Annie is a steam locomotive that operates on the Groudle Glen Railway on the Isle of Man.

The replica Annie was constructed based upon working drawings; mechanically identical to Polar Bear but with a 0-4-2 wheel arrangement.

The cylinder mould was obtained from the Bennett Brook Railway in Australia, where another replica Annie had been built.

Together with Sea Lion she provides the main traction on the Groudle Glen Railway and can be seen in service at summer weekends on the line as well as some evenings in peak season and various out of season special services, notably the popular annual Santa Trains.

She has been out of service since Easter 2013 for a rebuild which includes new cylinders, works to her side tanks and a new livery.
