The Valley Heights Locomotive Depot Heritage Museum is a railway museum located in Valley Heights, New South Wales, Australia. It is operated by the Blue Mountains Division of Transport Heritage New South Wales. The Valley Heights Steam Tramway is also located in the former locomotive depot. The facility is located 300 metres north-west of Valley Heights railway station. ==Locomotive depot== The locomotive depot was constructed in 1913 when the duplication of the line between Emu Plains and Glenbrook was completed. The depot was available for service from December 1913, but was not officially opened till 31 January 1914. With the duplication and regrading of the line, the heavy grades below Valley Heights were eliminated, the ruling gradient from Penrith to Valley Heights being 1 in 60. The depot at Valley Heights consisted of a locomotive yard, a 10 bay roundhouse, turntable, an elevated coal stage, and water tanks and columns. It provided bank engines for trains travelling to Katoomba and beyond. The engines at Valley Heights not only banked over the longest distance in NSW, but also had the envious distinction of having to operate over the longest continual and most steeply graded mainline in Australia. The 33 kilometre section from Valley Heights to Katoomba rises 670 metres, with a ruling gradient of 1 in 33. During the steam era, the depot had a continual allotment of eight freight and two passenger engines. During the peak of the steam era, an average of 30 trains during any 24-hour period required banking from Valley Heights to Katoomba. The western line was electrified to Valley Heights in October 1956. In February 1957, steam operations from Valley Heights were replaced by the 46 class electric locomotives. The depot in latter years was an electric locomotive and freight wagon repair workshop, the electric engines receiving everything from minor repairs to complete overhauls at the depot. A variety of freight wagons were also repaired. The demise of Valley Heights depot began when the more powerful 85 class locomotives were introduced in 1979. The demise was accelerated with the introduction of the 86 class locomotives in early 1983. From the mid-1980s, the number of trains requiring banking from Valley Heights had been reduced to a handful each day, the number of locomotives required for this duty being reduced to three, sometimes as few as two being necessary. In October 1988, it was announced the depot would close.〔"Valley Heights to Close" ''Railway Digest'' December 1988 page 439〕 One electric locomotive remained available for any bank work necessary, until the last week of January 1989, when 4627 had the distinction operating the last train to be banked from Valley Heights to Katoomba.
