Location: Western Australia
Tommorrow for the next 3 days according to the Weekly Notice, the Brunswick River Bridge in Brunswick will be replaced. All three spans, 2 long and one short will be replaced. The current bridge is the steel beam with timber sleeper type typical of this area, and the new one is a ballast deck bridge. There is a 500T crane in place, appears fully setup now for lifting tomorrow. I assume at this point trains will either run round in Brunswick, and reverse into the junction from the south, for travel north, or run all the way to Beela and run round their train. When the cross over on the Collie branch in Brunswick was being worked on Worsley trains ran to Benger, ran round their train and come back, so I imagine this occaision will be similar for Alcoa trains. I imagine the Australind will also do the same. I am not sure how long it will take to complete the lift but I imagine the final day/ day and a half will be track laying and ballasting/ tamping.
How the shunt will occur with the ACN's I do not know. I am suspecting they are being moved off the mainline services and replaced with either S or DB class for the duration. I do not believe the ACN's can be driven hood first, and without a junction to turn on, cannot run round their train and continue. It is possible they will put a DB class with the ACN's or one on the other end of the train to eliminate running round. Will have to wait until tomorrow to see what happens.
