When the O-Train closes overnight, some Frequent routes are extended beyond their O-Train connection to Rideau Station downtown. These extensions are known as Night routes. Night routes run until O-Train service starts up in the morning.
Their route name begins with N.
Their symbol is a white hexagon outlined in blue next to a black rectangle containing a yellow letter N and moon icon.
Night routes are extensions of routes that run during the day. They will serve the same stops and stations up to the N extension.
