Today's historic photo of the day: Rail flaw detection vehicle SRS141 passes through Hawkesbury River, NSW, September 5 1983.
SRS141 was built in 1928 in St Louis (USA) as a passenger #railcar for the Chicago, Rock Island & Pacific Railroad. In 1972, it was converted by Sperry to provide rail flaw detection services to US railroads.
In 1973 it came to Australia, and roamed the NSW checking for rail flaws. It eventually returned to North America certainly by 2002, and is still in use over there
