|Broad Gauge O-class 2-8-0 locomotive|
This is the first locomotive to have the O class classification (see O 204 for second O class).
The two engines forming the O class were broad gauge engines imported from the United States of America for use on goods services on the Adelaide hills line. When introduced, they were the largest locomotives in service on the South Australian Railways. They were not very successful performers on the hills line and consequently were diverted to the north line. Orginally these engines where designated as the M class, but it was sometime later changed to O class.
