opening to 2025. Transit links The Northstar Line commuter rail line connects downtown Minneapolis with northwestern suburbs, with a station at the north/western terminus of the Blue and Green Lines. The two light rail lines share trackage through downtown. The eastern terminus of the Green Line is a street level station in front of the Saint Paul Union Depot, considered one of the great architectural achievements in the city and formerly one of the main points of departure for area train riders up until passenger rail service in the United States was restructured in the 1960s and 1970s. The concourse of the Union Depot is planned to become a transfer point for people coming into St. Paul along the proposed Rush Line and Gold Line bus rapid transit lines. As of June 2014, Union Depot is a transit center for Metro Transit, MVTA, Jefferson Lines, Megabus, Greyhound buses and Amtrak's Empire Builder. Bus service Metro Transit Route 16 parallels the Green Line between St. Paul and Fairview Ave Station. Route 50 formerly operated alongside Route 16 during weekdays, but with stops generally spaced about one-half mile apart. It was discontinued when the Green Line entered service. After the Green Line opened, Route 16 service was cut back from 1 AM to 5 AM, frequency was reduced to every 20 minutes and the route was truncated at the University of Minnesota. In 2010, route 16 had an operating budget of $10 million and generated $3.7 million in revenue (a farebox recovery ratio of 37%), while Route 50 had a 2010 budget of $3.5 million and generated $1.3 million in revenue (37% farebox recovery ratio). Route 16 carried about 5 million passengers, with weekday ridership averaging 16,880 and Saturday and Sunday ridership averaging 12,082 and 7,110, respectively. Route 50 carried about 1.5 million riders over the course of the year, with weekday ridership averaging 6,886. Metro Transit also provides weekday express bus service along Interstate 94 between the St. Paul and Minneapolis downtown areas. Vehicles Siemens Industry Incorporated built 47 S70 Light Rail Vehicles for the Green Line, at a per-LRV cost of $3,297,714 and a total contract value of $154,992,558. The LRVs were built in Florin, California, and the first vehicle was delivered on October 10, 2012. Safety and health impacts During testing of the Green line before it opened, there were four accidents recorded. One accident was at Portland Avenue
