Military Park Station (formerly Broad Street Station) is an underground station on the Newark City Subway Line of the Newark Light Rail.  The station is owned and service is operated by New Jersey Transit.  The station is located at the intersection of Raymond Boulevard, Park Place and Broad Street in Downtown Newark at Military Park.  The station was opened in 1935 and called Broad Street Station.  It was renamed so only one station in the system would carry the name Broad Street when Downtown Newark's stations (Penn Station and Broad Street) were connected by the Newark Light Rail Line.  The station is decorated with beige tiles and colored tiles for borders, mosaics and street indicator signs.  This station is not wheelchair accessible, but the adjacent stations, Penn Station and Washington Street, are. Nanuet is a train station in Nanuet, New York, serving Metro-North Railroad and New Jersey Transit trains on the Pascack Valley Line.  Its official address is 1 Prospect Street, but in reality, it is located on Orchard Street West, diagonally off the southwest corner of Prospect Street and Middletown Road.  This line runs north-south to Hoboken Terminal with connections via the Secaucus Junction transfer station to New Jersey Transit one-stop service to New York Penn Station and to other New Jersey Transit rail service.  Connections are available at the Hoboken Terminal to other New Jersey Transit rail lines, the PATH train at the Hoboken, New York Waterways ferry service to the World Financial Center and other destinations, and Hudson-Bergen Light Rail service. The Downtown Seattle Transit Tunnel (DSTT), also referred to as the Metro Bus Tunnel, is a 1.3 mi pair of public transit tunnels in Seattle, Washington, United States.  The tunnel serves Downtown Seattle, running west under Pine Street from 9th Avenue to 3rd Avenue, and south under 3rd Avenue to South Jackson Street.  It was used only by buses from its opening in 1990 until 2005, and since 2009 it has been shared by buses and light rail.  The double-track tunnel and its stations, except Convention Place, constitute parts of the Central Link light rail line, which continues north to the University of Washington station and south through the Rainier Valley to Seattle–Tacoma International Airport as part of Sound Transit's Link light rail network.  Its five stations are also served by King County Metro and Sound Transit Express buses that leave the tunnel north via Interstate 5, south via the SODO Busway, or east via Interstate 90.  The DSTT is the busiest section of the Link light rail network, with an average of over 10,000 weekday boardings.  It is owned by King County Metro and shared with Sound Transit through a joint-operating agreement signed in 2002.  The Downtown Seattle Transit Tunnel is one of two tunnels in the United States shared by buses and trains, the other being the Mount Washington Transit Tunnel in Pittsburgh, and is the only one in the United States with shared stations. Bergenline Avenue is a major commercial district in the North Hudson section of Hudson County, New Jersey, United States.  The north-south streets passes through Union City, West New York, Guttenberg, North Bergen.  Its southern end is at Union City's Second Street, the north boundary of Washington Park.  From there north to 47th Street, the street is one-way southbound; New York Avenue and Kennedy Boulevard serve northbound traffic.  Between 48th and 49th Streets, elevators on the west side provide access to the underground Bergenline Avenue station of the Hudson-Bergen Light Rail.  After passing through West New York and Guttenberg and into North Bergen, the street meets North Hudson Park, running along its west side from 79th Street to the Bergen County line through the community of Nungesser's and crosses Kennedy Boulevard.  The northernmost 0.04 mi of the route from Kennedy Boulevard to the Bergen County line is designated as County Route 721.  North of the county line the street name becomes Anderson Avenue, which is the major commercial district for Fairview, Cliffside Park, and Fort Lee. BayLink is a long proposed transit connection between Miami and Miami Beach, Florida.  Proposals have ranged from streetcar, light rail, monorail, Metromover, or Metrorail extension that would connect Downtown Miami to South Beach via the MacArthur Causeway, with the light rail or streetcar options potentially having loops at both ends.  Originally proposed as an elevated light rail line such as a monorail, Miami Beach city officials opposed this in favor of something less intrusive, such as a streetcar.  Historically, Miami Beach has also cited concerns of unwanted downtown residents as a detriment to the South Beach image.  Additionally, the unused parts of the bases of the MacArthur Causeway bridge pilings that were to be used to support the line have been used for the widening of the causeway for the construction of the Port Miami Tunnel, complicating a fully separated right of way.  Officials still thought it was feasible as a light rail streetcar, and in 2014 were considering the possibility of a public-private partnership to help fund it.  In 2015, the cities of Miami and Miami Beach decided to break the estimated $532 million system into three pieces; two compatible light rail loops in Downtown Miami and South Beach to later be connected via MacArthur Causeway.  This was motivated by the lengthy federal studies required for a larger project.  French transport vehicle manufacturer Alstom gave an unsolicited proposal to build the Miami Beach portion of the system for US$148 million as a wireless streetcar system from 5th Street to Dade Boulevard via Washington Avenue.  Alstom predicts over 20,000 riders a day just on the eight to ten stations that would be on the Miami Beach segment. 9th Street–Congress Street is a station on the Hudson–Bergen Light Rail (HBLR) operated by New Jersey Transit which opened on September 7, 2004.

Hamburg Street station is a Baltimore Light Rail station in Baltimore, Maryland.  The station is located south of Camden Yards, adjacent to M&T Bank Stadium.  The station did not exist when the light rail began operation in 1992.  It was built in 1998 as an infill following the construction of the stadium.  At that time, since portions of the light rail line had only one track, thereby forcing trains to run on a tight schedule, the stop was used only for stadium events and bypassed at all other times.  But in 2005, when the south end of the light rail was double-tracked, the Hamburg Street stop was converted into full-time usage. 9th Street station is a light rail station for the future LYNX Blue Line in Center City Charlotte, North Carolina, United States.

St. Rose of Lima Park is a split Sacramento RT Light Rail station, located near the park named in honor of Rose of Lima, in Downtown Sacramento, California.  From the RT light rail's inception in 1987, it consisted of only two platforms at the vicinity: the northbound one (towards Watt/I-80) at the intersection of 9th and K Streets, and the former southbound one at 7th and K Streets.  When RT expanded the light rail system in 2007 to serve Sacramento Valley station, it added the northbound-only 8th and K Streets station.  Today, the 9th street platform is marked as "St. Rose of Lima Park" while the platform in the middle on 8th Street is simply marked as "8th and K".
