The submission was made as part of a 12-week consultation being carried out by the East Midlands Mayoral Combined Authority (EMMCA) as part of its ‘Big Transport Conversation’.
EMMCA is working to develop a 15-year strategy for the region, which will initially invest more than £2bn of government funding over the coming six years towards a “joined-up” transport system.
East Midlands Mayor Claire Ward said the strategy should make public transport affordable for passengers, connect communities, and be safe a reliable into the future.
A report published by the LRTA said a future tram network with four different lines could form part of this.
The first line would run west from the Wyvern through the city centre to the Royal Derby Hospital, Mickleover and Mackworth and use the route of the former Great Northern Railway.
A second line would serve Rolls‑Royce in Sinfin, Infinity Park, Chellaston and Alvaston before it would rejoin the first line near the Wyvern.
A third branch would connect the University of Derby’s campuses and Allestree, while a fourth line would link Derby to Nottingham’s NET system via Spondon, Borrowash, Draycott, Breaston and Long Eaton.
