TSS Earnslaw 2019

As part of his extended visit to New Zealand, Phil Barnes had a rendezvous with TSS (Twin Screw Steamship) Earnslaw at Queenstown, South Island on 7th March 2019.

For further detailed information see https://en.wikipedia.org/wiki/TSS_Earnslaw and for information on cruising with her see https://www.realjourneys.co.nz/en/experiences/cruises/tss-earnslaw-steamship-cruises/. (Link broken by September 2025)

The best source of technical information seems to be this page:

The first two pictures show the ship tied up at her Queenstown berth:

The most easily photographed steam elements are the windlass (first, fore) and capstan (second, aft).

There are diamond shaped plates showing the ship's provenance:

The first picture shows one of the pair of locomotive style boilers with twin firedoors, the second classic pressure gauges.

The two large triple expansion engines are mounted in parallel, the low and intermediate cylinders of one are shown right upper. I have seen no reference to the second smaller triple expansion engine on the left, my suggestion would be that it is used for auxiliary power including electrical generation: Presumably there is at least one boiler feedwater pump and another for the jet condenser.


Once a year the Earnslaw is taken out of the water up a slipway for routine inspection and maintenance. Power for this is another steam engine (and boiler) which was once in paddle steamer Antrim.
