Project Genesis is the informal name used for Freightliner Limited’s introduction of the Class 70 diesel-electric locomotives into United Kingdom freight service. Under the British TOPS classification the type is Class 70; the manufacturer, General Electric, markets the family as PowerHaul. The locomotives were completed in the United States by GE and shipped to the UK for operation on heavy freight trains.

Overview and purpose

The Genesis procurement aimed to modernise Freightliner’s heavy-haul fleet with a more powerful, efficient and maintainable locomotive suited to long, heavy trains. The Class 70 design emphasises robust tractive effort and simplified on-track maintenance compared with older diesels. They are intended primarily for bulk freight, intermodal and infrastructure trains where high haulage capability and availability matter.

Characteristics

  • Road designation: TOPS Class 70; manufacturer name: PowerHaul.
  • Diesel-electric drive with modern engine control and adhesion systems to maximise traction.
  • Six-axle (Co-Co) wheel arrangement to spread axle load for heavy freight duties.
  • Design priorities: fuel efficiency, reduced life-cycle maintenance and compatibility with UK loading gauge and signalling systems.

History and delivery

Freightliner ordered the locomotives to replace or supplement older traction on key corridors. The units were assembled in the United States by General Electric and exported to the UK where they underwent acceptance testing before entering revenue service. The project marked one of the significant recent procurements of new heavy freight locomotives for the British network.

Operational use and significance

In service, Class 70s have been used on long bulk trains, intermodal work and occasional special moves requiring high tractive effort. Operators report that modern engine controls and diagnostic systems ease maintenance planning and improve uptime. Their introduction contributed to enhanced capacity on routes where Freightliner operates.

Notable incidents and remarks

One widely reported event during the delivery programme occurred on 10 January 2011, when locomotive number 70012 was dropped from a crane while being unloaded from a ship. The unit fell from a height of roughly 13 feet back into the vessel; the accident caused damage to the locomotive and delayed its entry into service while repairs and inspections were carried out. Such incidents underscored the logistical complexity of importing large rolling stock.
