DTG Inc is the Christchurch-based operator of a fleet of ex-New Zealand Railways diesel-electric locomotives. Our fleet represents the full collection of NZ locomotives built by the English Electric Company and is a historically significant collection of early New Zealand diesel traction. We are based at Ferrymead Heritage Park. Our locomotives are used on passenger trains and heavy shunting services on the Ferrymead Railway. Our locomotives also work on other heritage/tourist railways and charters on the national rail network. We are a member of FRONZ (Federation of Rail Organisations of New Zealand).
