New South Wales<br />

Airly Loop Junction (Wallerawang – Kandos<br />

line). The STOP Block located at 213.768km<br />

(adjacent to the Up Yard Limit Sign) was<br />

temporarily removed on 05/12/2017 to enable<br />

the entry of a works train proceeding towards<br />

Kandos. The STOP Block was reinstated after<br />

the passage of this train.<br />

North Shore line. Commencing 02/01/<strong>2018</strong>,<br />

new Auto signals were installed on the Up<br />

Shore line at 24.472km (SH15.20), 23.712km<br />

(SH14.76), 22.985km (SH14.30) and 20.265km<br />

(SH12.60). Existing Up Auto signal SH12.40<br />

(at 19.833km) received altered aspects. These<br />

alterations are designed to allow for headway<br />

improvements along this line.<br />

Ashfield Crossover points 502A/502B and<br />

503A/503B (Up end of station), which had been<br />

out of use since 14/11/2015, were removed<br />

from 06/11/2017.<br />

Blacktown New crossover points 352 at<br />

34.178km (which had previously been installed<br />

from 02/09/2017) were commissioned into use<br />

from 16/12/2017. These points allow Down<br />

trains to pass from the Down Suburban line<br />

to the Down Main line at the Up end of the<br />

station with a diverging speed of 70km/h<br />

allowed. Existing crossover points 320 (Down<br />

Suburban to Down Main, Down end of station<br />

at 35.964km) were removed. Shunt signal BN98<br />

was removed. Automatic signal M21.3 was<br />

converted to Controlled signal BN27M with<br />

aspect changes. Controlled signal BN89M was<br />

converted to Automatic signal M22.3, with the<br />

Shunt indication removed. Aspect changes<br />

were provided for signals BN29S, BN23S,<br />

BN47S, BN73S, BN91S, BN85UP and BN87UL.<br />

BN87 Indicator was altered to BN87 Co-Actor,<br />

receiving aspect changes as well.<br />

Boggabri Coal In conjunction with the<br />

commissioning of level crossing warning<br />

devices for the (private) Boggabri Coal<br />

Access Road from 10/10/2017, Up signal BC14<br />

(Boggabri Coal branch) was relocated from<br />

528.049km to 528.390km, and Up signal BC12<br />

(Maules Creek branch) was relocated from<br />

528.049km to 528.413km.<br />

Eveleigh Alterations are being made to the track<br />

arrangements at Eveleigh as part of the Inter-City<br />

Fleet Commissioning and Stabling Project.<br />

Commencing 09/12/2017, the Eastern Siding was<br />

extended in an Up direction by 26m. The existing<br />

buffer stop was relocated accordingly, and a new<br />

LED-type buffer stop light was provided. A new<br />

fixed train stop was installed 2.5m prior to the<br />

relocated buffer stop.<br />

Fassifern (North). Commencing 30/10/2017,<br />

crossover points 56A (Down Main) and 56B<br />

(Up Main) (facing crossover, allowing Up trains<br />

on the Up Main line to access the Down Main<br />

line thence the Newstan Colliery Sidings)<br />

were renewed and upgraded. Points 56B were<br />

relocated 5m in a Down direction.<br />

Ganmain (Junee – Griffith line). In conjunction<br />

with level crossing improvement works, three<br />

new Main Line Indicators were provided from<br />

16/01/<strong>2018</strong>. MLI “D” faces Down trains at<br />

538.067km; MLI “X” and “B” face Up trains<br />

at 538.099km and 539.090km respectively.<br />

The operation of these Main Line Indicators<br />

is interlocked with Frames D and B to prevent<br />

unnecessary operation of the level crossing<br />

warning devices.<br />

Glenfield (South Sydney Freight Line). New<br />

points 225B were installed at 39.879km on<br />

the Glenfield Passing Loop (Loop line) from<br />

02/12/2017. The points will form a connection<br />

into the future Moorebank Intermodal<br />

Terminal, and will remain locked and secured<br />

pending future commissioning.<br />

Gordon (North Shore line). Commencing<br />

04/11/2017, points 53A (catch, Local Platform<br />

Road) and 53B (Up Shore line) were renewed<br />

and upgraded. Points 53B were relocated 4m in<br />

an Up direction.<br />

Hornsby (Reference should also be made to<br />

<strong>Railway</strong> <strong>Digest</strong>, November 2017, page 47).<br />

Commencing 29/12/2017, the track connections<br />

between the Shore lines and the Main lines at<br />

the Down end of the station were removed.<br />

Double slip points 521A/522B were removed,<br />

with new single turnout 521A provided; the new<br />

points align with existing 521B points to form a<br />

simple trailing crossover between the Down and<br />

Up Main lines. Facing crossover points 523 (Up<br />

Main to Up Shore line) were booked out of use,<br />

locked and secured, with some track between<br />

these turnouts removed. Points 525A/catch<br />

525B were locked and secured in the normal<br />

position, allowing movements between the Up<br />

Shore line (platform 1) and the car sidings only,<br />

these were later removed. The low speed aspect<br />

on Down signal HY25 (Down Main, up end of<br />

station) was removed.<br />

Commissioning of the Hornsby Junction<br />

re-modelling works commenced on<br />

02/01/<strong>2018</strong>, and are planned to be brought<br />

into service from 16/01/<strong>2018</strong>. The junction<br />

area on the Down side of the station was<br />

re-configured to simplify the track layout. The<br />

Up Loop line was re-arranged on the Down<br />

side of the station (33.971km) towards the<br />

Bridge Road bridge at 34.669km to form the<br />

new Up Shore line. A new No. 1 Up Siding was<br />

formed between 33.971km and 34.418km,<br />

this now forms a Turnback track for the Shore<br />

lines, terminating at a friction buffer stop.<br />

The Inwards and Outwards Car Shed Roads<br />

were re-configured between 34.107km and<br />

34.459km and brought back into use, with<br />

routes available between platforms 1 – 4 and<br />

the Car Shed Roads. Frame B was brought back<br />

into use.<br />

The scissors crossover at the Up end of<br />

platforms 1 and 2 (points 515, 516, 517 and 518)<br />

was renewed on a new alignment, allowing<br />

the speed of trains diverging to be increased<br />
