5 inch gauge Polly "Prairie"

A Polly Models "Prairie", the largest locomotive in their well-regarded 5 inch gauge range; to our eyes a most handsome design.

A one owner engine, this one has come to us as part of a complete private railway along with a Polly "Trojan", rolling stock and track. It appears to have had little use from new and remains in excellent mechanical condition, very smartly turned out in Great Western green.

The CE-marked silver soldered boiler has had recent hydraulic and steam tests with new certification issued.

The engine runs as well as it looks, mechanically quiet with well-defined exhaust beats. It steamed freely on the rolling road, there's some video of it here.
