Table Top Crossing Loop - Removal

 
  Campaspe 2 Locomotive Driver

Hello,

I have heard a rumor that the disused crossing loop at Table Top (between Albury and Gerogery on the Main South) may be (or maybe it already has been) removed. Could someone in the local area confirm the status of the loop, i.e. if it is still there or not.

Table Top Loop has been out of use since 14 April 2010 after a number of components had been removed from the points at each end of the loop. It was no longer being used by this stage on account of:

  • The loop being too short for the trains then being run on the Melbourne - Sydney corridor (It was around 900 metres long versus freight train lengths of 1500 to 1800 metres).
  • The opening of the Passing Lane at Gerogery on 9 May 2008 reducing the length of the single line section between Gerogery and Albury, thereby reducing the need for a loop in this section (The Gerogery Crossing Loop was extended at the Albury end to form the Passing Lane. I think the original Gerogery loop was around the 900 metre mark, whereas the Passing lane is around seven kilometres long or around 6 kilometres longer than the original Gerogery Loop).

Table Top Loop was originally commissioned in February 1984 as part of the program to introduce Centralised Traffic Control (CTC) between Junee and Albury.

Thanks

Regards

It was still there yesterday morning but lengths of rail have been going missing from the loop for a while. The loop at Ettamogah is being installed during a shutdown in September maybe Table Top will my pulled up then?

Thanks Bevan and Fatty for the feedback on Table Top.

Fatty, how is work going on the Ettamogah siding extension?

Kind Regards

The points are installed at each end, the formation is complete and foundations for signals are in place. The sleepers, rail and ballast are on site ready to go.

For a diagram of Table top and Ettamogah see: http://www.sa-trackandsignal.net/Pdf%20files/ARTC/AR252.pdf. Table Top is shown as being out of use. The new points are shown, but as the diagram is not to scale it is not possible to say how far apart they are.


ETT and TT are only 2.3km apart (centre to centre) and nearly touch.

This diagram show new mainline turnouts that may well convert Ettamogah into a 1800m crossing loop, as well as having the hardstand and paper mill sidings.

These siding are currently accessed by those high technology ground frames E & D.

The new points for Ettamogah and the old Table Top points are 100 metres or so apart.

With the Tynan road level crossing in between.

It should be noted that the Hume highway is only about 50m from this level crossing, so that it is important that no b-doubles stop for the the level crossing in front and block the highway in the rear.

The most common points numbers are:
* 51 at the Sydney .end of the loop; (most likely)
* 55 at the Country end of the loop.  (fairly likely)

I thought that Tynan Road wasn't allowed to be used by B-Doubles anyway?

For info, approx. distances as follows (pre Ettamogah completion)

Between Albury and Ettamogah - 12.3km
Ettamogah length - 1.0 (frame to frame)
Between Ettamogah and Table Top - 1.5km
Table Top length - 1.1km (points to points)
Between Table Top and Gerogery PL - 6.6km
Gerogery length - 7km (points to points)

Approx length Albury loop (SYD end) to Gerogery PL (ABX end) is 22km.  There is some discussion in a previous thread about the merits or not of duplication all the way to Gerogery from Albury.

I have discussed with a few people over the years, the option, and most have agreed, that the track needs to be duplicated from the 303.500km peg on the Victorian side to through to the 623.269km peg on the N.S.W. side, which is 22.68km worth of double duplication that would need doing. The biggest hurdle that has been raised is crossing the Murray, as the existing bridge would need to be replaced, as it currently does meet the safety margin.

In the case of the Ettamogah siding, measure between the catchpoints,

The all-important crossing loop length is not measured between the points at the end of the loop (1.1km) but rather between the VIC: departure (NSW:starting) signals at either end of the loop (0.900km).

By the way, the Albury loop at 1671m is shorter than 1800m. Can it be lengthened easily? Are higher speed trunouts, say 80km/h, possible?
Does the Borrello Road overbridge have spare spans for an extra track, namely extension of Platform road to 1800m?

Yeah i'm not an expert at measuring the loops but just took consistent points along the way so i didnt double count.  
Re the bridge, will be interesting to see the plans with the Inland adjustments.  If they can somehow redo the bridge to have a second track on it a bit part of the problem is solved.

Also, somewhere in a NSW infrastructure plan there is chatter of duplicating all the way up to Junee/Coota or wherever the line currently goes from double to single track.

The main south is single track from Wodonga (VIC) to Junee (NSW) interspersed with crossing loops and passing lanes.

The Inland railway, which is single track with crossing loops, branches off the double track main south at Illabo, and Junee-Illabo is double track. Google for "Inland Railway I2S". (Illabo-Stockinbingal).
