The 3820 (Pronounced thirty eight twenty) is a 38 class steam locomotive built in 1947, a sister locomotive to 3830 and its streamlined classmate 3801 who often pull excursion trains.
[edit] Construction
3820 was built in 1947 by the New South Wales Government Railways at the Eveleigh Workshops. It was the 20th of 30 38 class locomotives built to haul express trains and replace the lower powered 36 class on main line working. The first 5 of the 38, road numbers 3801 - 3805 were built at Granville to a streamlined design, whilst the later 25 locos in the class, which included 3820, were built by the NSWGR and were unstreamlined. 3820 was the last 38 class steam locomotive to run in full service with the NSWGR.
The 38 class were first conceived in 1938. They suffered many delays during construction - mostly due to the Second World War. The last of the class, 3830, was built in 1946, 8 years after the 38 class was conceived.
- with 3813 it was the last C-38 Class to be overhauled whilst in regular service, both being overhauled together at Cardiff Workshops (3813 outshopped on 12/12/1968, 3820 outshopped on 13/12/1968), - hauled official last steam hauled ‘Riverina Express’ in May 1964, - last official revenue steam duty on the main south line beyond Goulburn May 1964, - last C-38 in revenue service when withdrawn on 29 December 1970, - worked the official last steam hauled express passenger train in Australia, the ‘Newcastle Flyer’ on 29 December 1970.
[edit] Preservation
3820 is kept as a static exhibit at the NSW Rail Transport Museum at Thirlmere, unlike its restored siblings. 3820 is black with red stripes unlike her green sisters.
