Heavy Harry: The Biggest Steam Locomotive Ever Built in Australia Couldn't Cross Its Own Bridges

H220 is over 28 metres long. It's the largest steam locomotive ever built in Australia. And it was too heavy to run the route it was designed for.

That last part tends to catch people. A locomotive built to haul The Overland between Melbourne and Adelaide — found to be too heavy for several of the bridges on that line. The infrastructure couldn't take it. H220 still worked, still hauled, but not always where originally planned.

The nickname came naturally: Heavy Harry.

This 2025 50c Coloured Uncirculated Coin from the Royal Australian Mint's Steam Giants – Australian Rail Heritage collection features H220. It's part of a series covering Australia's significant steam locomotives, and Heavy Harry has one of the stronger stories in the set.

Victorian Railways built the H Class for interstate passenger work. The Overland was a prestige run — Melbourne to Adelaide, long distance, the kind of service a railway puts its best power on. H220 was that power. Over 28 metres of it. The weight that earned the nickname also meant parts of the route couldn't hold it, which is the kind of outcome no engineer wants to report.

H220 is now at the Newport Railway Museum in Melbourne. It's worth seeing in person — 28 metres of steam locomotive reads differently at ground level than in any photograph. Newport holds a solid Victorian Railways collection, and Heavy Harry is one of its main exhibits.

The coin: 31.51mm diameter, 15.55 grams, copper-nickel, uncirculated finish. Mintage capped at 35,000. Price $17.50.

Heavy Harry has name recognition that most locomotives in this series don't. It's known beyond collector circles — the size record, the bridge problem, the nickname. For anyone buying coins in the Steam Giants range, this is one that comes with a story worth telling.
