5 inch gauge Polly VI - stock code 10173

A 5 inch gauge "Polly VI", one of the largest engines in their range - we like this design with it's handsome, rather colonial style outline.

Unused in recent years, it's been through the workshop here - recommissioning work included stripping and servicing the lubricator and axle pump and fitting a new injector. The boiler has had hydraulic and steam test with new certification issued.

A well put together engine, it steams freely and runs particularly well with crisp, even exhaust beats - here's some video of it running on the rolling road here.
