Roelands/Burekup Railway Bridge Replacement

 
  DBclass Chief Commissioner

Location: Western Australia
7 bridge spans turned up this week at Brunswick Junction for the replacement of the railway bridges (5 span + 2 span) between Roelands and Burekup. They are the ballast deck type. For approximately one and a half years there has been a 40kph speed restriction over the bridges for reasons I can only speculate as being due to the sleeper condition on the bridges. I do not know if there are structural issues with the steel work but I would think not. I do not know when they will be replaced exactly but it will happen sooner then later. So get your photos while you can. The old South Western Highway alignment adjacent the bridges affords an easy time finding locations to take photos. Please note tresspass laws where applicable.

Testing the brain cells out, the original bridge is a transom deck bridge (correct?).

The issue was the bridge was designed as a standard gauge bridge.  The transoms laid with the NG rails that put a moment through the transom and not a direct transfer of mass from the rail being above the bridge beam.

So maybe the deck upgrade is part of removing the transom issues.

I was once told the abutments were made to suit standard gauge but I think you are right the beams themselves are made to suit standard gauge rail as the rail is inside the beams and not directly above it. I was under one of the bridges and I did notice a sideways movement to the beams as the train goes over which I put to poor sleeper condition loading the beams incorrectly. I have been told the fixed nature of the rail causes some minor track issues as the rail cannot move at all, and I would imagine that during track maintenance that the bridges would cause a pain.

Anyone have any clues as to when this is going to happen? I thought it would have occurred by now. They are building up the ballast pile at Brunswick. Could be unrelated though.

Old bridge spans removed, they are preparing for the new ones. Railway crossing at Picton on the southwest highway is being worked on, about half a km of rail between DBC in Picton is being worked on also and apparently rail at the Worsley Alumina site is being worked on. It’s all happening in the Southwest this week.
