The first Hunter Valley Steamfest was held in April 1986 to commemorate the days of steam, three years after steam operations on the South Maitland Railway ceased. In 2017, Steamfest attracted 50,000 visitors. The 2020 event was cancelled due to the COVID-19 pandemic.
Locomotives
Hunter Valley Steamfest has seen different locomotives from over six different preservation organisations within New South Wales and even one from the United Kingdom. This list contains the locomotives that have attended the Hunter Valley Steamfest: Local area of Maitland

During the Steamfest, trips to Broadmeadow, Branxton, Singleton, Paterson and Dungog are operated by both steam and preserved rail motor. The Sunday Barrington Bullet travels to Dungog, then to Stroud Road loop and return. In 2015, a new trip to Port Waratah was introduced. In the early years of the festival, steam hauled charters brought passengers to the event but this is no longer the case with the locomotives and rolling stock moving to the festival empty. In 1986 two trips from Sydney Central and another from Blacktown operated. In 2013 and 2014 passengers were able to travel on the stock movement from Picton to Maitland, albeit on the Friday before and Monday after the festival.
The Great Race
One of the excursions involves a race between one or more steam locomotives and one or more de Havilland Tiger Moth. In 2010 a triple parallel of 3265, 3642 and 3526 was organised taking months of planning. The locomotives raced against three Tiger Moths and winner of the race was the oldest loco in the race, 3265. A Tiger Moth eventually won the race for the first time in 2012. In 2016, the race was between four trains and four Tiger Moths.
