text: The tram, which currently serves the Nottingham area, would also run to East Midlands Airport and the proposed HS2 station at Toton.
  The 19 councils in the region described the scheme as one of several "priority projects" in devolution negotiations.
  The timetable and costs of the project are not discussed in the document.
  The information was revealed in a document detailing requests to be made from the government as part of a deal to devolve power.
  Andrew Braddock, chairman of the Light Rail Transit Association, which supports the project, said the trams would be an efficient and effective way of moving passengers from the HS2 station to the cities of Derby and Nottingham.

  "There have been a rash of modern new tramways across France as city mayors say... it's time we took the streets back for the people.
  "In Germany, they've had trams since the 1880s and were sensible and kept them."
  A transport review in 2013 estimated the cost of a new tram line at £20m for each mile of track, putting the cost of a link from Toton to Derby at about £200m.
  Another cost estimate for a tram line from Nottingham to Ripley in Derbyshire via Eastwood, Kimberley and Langley Mill was put at £180m.
  The document said the East Midlands councils are determined to "reach a unified position on the strategic transport interventions required to maximise the growth potential of the region".
