On 28 April 2013 a substantial wooden railway bridge on the Murwillumbah Casino Railway line was noted removed. It is the bridge over Tunnel Rd near the Tunnel Rd / Bloodswoods Rd intersection, south of Stokers Siding NSW. S 28° 24.558 E 153° 25.367 UTM: 56J E 541411 N 6857383    Not sure when removed?  


The following has the pictures of the road with the bridge removed as well as the Google Earth Street view, dated February 2010, when the bridge over the road was in place.

I take it the bridge was in exceptionally poor condition?

Sorry, no definite idea why removed. But, if condition was the criteria then there would be many wooden bridge removals but last week we saw several wooden rail bridges in the Lismore region still in place. We have since been advised privately it was missing before late last year.

Bridges in poor condition are generally only removed if there is a danger of parts of the bridge falling on to the road.
Because one bridge is in poor condition doesnt mean that all other bridges of the same type are in the same condition.

We were in that area for non railway related purposes and only chanced upon the fact that the bridge was gone.

Some time ago the eastern rail at the Mullumbimby level crossing was removed, and the space filled with hotmix.

More events which give the lie to the term "Booked out of use".

That is simply used as an excuse to avoid formal closure processes until the line has rotted away at which point, with few who remember trains passing along it left to say "Boo" it is quietly closed and the easement sold off.

It is also not entirely unknown for bridges and other infrastructure to be removed as part of road safety improvements or indeed as theft.

I have received private communication including photographic proof that the wooden bridge was gone by Sunday, 12 August 2012. The pictures include people so I not able to publish the images or pass the images around.

Apparently, a section of the far Main North was destroyed after the RTA built a diversion through it; due to flooding, the armed forces had to blow up a section of Main West as well.

In some cases of a non-closed closed line, a resident may request for infrastructure for be removed (such as a farmer wanting a low bridge removed to improve equipment access to their farmland).  However, I understand that they are then required to pay for the bridge (or whatever) to be replaced if the line is resurrected within a certain amount of time (although I suggest such a demand would never eventuate even if the line were rehabilitated).

The most likely cause is that the part of the bridge thats been removed has been deemed a hazard to traffic passing underneath.
Railcorp would be liable for any damages caused if any part of the bridge fell onto the road causing damage to vehicular traffic.
Sect 99B of the Transport Admin Act allows for this .

Since this line will unlikely see traffic again, it sounds like a sensible move as opposed to spending money on a bridge that will won't be used again.

Nyngan major flooding in the 1990s was the reason a stretch of the main western line near the town was blown to allow thev waters to recede line was rebuilt after the floods receded.

It was 1989, it was just North West of Nyngan nr West Bogan road and the line was never repaired.

There were floods in 1989 and 1990. The 'infamous' floods were April 90.
The Army Reserve did the blow-up was actually in 1990 floods.
The line was blown about 4km NW of the town towards Bourke along the flats, not the Cobar branch.

I think what Draffa has said may be pretty close to the mark.  Judging by the photos it shows the removed section as being over the road passing underneath, the whole section comprises timber trestles & piers.  Depending on how much traffic uses the road especially trucks, the clearances may be too tight for many trucks in the area to safely go under the span, which restricts transport links in the area.

One thing to remember in these heavy timbered areas is the aspect of white ants, & if its an area that white ants are prevalent in, then it does not take long for them to become very active & destroy the bridges & sleepers along the line, takes around 6 months of non use for them to start to eat through the timbers.

Hi a6et, re following remark; takes around 6 months of non use for them to start to eat through the timbers.

I was not aware that traffic changed the way white ants and similar animal borers attacked bridge timbers? Do you have any more on this please as it is an interest area of mine?

During the 70's - 80's when lines were in many ways reclassed by Shirley from general traffic to wheat or grain only lines, then & later Hill when he had many classed as low volume wheat only lines, which led to their eventual closure.  The issue of white ants infecting the sleepers on all of the many branch lines was raised.  Many believed the old saying of white anting the lines & anything else in a similar category was no more than a throw away line, was actually quite true.  As each of the lines that were not closed & only deemed suspended for seasonal conditions, there was a program set up to ensure the lines had an inspection car run over them in each 6 month period after the last train had run over the line.

Prior to reopening for their next season the same thing had to be performed again to ensure the sleepers were in good enough condition.  All it took apparently in those areas was for there being no movement or vibration through the timber sleepers for the white ants to get into the sleepers & eat them out, & they condition could not be detected from the outside, as the white ants when doing the job only eat the internals of the sleepers & anything else.  They can eat wood away totally on painted surfaces, & the only way you would know about the problem is if you touched the paintwork.

We rented a house in Cedar Party at Taree, & discovered white ants had come through & made a nest in the rear condenser of the fridge. A pest exterminator came out & went to go under the house & when he tried to pull the slip bolt out to open the man hole door the whole thing collapsed, there was virtually nothing left of the door except the paint, & slip bolt which was only in place owing to the bolt being in the brickwork. First time I ever saw that & understood what was talked about when in the NW area.

The mid sized petrol fettlers cars were used for these inspections & on one location near Warialda Rail the trike came off owing to the amount of sleepers that had been eaten out by the white ants, as the previous inspection had shown up no problems.  When approaching the sleepers that crumbled they looked in good order but the weight of the trike on the sleepers just crushed them.  When the ganger got out & trod on others the white ant activity was intense.

While 6 months is the deemed time, it can be sooner depending on the area.

One could call this "Demolition by Neglect".

eg;  no trains, therefore no sleepers, therefore no trains.  QED

What was the clearance of the old bridge? Was it too low?
