Meet Nellie —
a little engine with a big heart

Nellie is a 4-inch scale Burrell road locomotive — about a third of the size of the full-sized engines that once hauled heavy loads along Britain's roads. Don't let the "scale" fool you: she's a genuine, coal-fired, steam-powered engine in every respect, just sized to fit on a driveway rather than in a farmyard.

She's a single crank compound (SCC) — a clever Burrell design where high- and low-pressure cylinders work together on a single crankpin, squeezing every last bit of work out of the steam. She wears the classic Burrell Crimson Lake livery with lining, just like her full-sized ancestors.

And her size is her superpower: at a third of full size, all the whirring motion — cylinders, cranks and gears, right at eye level — can be seen and understood in a way you never quite manage on a full-size engine. Youngsters love it. So do their grown-ups.

Nellie was five years in the making — and she's no kit engine. Her major components were scratch-built and machined from castings, working from drawings supplied by Live Steam Models. Her boiler was started in 2016, the build was completed in 2021, and she's been fully UK road legal since her first registration in 2023.

Home is Bournemouth, Dorset, but you'll find her at steam rallies across the South of England (with the odd wander up to the Midlands), at family fun days, and — on quiet weekends — pottering around the local neighbourhood, waving at everyone she meets. She travels with her ride-on trailer, so wherever she goes, rides usually follow.

Before lorries ruled the roads, steam traction engines did the heavy lifting of Victorian and Edwardian Britain — ploughing fields, threshing corn, hauling timber and driving fairground rides. From the 1860s to the 1930s, these magnificent machines were the beating heart of rural industry.

The mightiest of them — road locomotives, like Nellie's full-size ancestors — moved loads nothing else on land could shift. Pioneering heavy-haulage firms such as Norman E. Box of Manchester and Edward Box of Liverpool hauled ships' propellers, boilers, transformers and even railway locomotives behind their engines, well into the age of the lorry. Box photographed nearly every job for publicity, and those images — a road locomotive dwarfed by its load, crowds gathered to watch — remain some of the most striking records of the steam age. Happily, several of those engines survive in preservation today.

Charles Burrell & Sons of Thetford, Norfolk were among the finest builders of them all — in an age when Fowler of Leeds, Garrett of Leiston and Aveling & Porter of Rochester were household names in the countryside. From their St Nicholas Works, Burrell produced agricultural engines, showman's engines and road locomotives renowned for their quality and good looks — many wearing the deep crimson that Nellie carries today. The Charles Burrell Museum (opens in new tab) in Thetford tells the company's story today, in the very buildings where the engines were built.

Burrell's patented single crank compound system, unveiled at the Royal Show in 1889, became a hallmark of the marque: two cylinders — one high pressure, one low — driving a single crankpin, giving the efficiency of compounding with a simpler, more compact motion. Nellie is a working tribute to that ingenuity, a third the size but every inch a Burrell.

Best of all, this isn't just history: full-size Burrell SCC road locomotives survive in preservation and still take to the roads in steam. Spot one at a rally and you've met one of Nellie's big sisters — three times her size, and the family resemblance is unmistakable.
