By: Robert Brown1st Aug 2022 9:24AMThis is not construction as it is after the floor strengthening, so late 1920s at earliest. The transoms have been changed to single track, not full width across both tracks. When zoomed in, the end of the cross girder can be seen below and to the right of the lifebuoy. The end of the cross girder’s top flange has rivets, and is well below the transom top face/bottom of rail, indicating the stringers have had the BFB added to the top flange. The presence of rivets in the end of the top cross girder flange indicates that the additional plates comprising the cross girder strengthening have been added as the original doubler plates were not full length of the cross girder. In addition it is highly improbable that such abrasive blasting equipment existed in 1889.
