Why this model matters
Introduced during the 1980s, the 81 Class became the backbone of heavy freight operations for the State Rail Authority of New South Wales. Locomotive 8171 in the SRA Mk2 livery represents this significant period in Australian rail history, hauling container, grain, coal, and general freight services. The factory-fitted DCC sound system enhances authenticity with realistic locomotive audio and lighting functions.
How to use it
Place the locomotive on compatible HO gauge track and operate it using a DCC controller to access the full range of sound and lighting features. It can also be used on compatible analogue layouts where supported by the manufacturer. Pair it with HO scale freight wagons to recreate authentic Australian freight operations.
This is a ready-to-run model locomotive. It is not a toy and is recommended for collectors and modellers aged 14 years and over.
