Another important exhibit is Locomotive No. 1, the first steam locomotive to haul a passenger train in New South Wales, built by Robert Stephenson & Company in 1854. The most popular exhibit is arguably "The Strasburg Clock Model", built in 1887 by a 25-year-old Sydney watchmaker named Richard Smith. It is a working model of the famous Strasbourg astronomical clock in Strasbourg Cathedral (which at that time was called Strassburg or Strasburg). Smith had never actually seen the original when he built it but worked from a pamphlet which described its timekeeping and astronomical functions.
