctions in addition to the normal traffic light signals where the tracks pass through a public road junction. Compliance with this code of


SLR-TDS-MI0-000-GUI-000010 10/8

engineering practice does not relieve any party of any of its duties of care to the public and/or its personnel/contractors or any of its responsibilities under statute.

5.2 The Electric Traction System - danger and precautions

The OCS comprises contact wires suspended over the track, from which electric current is collected by the LRV via pantograph. The contact wires may be supported by means of poles, masts, or building fixings. The methods of support vary with the application, but include cross span wires or ropes, bracket arms, and cantilevers. For on-street sections the minimum height of the contact wire above the rail will be between 5.5 metres and 6 metres, unless appropriate signs indicate that the wire is lower than this (for example, under low bridges). For segregated off-street sections, the minimum height of the contact wire will be 5.2 metres, unless appropriate signs indicate that the wire height is lower. The OCS is charged with electricity at up to 925 volts direct current. The OCS, attachments, and some supporting wires have no protective covering, so are potentially dangerous to approach. THE OCS MUST BE CONSIDERED TO BE LIVE AT ALL TIMES.

The only time that this will not be the case is if the authorised person has given specific written confirmation that an isolation has been carried out, ie the OCS between nominated limits has been isolated from all live conductors, proven dead, earthed, and declared safe through the issue of the appropriate documentation.

APS comprises of a steel plate in the centre of the running track which is energised when covered by an LRV, the LRV collects power from the plate by means of a pick up shoe. This system is used to allow the LRV to run under power without the need for an overhead wire.

5.3 Electrical safety guidance within the ETS

No works shall be allowed to take place anywhere within the ETS unless a works access permit and the appropriate documentation indicating limits of isolation, is obtained from the Operator.

Plant may be driven across the light railway at public road crossings or at other locations with the prior agreement of the Light Rail Operator providing that all telescopic arms, booms, buckets, platforms and jibs on the plant are in position for normal public road driving, and all tipping and demountable cab mechanisms are in their lowest positions.

The vehicles must comply with the RMS height and axel load requirements.

At locations remote from normal public road crossings where it is agreed that plant is to cross under the OCS, precautions as laid down by the Safe Work Australia must be taken, in consultation with the Light Rail Operator.

These must fully comply with SWA recommendations concerning barriers and goalposts, which must be constructed to the dimensions specified by the Light Rail Operator at the time of the consultation. The Light Rail Operator may vary these dimensions from one crossing location to another, depending on its operational needs.

When in operation, no mechanical excavator, lifting, or platform plant, or water jet shall be allowed to approach the ETS danger zone unless the plant is being driven in accordance with the above access guidelines (see appendix 1 for diagram of said danger zone). Ladders for use within the ETS danger zone must be of all-timber construction, or of an approved insulating alternative, in which metal reinforcing is not permitted. If ladders of metal or mixed construction are to be used outside the ETS danger zone, consideration will be given to ensure that their use minimises risk. It is not permitted to direct water towards any part of the OCS.

Any scaffolding erected close to the OCS shall be earthed, or otherwise electrically protected, after consultation with the Light Rail Operator. Where fixed scaffolding installations exist incorporating ladders or other means of access, measures must be taken to prevent unauthorised access whilst the site is unmanned. Any personnel working near the tramway, whether within or outside the ETS, must take special care when carrying out the following type of works:


SLR-TDS-MI0-000-GUI-000010 11/8

• oiling, washing, painting, repairing or carrying out works on any type of lighting standards, signals, buildings and other structures;

• carrying or using paint, water or other liquids in positions where they are likely to be thrown, to fall or to be projected onto the OCS;

• Carrying or using materials such as rope, wire, metal or conductive measuring tapes, pipes, rods, poles, ladders or brooms, mops or similar articles; or

• Tree felling or pruning.

• Using tower cranes or other lifting equipment.

• Erecting scaffolding or hoarding.

Where these items are of such length that if not carried horizontally there would be a possibility of them coming into contact with or close to the OCS, they must be carried horizontally, not raised above shoulder height, and by two or more persons if necessary. If any problems in complying with these guideline procedures arise, the External Party must consult the Light Rail Operator, so that suitable mutually agreed arrangements can be made to take all reasonable precautions to avoid danger.

6. 5. VIBRATION AND SETTLEMENT 6.1 VIBRATION

Without diminishing the relevant party’s responsibility to prevent any damage arising from works, the maximum allowable vibration levels as measured by peak particle velocity (PPV) at any point on the light railway shall be as follows:

LEVEL 1 LEVEL 2 LEVEL 3

PPV above 50Hz 10 mms-1 12 mms-1 15 mms-1

PPV 50 Hz and below 10 mms-1 10 mms-1 10 mms-1

For all works the following procedure shall apply (all references to vibration readings or results shall be deemed to mean vibration measurements obtained from the monitoring instrumentation):

6.1.1 VIBRATION READINGS BELOW TRIGGER LEVEL 1

As long as measured vibrations are below level 1, works can continue as applied

6.1.2 VIBRATION READINGS BETWEEN TRIGGER LEVELS 1 AND 2

In the case when measured vibration results exceed level 1, the relevant party shall initiate a review of his techniques and propose alterations to his methods including measures for reduction of vibration. These measures shall consider the works techniques, the geological conditions and other relevant factors. Any such measures shall be tested, applied and carefully monitored by the relevant party.

6.1.3 VIBRATION READINGS BETWEEN TRIGGER LEVELS 2 AND 3

In the event of vibration readings exceeding trigger level 2 or when damage to the light railway has been suspected, the associated works shall cease and the relevant party shall initiate a review of his techniques. The relevant party shall submit details of his proposed modifications to the works to ensure that vibrations do not exceed trigger level 1. The modifications shall be identified in a document submitted to the Light Rail Operator. Works shall not recommence without the consent of the Light Rail Operator.

6.1.4 VIBRATION READINGS ABOVE TRIGGER LEVEL 3

In the event of vibration readings exceeding level 3 in a discrete event, the procedure as described in (5.4.4) shall apply.


SLR-TDS-MI0-000-GUI-000010 12/8

In addition, the general application of works procedures and assessment methods shall be in accordance with BS 7385 (1993): Evaluation and measurement for vibration in buildings Part 2: Guide to damage levels from ground-borne vibration or equivelant

6.2 SETTLEMENT

During works such as demolition, excavation, piling, deep construction, at, near or adjacent the light railway, a full settlement monitoring regime is required to ensure the track rail alignment remains within tolerance.

This regime, its operation and submittal of monitoring results to Light Rail Operator, shall be provided by the External Party at their expense and issued to the Light Rail Operator for approval.

A set of trigger values will be formally notified to the External Party, as well as the full technical aspects of the monitoring regime, as a constraint to ensure the safety of the light railway is not compromised by settlement or twist of the track.

The Light Rail Operator will require a formal agreement to implement the monitoring regime on the following basis, as a minimum:

The External Party shall agree to ensure that they consult with the Light Rail Operator and obtain Light Rail Operator approval in regard to the necessary monitoring and mitigation measures to be taken at all locations where the light railway is within the zone of influence of the proposed works. The extent of the zone of influence for the works shall be agreed with the Light Rail Operator.

The External Party shall provide adequate notice to the Light Rail Operator of the works before they start and in particular give at least eight weeks’ notice prior to the placing of track monitoring equipment or any structural condition monitoring equipment on the light railway.

Take baseline readings for a period of at least two weeks prior to works likely to have an impact on the light railway (eg piling or adjacent excavation). During the two week period monitoring readings must be taken on a daily basis.

When the works are taking place in the zone of influence, take the monitoring readings on a continuous basis. When the works have passed beyond the zone of influence, take the monitoring readings on a daily basis for a further two week period or until ground settlements cease, whichever is the latter.

Ensure that all monitoring readings taken are received by the Light Rail Operator no later than 9.00am the day following that which they were taken, or sooner if requested.

The Light Rail Operator turn, shall agree not to withhold or delay unreasonably any approval sought.

Trigger values for settlement (subject to change prior to formal issue by the Light Rail Operator):

AMBER 4mm per 20m maintain Light rail operations with reduced speed

RED 6mm per 20m halt operations until corrective measures in place
