Description ATP balises are of a fibreglass construction and are bolted directly to the sleepers or slab. A rectangular location ID plate is fixed to the top of the sleeper adjacent to each balise and has the same ID description as the circular balise ID plate. ATP balises may be either yellow or grey when new. Some balises are connected to a trackside junction box via a surface laid cable in an orange hose and these are known as 'controlled' balises. Some balises do not have a cable and these are known as 'fixed' balises. Typically a pair of balises (usually one 'fixed' and one 'controlled' balise) will be installed before every signal, but balises will also be found at other locations between signals. Reporting Requirements The ATP balises are a signalling critical asset and must not be disturbed without prior approval. It is critical that Signalling maintenance staff are made aware of any damaged, disturbed or removed balises, as this may cause operational delays to trains once the ATP system becomes operative on a line. The alignment of the balise relative to the track is important and any damage, including knocking a balise out-of-square must be reported.

BALISES FOR ATP – TRACK & CIVIL REQUIREMENTS
Background The TfNSW Automatic Train Protection (ATP) Project is progressively installing balises (transponders) in the four foot at locations across the network. These balises send signalling information to trains as they travel over them.
As at 13 May 2013, balises have been installed between Wyong and Asquith, and in the Blacktown area with some remaining at test sites in the Blue Mountains between Penrith and Mount Victoria.
Description ATP balises are of a fibreglass construction and are bolted directly to the sleepers or slab. A rectangular location ID plate is fixed to the top of the sleeper adjacent to each balise and has the same ID description as the circular balise ID plate. ATP balises may be either yellow or grey when new.
Some balises are connected to a trackside junction box via a surface laid cable in an orange hose and these are known as 'controlled' balises. Some balises do not have a cable and these are known as 'fixed' balises.
Typically a pair of balises (usually one 'fixed' and one 'controlled' balise) will be installed before every signal, but balises will also be found at other locations between signals.
Reporting Requirements The ATP balises are a signalling critical asset and must not be disturbed without prior approval.
It is critical that Signalling maintenance staff are made aware of any damaged, disturbed or removed balises, as this may cause operational delays to trains once the ATP system becomes operative on a line.
The alignment of the balise relative to the track is important and any damage, including knocking a balise out-of-square must be reported. In particular, care must be taken not to damage the cable or cable connection point at a 'controlled' balise or the adjacent trackside junction box.

If there is any damage to balises it should be reported via the Infrastructure Operations Centre (IOC) on (02) 9379 5555.
Trackwork Precautions Prior to commencement of ballast ploughing, re-sleepering, ballast cleaning or re-railing and any other activity where there is a high risk of damage, ATP balises and their cables will need to be removed from the track to a safe place and re-fitted, after the works have concluded by authorised persons.
Any track work which may impact on balises, balise cables or their junction boxes should be first discussed with the Signal Engineer, to determine work strategies.
Do not:
• drag a rail in the four foot, over or past a balise fitted on the track.
• run over a balise with vehicle wheels.
• step on a balise cable plug.
When storing rails in the four foot, do not:
• store more than two rails side-by-side.
• encroach within 1m of a balise
• allow the ends of a pair of stored rails to overlap by more than 10m, as the additional metal mass may be detected by the on-board ATP system resulting in an alarm and subsequent train braking application.
As part of the Possession Planning process, track activities need to be scheduled well in advance in order to ensure appropriate signalling and track resources are available.

Balise Types
1) Example of two 'fixed' Balises on open track between signals
2) Example of a pair of Balises ('controlled' and 'fixed') before a signal. Note the cable connected to the 'controlled' balise in the foreground.
3) Example of a pair of Balises between guard rails. Note the cable connected to the 'controlled' balise in the background.
