3820 is a 4-6-2 steam locomotive operated by the New South Wales Government Railways between 1947 and 1970. It has been preserved by the NSW Rail Museum, Thirlmere.

3820 was built in 1947 by the New South Wales Government Railways', Eveleigh Railway Workshops as the 20th of 30 38 class locomotives built to haul express trains. The first five were built by Clyde Engineering to a streamlined design, whilst the later 25 locomotives in the class were built by the NSWGR's Eveleigh and Cardiff Locomotive Workshops and were unstreamlined.

Construction was delayed mostly due to material shortages during World War II. It was at various times allocated to Eveleigh, Enfield, Lithgow and Broadmeadow locomotive depots.[1]

During the rundown of steam operation in New South Wales, 3820 had the distinction of some lasts:[1][2]

  • 13 December 1968: was the last C38 class to be overhauled whilst in regular service, both being overhauled together at Cardiff Locomotive Workshops
  • 29 December 1970: worked the official last steam hauled express passenger train in Australia, the Newcastle Flyer[3]
  • 29 December 1970: last 38 class in revenue service when withdrawn
