Tasmanian Government Railways J class

The Tasmanian Government Railways J class was a one locomotive class of 2-6-4-0 steam locomotives operated by the Tasmanian Government Railways. It was known as Hagan's Patent.

History
To operate trains on the North East Dundas Tramway, the Tasmanian Government Railways purchased a locomotive from Maschinenfabrik Christian Hagans, Erfurt in 1901. The locomotive had an articulated 2-6-4-0 wheel arrangement. Its weight played havoc with the light rails it ran over and in 1910 it was replaced by the K class.
