Peter Witt car 1597 at Piazza della Repubblica on 21st April 1992. This type of car is named after Cleveland street railway commissioner Peter Witt, who designed it for Ohio around 1915. The concept was to speed loading by putting the conductor in the middle of the car, letting crowds board through the front door and paying as they passed the conductor.<br />
Milan has the longest-serving Peter Witts in the world, building some 500 from 1928. The first Peter Witts in Milan were painted an attractive yellow and white; in the 1970s, the Milan tram fleet was repainted a solid orange. The Peter Witt trams no longer use conductors.
