Checking this entire thread, the following useful tabulation could not be found. Inland Rail (IR) uses these succinct abbreviations (such as "T2A Tottenham to Albury) extensively and RailPagers are recommended to use the same. The table below would have straighter columns if a common width font can be used, most fonts being of non-standard widths for each character.
The 13 sections of the IR are:
Since the site of the Melbourne Freight Hub has yet to be determined, the starting point of T2A may not necessary be Tottenham.
Changing to Font Courier New gets a neater table.
T2A Tottenham-Albury (1) (305km)
A2I Albury-Illabo (2) (185km)
I2S Illabo-Stockingbal (3) (37km)
S2P Stockingbal-Parkes (4) (99km)
P2N Parkes-Narromine (5) (104km)
N2N Narromine-Narrabri (6) (300km)
N2NS Narrabri-North Star (7) (186km)
NS2B North Star-NSW/QLD Border (8) (39km)
B2G NSW/QLD Border-Gowrie (9) (216km) (DG = Dual Gauge)
G2H Gowrie-Helidon (10) (28km) (DG) (6000m Tunnel)
H2C Helidon-Calvert (11) (47km) (DG) ( 805m Tunnel)
C2K Calvert-Kagaru (12) (53km) (DG) (1100m Tunnel)
K2ARB Kagaru-Acacia & Bromelton (13) (49km) (DG)
In the Tottenham-Albury (T2A) and Albury-Illabo (A2I) sections 10 of the existing crossing loops are less than the 1800m standard. It is also the case that some loops in Queensland (B2G), G2H, H2C, C2K and K2ARB sections are 2200m long which has 400m to spend on other characteristis. For example 250m might be spend on simultaneous arrivals, and 150m on slow down zones.
SA require an overlap (aka Safety Margin) past the Departure (Starting) signals, which give some protection for Signal Passed At Stop (SPAD). The slow down zone means that the rear of the 1800m train clears the single section at say 15km/h rather than say
There is a problem with the flashing yellow (FY) signals in QLD (Queensland) compared to NSW (New South Wales)
* QLD FY means signal has no overlap, so pass that signal carefully. (More restrictive)
* NSW FY means (1) next signal at Caution (yellow); (2) next signal is Junction Clear (Yellow or Green) (Less Restrictive)
This serious contradiction can be resolved if all QLD Loop arrival (Home) signals do have overlaps, which could be the case if the QLD loops are 2200m. Remember that the QLD lines are dual gauge, where by the QLD and NSW drivers are involved.
It is not clear if signals in QLD will follow QLD or NSW practice, especially on the dual gauge sections. Double Yellows also have contradictory meanings in QLD compared to NSW; fortunately the these aspects are several hundred km apart. Similarly contradictions exist between Green over Red in NSW compared to VIC.
