75-548: D2 Subway is a proposed 2.4 miles (3.9 km) expansion of the DART light rail system in metropolitan Dallas , Texas, in the United States. The subway would run from the existing Victory station , tunneling underground through the city centre of downtown Dallas, and connect to the existing tunnel under Cityplace . Four new stations would be built along the new alignment. The Green Line and Orange Line would have routed through
150-583: A junction from the existing Green and Orange Line alignment, and traveling at-grade in a southeasterly direction within DART-owned right-of-way in the center of Museum Way crossing Victory Avenue, Victory Park Lane, and Houston Street. The alignment would continue through a parking lot directly south of the Northend Apartments and used by patrons and visitors of the Perot Museum of Nature and Science where
225-401: A bridge or underpass. If an island platform is not wide enough to cope with passenger numbers, typically as they increase, overcrowding can risk people being pushed onto the tracks. In some cases entry to the station is restricted at busier times to reduce risk. Examples of stations where a narrow island platform has caused safety issues include Clapham Common and Angel (rebuilt in 1992) on
300-506: A majority of their routes. A decision was intended to be made by 2018 as to which route will be pitched to the FTA, although city leaders in 2017 had endorsed the Commerce subway route (along with a downtown streetcar design) to move forward into consideration. A preferred alignment was chosen by DART and the city of Dallas in 2022; all stakeholders in the project agreed on this preferred alternative for
375-587: A new side platform opening in December 2022. Some stations of the Glasgow Subway have one island platform and one side platform ( Hillhead , Buchanan Street , and Ibrox ). In Wellington , New Zealand, unused sides can be found at two stations on the Hutt Valley Line : Waterloo and Petone . Waterloo's island platform was reconfigured to be the down side platform when the station was extensively rebuilt in
450-428: A northeasterly direction before surfacing near the portal of the existing light rail tunnel under Cityplace . The project would include four new DART stations: one at-grade, and three underground which would consist of center platforms and introduce fare barriers. From west to east, the stations are: The project would shift Blue and Orange Line service from the existing Pacific Avenue and Bryan Avenue transit mall to
525-600: A possibility of four-car trains with the LRV type vehicles of the time. The newer SRLV have that length with three-car trains already. The raised and underground stations had been constructed at 400 feet (120 m) from the beginning but it is a higher effort to rebuild them to a raised platform in the first phase due to existing stairs. The Blue Line runs from southwest to northeast, UNT Dallas , in southwest Dallas, to Downtown Rowlett Station in Rowlett . Heading north from UNT Dallas,
600-399: A raised boarding area of 385 feet (117 m). At each end crossings and ramps are built. The Orange and Green Lines had been constructed to that standard from the beginning. However they could not use that length in regular operation. The platform extensions were part of the initial planning of system with reserved space on each station since the 1980s. However, this concept was expecting
675-466: A route from downtown Dallas southeast to Fair Park ; this short route was scheduled to open in time to service the 2009 State Fair of Texas . On December 6, 2010, the line extended further at both ends – to Pleasant Grove , as well as continuing northwest from Victory Station to Farmers Branch and Carrollton ; both extensions, completing the Green Line. The Green Line's northern end connects with
750-540: A second downtown light rail alignment date back to DART's 1983 Service Plan to accommodate the interlining of multiple future corridors in the DART Service Area. This plan laid the groundwork for a goal of three potential corridors with a goal that the initial development focus on an east to west subway rather than an at-grade transit-way mall if funding allowed. However, after a failed bond vote in June 1988, DART's System Plan
825-461: A stop in the middle at Medical/Market Center Station . The agency had to lease rail cars due to a delay in the current stock until that March. After the success of the light rail starter system, voters approved DART's request to use long-term bonds to expedite the construction of the regional light rail system. While DART had originally planned single-track extensions of the Blue Line to Garland and

Island platforms are sometimes used between the opposite-direction tracks on twin-track route stations as they are cheaper and occupy less area than other arrangements. They are also useful within larger stations, where local and express services for
1050-589: Is expected for 2022. In March 2018 the contract was awarded to Lockwood, Andrews & Newnam (LAN). Construction started in July 2019 to be finished in August 2022. Apart from capacity the project allows for barrier-free access to trains even on the oldest lines of the network. The platforms will be raised to the 15.5 inches (40 cm) floor height of the low-floor middle section of the SLRV trains. This concept allows to get half of
1125-747: The A-train line run by the Denton County Transportation Authority (DCTA). This line connects Denton to Carrollton , with stops in Lewisville and Highland Village . The commuter train may stop in other Denton County cities, should they choose to join the DCTA. The second line, the Orange Line originates at LBJ/Central on the Red Line and runs concurrently with the Red Line to downtown, then with
1200-554: The Blue Line from Pearl Street to Morrell Station and Illinois Avenue . The next stage of the starter line opened on January 10, 1997 when the Red Line was extended from Pearl Station to Park Lane Station . It includes the tunnel from Pearl Street to Mockingbird Lane , the latter being the site of Dallas's first modern transit village . The northern terminus of the Blue Line remained Pearl Station at that time. The starter line
1275-573: The Blue Line was extended from Mockingbird Station to the new White Rock . Later, the Blue Line was further extended east outside the LBJ Loop when the LBJ/Skillman Station opened on May 6, 2002. The first extension of the Red Line opened on July 1, 2002, when the line was extended 7 stations north from a newly rebuilt Park Lane Station to Galatyn Parkway . Richardson became the first Dallas suburb to be served by light rail. The Blue Line
1350-517: The Blue Line , the Red Line , the Green Line , and the Orange Line . In 2023, the system had a ridership of 21,380,900, or about 63,200 per weekday as of the third quarter of 2024. That makes it the 6th highest ridership of light rail systems in the United States ; however, it was one of the worst financial performers. The system uses the Kinki Sharyo SLRV ("Super Light Rail Vehicle") and
1425-724: The Capital Line and Metro Line used island platforms until NAIT/Blatchford Market station opened in 2024, the only station with side platforms as of 2024. The Valley Line Southeast uses low-floor LRT technology, but uses island platforms on only one of the 12 stops, Mill Woods . Almost all of the elevated stations in Singapore 's Mass Rapid Transit (MRT) system use island platforms. The exceptions are Dover MRT station and Canberra MRT station , which use side platforms as they are built on an existing rail line, also known as an infill station . The same follows for underground stations, with
1500-594: The Dallas Central Business District corridor, and the Orange and Green Lines also using this trunk segment through downtown, a single alignment would not have the capacity to support all four rail lines. Under a 1990 agreement with the City of Dallas, DART agreed to build a second rail alignment through downtown once certain operating or ridership figures were met, and DART projected that it would hit these targets by

The purpose of this atypical design was to reduce unnecessary passenger congestion at a station with a high volume of passengers. Since the IRT Seventh Avenue Line and IND Eighth Avenue Line have adjacent express stations at 42nd Street, passengers can make their transfers from local to express trains there, leaving more space available for passengers utilizing intercity rail at Pennsylvania Station . The Willets Point Boulevard station

The Orange Line runs between Parker Road station in Plano and Dallas/Fort Worth International Airport . The Orange Line duplicates
1800-629: The London Underground , Union (rebuilt in 2014) on the Toronto subway , and Umeda on the Osaka Municipal Subway . An island platform requires the tracks to diverge around the centre platform, and extra width is required along the right-of-way on each approach to the station, especially on high-speed lines. Track centres vary for rail systems throughout the world but are normally 3 to 5 metres (9 ft 10 in to 16 ft 5 in). If

On the Tokyo Metro , the Ginza Line has a side platform and an island platform at Nihombashi . Likewise, the Namba and Minami-morimachi stations on the Osaka Metro have similar configurations. On JR East, the Yokosuka Line platforms at Musashi-Kosugi feature a similar setup following

The first Orange Line stations opened on July 30, 2012, while service to Belt Line Station in Irving began on December 3, 2012. An extension of the Orange Line from Belt Line Station to DFW Airport Station opened on August 18, 2014. In 2007, DART recognized that with Blue and Red Line trains sharing tracks through
2025-531: The Red Line from Forest Lane Station to the Addison Transit Center , which would have included several miles of subway under Interstate 635 . DART officials cited the line's high cost, US$ 700 million, and lack of strong support from the city of Dallas. The Blue Line extension to the Dallas Southport Center (intermodal terminal) was added after strong pressure from Dallas officials. Also,
2100-659: The Tower at Cityplace skyscraper, providing access to the Tower as well as Cityplace West. It was the system's first in-fill stop. Commuter rail on the old Rock Island right-of-way began during the series of openings of the light rail starter system. On December 30, 1996, the Trinity Railway Express opened the first segment as the South Irving Transit Center was connected to Union Station in downtown Dallas with

In August 2015, the Dallas City Council voted to only recommend an alignment above-ground along Jackson Street, over the objections of DART officials, who requested the addition of a Young Street route as a fallback. The alignment along Young Street was opposed by the First Presbyterian Church of Dallas , as

The group lobbied for electric light rail vehicles on the line to avoid perceived air and noise pollution associated with diesel rail, and also proposed that the line be placed in a below-ground trench. These proposals were accepted by the City of Dallas in June 2006 in a unanimous resolution. DART, however, balked at the cost of trenching

2400-461: The D2 Subway alignment, thereby alleviating pressure along DART's Pacific Avenue and Bryan Avenue corridor, which all four lines currently share, and promoting system-wide growth in total capacity. The project was estimated to cost between $ 1.7 and $ 1.9 billion. In 2023, DART removed the D2 Subway from its long-term financial plan, effectively indefinitely delaying the project. Proposals for
2475-504: The D2 Subway corridor, with the Orange Line maintaining its current terminals. The Red and Green Lines would continue to operate on the existing transit mall. Additionally, the western segments of the Blue and Green Lines would swap alignments, with the Green Line terminating at UNT Dallas and the Blue Line running to North Carrollton/Frankford . The system would continue to operate at 15-minute peak headways and 20-minute off-peak headways and with
2550-511: The D2 alignment would be used for Green and Orange Line service while the Red and Blue Lines would continue to use the existing alignment. However, on April 27, 2010, DART announced financial problems would prevent it from funding construction of the D2 alignment, putting the plan in limbo. After a three-year hiatus, DART announced on February 6, 2013 that it would begin holding public hearings on "Phase II" of
2625-464: The D2 study, to discuss alternatives and refinements to its D2 options since it ended "Phase I" of the D2 study in 2010. At a public hearing on February 13, 2013, DART announced it was expanding to consider eight possible D2 alignments, some of which would connect to Union Station instead of Victory Station and thus provide Red and Blue Line service. While the D2 Study is being funded by a $ 700,000 grant,
2700-615: The Federal Transit Administration (FTA) approved a US$ 700 million Full Funding Grant Agreement (FFGA) — the largest grant ever awarded to DART — to kick-start a US$ 2.5 billion expansion of the light rail system. This phase included two new light rail lines that doubled DART's light rail mileage. Construction began in September 2006. Upon completion of the project in 2013, the size of DART's light rail system doubled to 90 miles (145 km). In maps before 2006, DART labeled
2775-464: The Green Line to northwest of Love Field Airport at Bachman Lake , where it branches off toward Irving , then continuing to DFW International Airport . DART is cooperating with Love Field to link that airport to the Orange Line, but service is currently connected by a bus shuttle. The line runs through Las Colinas and connects to the Las Colinas APT System . DART had preliminary plans for
2850-508: The Pleasant Grove to Carrollton route the "Orange Line", and the Irving route was the "Purple Line". Green was generally used on DART maps to denote the route of the Trinity Railway Express . By the time construction started, DART was using the new Green Line designation as part of its marketing efforts, saying "Like the color green, this line is a symbol of our city on the move." The Green Line began operation on September 14, 2009, with
2925-597: The Red Line along the Central Expressway ( US 75 ) corridor from Parker Road to the Dallas Central Business District , then follows the Green Line along the Interstate 35E (Texas) corridor, serving the American Airlines Center , Parkland Hospital , and Love Field , before branching west along the Highway ;114 corridor to Irving . The final leg of the Orange Line from Belt Line to DFW Airport opened on August 18, 2014. The DART system operates seven days
3000-440: The Red Line to Richardson and Plano , the starter system was so popular that the agency made plans to double-track the entire route. Work began on the extensions of both the Blue Line and the Red Line on January 15, 1999. Later that same year, on September 27, the Blue Line designation was extended to Mockingbird Lane, for its eventual expansion to Garland. The first station since 1997 to open came on September 24, 2001, when

While under Commerce Street, a second underground station, Commerce Street station, would be located between Akard Street and Ervay Street. Before passing under South Pearl Street, the alignment would begin to turn northeast, crossing diagonally underneath existing buildings and structures. A third underground station, CBD East station, located between Main Street and Elm Street would provide access for transfers to additional buses at DART's East Transfer Center . The alignment would continue traveling in

3150-556: The alignment to be in a subway for the majority of its time in downtown. This led DART to have to reconsider the alignment, and also balance funding for the Silver Line , which created tension between supporters of both rail lines, who believed that only one of the two could be built. However, DART eventually voted in favor of eventually funding the Cotton Belt and D2. DART is considering three alignments, all of which are underground for
3225-724: The at-grade, Museum Way station, would be located. Upon leaving the station, the alignment would cross under Spur 366/Woodall Rodgers Freeway and after crossing McKinney Avenue, located on the other side of the highway, the alignment would begin its transition underground through the "west tunnel portal", passing under Hord Street near the Dallas World Aquarium and remaining underground for its duration. The alignment continues south under Griffin Street and between San Jacinto Avenue and Elm Street, an underground station, Metro Center station, would be located providing access for transfers to buses at DART's West Transfer Center or access to
3300-510: The commuter rail line would run to the nearby Bush Turnpike station, the nearest station to the south of downtown Plano. The Cotton Belt line would run through former DART member city Coppell between Carrollton and DFW Airport; although no station locations are included in the plan, the promise of a future station could entice Coppell, which withdrew from DART in 1989, into rejoining the agency. In 2010, citing deficits and drops in revenue, DART scrapped much of their 2030 plan. On July 3, 2006,

DART light rail The DART light rail system serves the metropolitan area of Dallas , Texas . It is owned and operated by Dallas Area Rapid Transit (DART). The system opened June 14, 1996 and serves 65 stations and four lines, covering 93 miles (149.7 km):
3450-587: The current station. In 2021 DART reconfigured the project's eastern approach to continue into the existing Cityplace/Uptown station tunnel , foregoing the planned surface junction near Deep Ellum. In February 2022, the Dallas City Council and DART Board of Directors each approved this new alignment. In 2023, the project was removed from DART's twenty-year financial plan, citing high project costs, shifting priorities, and low post-pandemic ridership. The project would begin south of Victory Station, diverting via
3525-494: The early 2010s. As a result, DART commissioned its Downtown Dallas Transit Study, known as the D2 Study , to study the possibility of building a second rail alignment through downtown. In spring 2008, DART announced it had considered 16 possible plans for a second rail alignment, and selected four for more detailed consideration. All four proposals provided for an alignment between Victory Station and Deep Ellum Station , indicating

3750-439: The first time in the project's history. The D2 subway project was quietly removed from DART's long-term financial plan in July 2023. DART will instead use debt capacity intended for the D2 subway to improve the current system, including new trains, signal upgrades, and reliability and cleanliness improvements. The agency intends to explore alternatives to increase capacity in downtown Dallas and methods to increase ridership across
3825-457: The first time, and completing the current configuration of the Red Line. In October 2006, the DART Board of Directors unanimously approved a long-term "2030 Plan", which included the following proposals for its next round of rail expansion: The final 2030 plan included several changes from the draft plan released in July 2006. Removed from the final plan was a 6.3-mile (10.1 km) branch of

#17328690859243900-482: The fleet of 163 vehicles was modified in the 2000s to add level boarding and higher passenger capacity. The following lines are active: DART's initial plans called for 160 miles (257.5 km) of commuter rail. The election plan was pared down to 147 miles (236.6 km) when Duncanville , Grand Prairie and Mesquite , which would have had rail lines, opted out of joining the agency. DART chose light rail transit as its primary mode of rail transportation. The plan
3975-585: The funding from the Teax Mobility Funds. Almost another half of the funding comes from federal resources leaving mostly the planning costs to DART, which is below ten million. The project has accordingly two phases. In the first phase the platforms are raised by 7.5 inches (20 cm) on their existing length. In the second phase the platforms are extended from their original 300 feet (91 m) to accommodate long trains. A common street-level station will have side platforms of 450 feet (140 m) length with
4050-428: The island platform is 6 metres (19 ft 8 in) wide, the tracks must slew out by the same distance. While this requirement is not a problem on a new line under construction, it makes building a new station on an existing line impossible without altering the tracks. A single island platform also makes it quite difficult to have through tracks (used by trains that do not stop at that station), which are usually between
4125-493: The light rail system began service on time and on budget inaugurating the first light rail system in Texas . Commuter rail service to Irving began in December, after some delays. To the surprise of critics, the new light rail system was embraced by Dallasites, with ridership exceeding expectations. The suburbs' confidence in DART was also expressed at the ballot box: four cities held highly publicized pullout elections in 1996 (with
4200-463: The light rail would run through its property. However, the church and local residents, along with structural issues (the local library would have to be demolished, and many historic buildings would be close to or within the path of the line), helped to form an opposition to the new Jackson locally preferred alternative (LPA). Due to this, the City of Dallas voted against the Jackson alignment and instead for

The final plan compromised by promising $ 50 million "to help address neighborhood concerns". The current Cotton Belt freight corridor runs just south of the Downtown Plano station on the Red Line , but DART maps of the 2030 plan indicated that
4500-472: The local tracks (where the island would be). A common configuration in busy locations on high speed lines is a pair of island platforms, with slower trains diverging from the main line (or using a separate level on the railway's right-of-way ) so that the main line tracks remain straight. High-speed trains can therefore pass straight through the station, while slow trains pass around the platforms (such as at Kent House in London ). This arrangement also allows
4575-533: The platform without walking across the tracks. Island platforms are necessary for any station with many through platforms. There are also advantages to building small two-track stations with a single island platform instead of two side platforms. Island platforms allow facilities such as shops, toilets and waiting rooms to be shared between both tracks rather than being duplicated or present only on one side. An island platform makes it easier for disabled travellers to change services between tracks or access facilities. If
SECTION 60
#17328690859244650-441: The proposed light rail line serving West Dallas was not originally considered as a priority for rail service. The Cotton Belt corridor plans continued to generate controversy right up to the day of the vote on the 2030 plan. DART leaned toward diesel powered commuter rail for the Cotton Belt corridor, similar to the Trinity Railway Express . However, the line would pass through affluent Far North Dallas neighborhoods, which formed
4725-485: The same direction of travel can be accessed from opposite sides of the same platform instead of side platforms on either side of the tracks, simplifying and speeding transfers between the two tracks. The historical use of island platforms depends greatly upon the location. In the United Kingdom the use of island platforms on twin-track routes is relatively common when the railway line is in a cutting or raised on an embankment , as this makes it easier to provide access to
4800-409: The same span of service from approximately 3:30 AM to 1:30 AM. Based on core capacity needs, additional Red Line service would be added during peak hours from Cedars station to Parker Road station to address crowding. Services would continue to operate with two- or three-car length trains and not require an additional increases in fleet size beyond the current 163 Kinki Sharyo SLRV cars. Trains on

A variation at some stations is to have the slow and fast pairs of tracks each served by island platforms (as is common on the New York City Subway ; the Broad Street Line of Philadelphia ; and the Chicago Transit Authority 's Red and Purple lines). A rarer layout, present at Mets-Willets Point on the IRT Flushing Line , 34th Street – Penn Station on

Examples include Hurlstone Park , Lewisham, Sydney and Yeronga, Brisbane . In New York City's subway system , unused sides are located at Bowling Green as well as every express station without express service, such as Pelham Parkway on the IRT Dyre Avenue line. In Jersey City,
5100-432: The system. To allow for more capacity the "platform extensions" will be completed before tunneling on the D2 corridor starts. This project allows for three-car trains during rush hour. There are 28 stations on the red and blue line that will be rebuilt at an estimated cost of $ 129 million. The planning for the platform extensions started in 2014 and the construction was approved in 2017. Regular operation of three-car trains
5175-434: The tracks are above or below the entrance level, the station needs only one staircase and (if disabled accessibility is necessary) one elevator or ramp to allow access to the platforms. If the tracks are at the same level as the entrance, this instead creates a disadvantage; a side platform arrangement allows one platform to be adjacent to the entrance, whereas an island platform arrangement requires both tracks to be accessed by
5250-417: The twin tunnels are widely spaced and the tracks can remain at a constant track centres while still leaving room for the island platforms. A slight disadvantage is that crossovers have to be rather long. Examples in Melbourne include West Footscray , Middle Footscray , Albion and Tottenham on the Sunbury line , Kananook on the Frankston Line , Aircraft , Williams Landing and Hoppers Crossing on
