High Speed North, sometimes called Northern Powerhouse Rail or High Speed 3 (HS3), is a high speed railway across the North of England that was proposed in 2015 by Transport for the North (TfN). The east–west trans-Pennine line would provide a high speed link between northern cities such as Liverpool, Manchester, Leeds, Sheffield, Newcastle and Hull, with connections to HS2. In March 2016, the National Infrastructure Commission's report, "High Speed North", recommended collaboration between TfN and HS2 Ltd on the design of the northern parts of HS2. Some redesign of HS2 would be needed to link into HS3. The proposal was given approval in the March 2016 budget.
