Can you Spot the Difference? [Sydney Harbour Bridge]

State Records NSW is highlighting a number of anniversaries on its website this year. The Sydney Harbour Bridge features in two of these.

First Passenger Train to Cross Bridge

Between when this image was taken in 1932 and when our second photo was taken in 1952, the Bridge changed.

    Well spotted to both beachcomberaustralia over on the Flickr site and to David Bromage. And in record time too. We thought these photos might have kept you guessing for a little while.

    For further information see our War and Australia webpage where we have posted material concerning the use of the Bridge pylons by the military and the raising of Lewis machine guns to two of the pylons.

    The 1932 photo shows 1500v overheads for the pantograph fitted train sets.

    The 1952 pic had 600v overheads for tramcars.

    I can advise a lot more tech data. I worked at Randwick tramway depot, and at ELCAR in Chullora on railway trains 1946 to 1952.

    Thank you, Alistair. Yes the photographs are taken from a slightly different angle.

    The 1932 image has the overhead wires for trains in the foreground and the wires for the trams on the eastern side of the bridge can be seen in the background. The 1952 image has a good closeup of the tram wires with the train wires in the background. The lane that was used for trams is now a roadway.

    Well spotted, Richard. The flagpoles in the outer corner of each pylons (and the flags that are flying from them) are not present in the 1952 image.

    Digital image 12685_a007_a00704_8734000109r
    entitled Public crossing Bridge after Opening Ceremony, 19 March 1932
    is the clearest image I can find that shows the flagpoles on two of the pylons. It can be accessed vis Photo Investigator on our website.

    I wonder if they were removed in 1942 when the gun emplacements were installed or at some other time?

    My name is Michael Leichsenring and I am a serving soldier in the Australian Army. I am doing some research on the history of Australian Air Defence.
    I am interested in researching the anti-aircraft gun emplacements apparently constructed on each of the Bridge’s pylons during WWII. In a prevous comment reference was made to, ‘the raising of Lewis machine guns to two of the pylons.’
    Can anyone please elaborate on this by providing achieve references (documents and/or photos)?
    Regards, Michael

    NRS 9771 Correspondence files – Miscellaneous, 1932-1978 [Department of Main Roads], File 42m457 Anti-Aircraft Defence – Sydney Harbour Bridge, 1942 [10/27345] contains information on both the building and the decommissioning of the anti-aircraft gun platforms, and the changes made to the Bridge pylons to accommodate the anti-aircraft guns. One report dated 8 December 1942 states that there were three military units in occupation on the Bridge: a machine gun and flood light unit, the bridge guards, and the anti-aircraft battery.

    The file states that the officer in charge for the positioning of the guns in 1942 was Captain G Vincent of 221 Light Anti-Aircraft Battery. The anti-aircraft guns were located in the south-eastern and north-western pylons. There is also mention of sleeping accommodation being made for soldiers in the pylons, although details are not given. The anti-aircraft guns were removed on 23 October 1944. In a report on what would be needed to remove traces of the Army’s occupation, dated 8 November 1944, Item 2 and 3 are removing 8 x HD bolts from the south-eastern and north-western pylons, Item 4 is sealing 4 x MS cover plate and Item 5 is removing 8 x Lewis gun bed-plates.

    There is also information of our Digital Gallery War and Australia: World War II in the section called ‘Protecting NSW’
