traffic cop fixes the traffic light, Christchurch, 1973

On his Hillman Hunter.  That couldn't be done today -- Occupational Safety and Health would require an approved ladder be used, the worker would have to wear a hi-viz vest, traffic cones would need to be laid out around the corner, a flashing sign would need to be positioned 100 metres in advance of the corner....

the 'Sydney Mail' train at Spring Bluff near Toowoomba, circa 1910

From the look of it, a PB15 4-6-0 in front. In those days the break of gauge meant this consist only made it to the Qld/NSW border at Wallangara where it was 'all change' to the other platform to continue into NSW.  Spring Bluff station still exists and in fact is one of the most beautified in Australia, see here
