A University of Otago lecturer wants a special railway line between Christchurch and Dunedin set up for students to travel between cities.
Otago Business School senior lecturer Dr Duncan Connors says it's one way to lower emissions created by the roughly 2,000 students who travel at the start of each semester.
Connors says the 'Harry Potter' style of transport would keep students out of gas-guzzling vehicles.
Connors spoke to Morning Report.
