<P> The Netherlands use a distinctive "negenoog" (nine - eyed) design shown on the top row of the diagram; bottom row signals are used in Belgium, Luxembourg, France, Germany, and for trams in the Netherlands . The signals mean (from left to right): "go straight ahead", "go left", "go right", "go in any direction" (like the "green" of a normal traffic light), "stop, unless the emergency brake is needed" (equal to "yellow"), and "stop" (equal to "red"). </P> <P> The METRO light rail system in Minneapolis, Minnesota, the Valley Metro Rail in Phoenix, Arizona, and the RTA Streetcar System in New Orleans use a simplified variant of the Belgian / French system in the respective city's central business district where only the "go" and "stop" configurations are used . A third signal equal to yellow is accomplished by flashing the "go" signal . </P> <P> In Japan, tram signals are under the regular vehicle signal; however, the colour of the signal intended for trams is orange . </P> <P> In Hong Kong Island, Hong Kong, a yellow T - signal is used for trams, in place of the green signal . Addition to that, at any tramway junction, another set of signals is available to indicate the direction of the tracks . </P>
