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 />
