|Hi Herb ,if you have a closer look,I think you will find the rails are are one plank(3 x 4 ?)with a flat bar pinned(1. 1/2 x 3/8 ?)to the top of the plank.You can see a height difference on the rail top near the trolley wheels and a shadow in the rail tops for the length of the rails,also there are round dots on the bar above the ties.I would assume these pins(bridge nails) go through to the ties to keep the guage. This was a common practice in Australia on wooden tramlines,especially on the outside rail on curves,or where very heavy loads were being carried(The last step before going to steel rail as a cost saving) Peter.
