The builder for the new Midland Metro trams has not yet been decided; the tendering process has reduced the number of bidders down to four or five applicants at the current time.
Therefore the images of the new trams are just generic artists' impressions that aren't intended to represent any particular tram design at this stage (For a start, the images at New Street have display a destination of "Brierley Hill" on the trams!), and they certainly won't be driverless.
