Aboriginal People, mostly of the
Dharug and
Gundungurra people, lived in the area for thousands of years prior to European
colonisation. One of the First mentions of the area by Colonisers was by
William Cox in 1814 during the Construction of the first road across the Blue Mountains. Referencing what it now known as
sun valley he noted: " Water and Forest growth in the valley to the right". Some of the First europeans to come in the area where attracted to the flat area and rich soil of Sun Valley. Which was conveniently located close to the Western Road and made it a prime resting spot for Farmers transporting Cattle from Bathurst to Sydney. In 1830 "The Valley Inn" was established, later renamed the Woolpack and then the Welcome Inn. In 1847
Governor Fitzroy Stayed there. Following the Establishment of the Railway line the Inn went out of business and the property was purchased by
Geoffrey Eager in 1870 as a mountains home. In 1902 he renamed the Inn Wyoming and operated as a boarding home until 1937 when it was demolished. He established a private Railway station there, called Eagers Platform. In 1877 it was renamed to "The Valley" Station. In 1880 it was renamed to the "Valley Heights Station" becoming the location of the modern
Valley Heights railway station. The Railway Station was destroyed by a bush fire in 1911. In 1913 a locomotive depot was established. Due to the steep gradient around the station two major crashes occurred during this time period. In 1923 a goods train crashed near the station and in 1926 a train lost control and slid down the mountains before being stopping in
Blaxland. The Station was electrified in 1957. In 1989 the Depot was closed and used to store material until 1993. In 1994
The Valley Heights Locomotive Depot Heritage Museum was established on the site of the depot and a steam tramway was added in 1997. ==Heritage listings==
