Content: The locomotives ordered were intended to match older types in terms of haulage capacity whilst at the same time being more fuel-efficient. The project was a collaborative effort between Freightliner and GE, with input from drivers on the cab design. The locomotives utilize a GE PowerHaul P616 diesel engine rated at 2,750 kW (3,690 hp). the locomotive meets EU Tier IIIa emission regulations. Freightliner expects that the locomotive's efficiency is 7% better than contemporary models, with a further 3% increase in efficiency whilst braking; regenerative braking is used to supply the energy to power auxiliary motors. The locomotives were given the Class 70 TOPS code, breaking the previous convention that class numbers in the 70s were used for DC electric locomotives . The new locomotives are similar in appearance to a Class 58; a hood unit design with a narrow body typical of locomotive types in use in North America, the cabs are accessed from the rear via exterior walkways on the narrow part of the hood. The distinctive front end shape is due to crashworthiness features It is also fitted with air conditioning and acoustic insulation to improve the crew's environment, making it an improvement over the Class 66.
