The New Zealand DH class locomotive[nb 1] is a type of diesel-electric heavy transfer and shunting locomotive in New Zealand's national railway network. The class consists of six heavy shunt U10B type locomotives built by General Electric United States at their Erie, Pennsylvania plant[2] in 1978.[4][1] Five of the class are used in the Auckland area for heavy shunting duties, including services around Auckland and the Port of Auckland, while one is based at the Port of Tauranga in Mount Maunganui.[4]
