This 230 h.p. locomotive was one of a batch of 91 built at the Diephulzer Works near Bremen, Germany, in 1979 for the Taiwan Sugar Corporation. It carries the Diema trade name and was delivered new to the sugar factory at Sanhua in Tai-nan County, some 300 km south of the capital Taipei. Here it would have been a common sight in the area working 600 tonne trains of raw sugar cane from the fields to the factory for processing. With the import of cheaper cane from Indonesia and consequent cut-backs, the opportunity to obtain one of these powerful locomotives was taken and ours, Taiwan Sugar Corporation No. 175, arrived at Llanfair on 19th April 2004.
