Its 3.4-mile route links some of the most vibrant destinations in the river cities.
The trolleys operate on an overhead power supply and travel across the Main Street Bridge over the Arkansas River to connect the two cities. Passengers not only have great views of the river and the Little Rock skyline, but can see the U.S.S. Razorback, a World War II submarine now owned by the City of North Little Rock and anchored on the river's north shore.
River Rail Manager Virginia Fry says the system runs full service of its green line and blue line (two cars each) Monday through Saturday with reduced service of one car for each line on Sunday.
It costs adults one-dollar to ride and 50 cents for kids 5 to 11.
A day pass is also available for two-dollars.
More than one-million people have taken a ride on the system since service began.
The River Rail's blue line goes over the Main Street bridge into North Little Rock while the green line operates only in downtown Little Rock.
