These small steam locomotives were built at the Caledonia Works, Kilmarnock, of Andrew Barclays and Sons Ltd in Scotland. They are 0-4-0 wheel arrangement saddle tank engines (meaning the water tank is on top and around the boiler).

 

“No 3: Brian Harrison” spent its working life at the Central Electricity Generating Board‟s Power Station at Ferrybridge near Knottingly in Yorkshire, a period of some 16 years, before being replaced in about 1970 by diesel engines. Brian Harrison was despatched to store at Tinsley in Sheffield it remained for some 35 years until being acquired on long term loan by the Ecclesbourne Valley Railway Association, who have agreed to restore it.

 

There are a large number of this type of locomotive in preservation, in particular with the Ayrshire Railway Preservation Society, the Swindon and Cricklade Railway, Bowes Railway, East Anglian Railway Museum, Buckingham Railway Society etc. Brian Harrison had been kept under cover and its livery was intact. It was restored to working order and has been lovingly maintained ever since.

 

It is common to see No. 3 running from platform 1 at Wirksworth on special occasions, offering "driver for a fiver" trips or platform 3, running up the steep incline to Ravenstor.
