3 1/2 inch gauge OS BR Class 7 "Britannia"

A 3 1/2 inch gauge OS Britannia, an older engine showing signs of wear to the paintwork.

Unused in recent times, the boiler has had a hydraulic test in the workshop with new certification issued. As expected from an OS engine, it runs well on air in both directions - they do tend to go like sewing machines!
