Having just acquired some foreign motive power .I thought it would be interesting to compair the difference's in what was the ultimate development of the steam locomotives in Victoria and New South Wales.
Having always assumed that the mighty 38 and 57 class was the biggest and best .Its a little embarrassing to find out that those damn Victorians had bigger ones than us in the form of the S Class and of coarse Heavy Harry.
The S Class originally built in 1928 had there tenders increased in size when they where converted to oil burners and streamlined and this is the model I will use to compare.
HH was designed as a passenger loco to haul the Overlander .Because the bridges and track on route where never strengthened it was relegated to freight haulage between Melbourne and Wodonga so we should compare it to the 57 but this still doesn't help matters.

We can find some solice in the fact that the AD60 Garratt beat HH in weight bye 4 tons but which ever way you look at it HH220 was a monster.But then again the 57 could beat it in tractive effort by 9,300 lbs with 20 lbs less boiler pressure and 32 tons less weight. Making the 57 the clear winner in the weight on rails for pulling effort which is what this design competition is really about.
But if you consider a loaded Big Boy tender at 200 tons . The HH would probably would look like a shunter to the yanks.
