51-440: The station consists of an island platform located in the center median of the elevated Interstate 580 . A fare lobby is located under the platform; a pedestrian and vehicle underpass connects the station to bus bays, parking lots, a parking garage, and surrounding development. The Iron Horse Regional Trail connects to both the north and south sides of the station. Service at the station began on May 10, 1997. Original plans in

102-797: A $ 30 million garage entirely on city-owned land and not subject to BART approval. The project will use $ 20 million in state funds awarded to the Livermore Amador Valley Transit Authority plus $ 10 million in local funds. A groundbreaking was held in October 2018. However, construction was delayed by the COVID-19 pandemic, and bidding did not take place until late 2021. Construction began in November 2022. The Tri-Valley-San Joaquin Valley Regional Rail Authority plans to construct

153-495: A Delta Express route from Antioch to West Dublin/Pleasanton station via Brentwood and Dublin/Pleasanton station from August 18, 2003, to February 24, 2012. Island platform An island platform (also center platform (American English) or centre platform (British English)) is a station layout arrangement where a single platform is positioned between two tracks within a railway station , tram stop or transitway interchange . Island platforms are sometimes used between

204-430: A bridge, a tunnel , or a level crossing . A variant on the side platform is the spanish solution which has platforms on both sides of a single through track. Modern station platforms can be constructed from a variety of materials such as glass-reinforced polymer , pre-cast concrete or expanded polystrene , depending on the underlying substructure. Most stations have their platforms numbered consecutively from 1;

255-412: A curved platform – often a platform gap is present. Usually such platforms will have warning signs, possibly auditory, such as London Underground 's famous phrase " Mind the gap ". There may be moveable gap filler sections within the platform, extending once the train has stopped and retracting after the doors have closed. The New York City Subway employs these at 14th Street–Union Square on

306-578: A developer between 2029 and 2033 for a second phase of TOD on the Pleasanton (south) side of the station, while additional TOD on the Dublin side would not begin until at least the mid-2030s. The construction of a second 665-space garage, promised by BART in 2002, proved controversial. A $ 37.1 million design was brought forward in February 2017; local officials were in favor of the garage – noting that existing parking

357-496: A few stations, including Cardiff Central , Haymarket , King's Cross , Stockport , and Gravesend (in the UK); and Lidcombe, Sydney (Australia), start from 0. At Bristol Temple Meads platforms 3 through to 12 are split along their length with odd numbered platforms facing north and east and even facing south and west, with a small signal halfway along the platform. Some, such as London Waterloo East , use letters instead of numbers (this

408-505: A guideline for platform safety specifies that for the platforms with train passing speeds between 160 kilometres per hour (99 mph) and 200 kilometres per hour (120 mph), there should be a yellow-line buffer zone of 1.5 metres (4.9 ft) and other warning signs. If trains can pass at speeds higher than 200 kilometres per hour (120 mph), the platforms should be inaccessible to passengers unless there are waiting rooms or screened areas to provide protection. The European Union has

459-632: A low floor serves a station built for trains with a high floor, for example at the Dutch stations of the DB Regionalbahn Westfalen (see Enschede ). On the London Underground some stations are served by both District line and Piccadilly line trains, and the Piccadilly trains have lower floors. A tram stop is often in the middle of the street; usually it has as a platform a refuge area of

510-587: 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

561-458: A rail line, Valley Link , running east from the station to serve Livermore and San Joaquin County . As the terminus of a BART line, Dublin/Pleasanton station serves as a local and intercity bus hub. A 10-bay bus plaza is located on the north side of the station; several more bus bays are located on the south side of the station. Two local bus providers use these bays for a number of routes that run in

612-410: A regulation for platforms that are close to tracks with train passing speeds of 250 kilometres per hour (160 mph) or more should not be accessible to passengers unless there is a lower speed limit for trains that intend to stop at the station or there are barriers to limit access. Platforms usually have some form of warnings or measures to keep passengers away from the tracks. The simplest measure

663-467: A significant safety problem as the safe distance from the platform edge increases with the speed of the passing train. A study done by the United States Department of Transportation in 1999 found that trains passing station platforms at speeds of 240 kilometres per hour (150 mph) can pose safety concerns to passengers on the platforms who are 2 metres (6.6 ft) away from the edge due to

714-409: A similar height to that of the sidewalk, e.g. 100 mm (4 in), and sometimes has no platform. The latter requires extra care by passengers and other traffic to avoid accidents. Both types of tram stops can be seen in the tram networks of Melbourne and Toronto . Sometimes a tram stop is served by ordinary trams with rather low floors and metro -like light rail vehicles with higher floors, and

765-457: 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 the tracks are above or below the entrance level, the station needs only one staircase and (if disabled accessibility

816-761: A train can arrive is referred to as a "track" (e.g. "The train is arriving on Track 5"). In other countries, such as the UK and Ireland, platform refers specifically to the place where the train stops, which means that in such a case island platforms are allocated two separate numbers, one for each side. Some countries are in the process of switching from platform to track numbers, i.e. the Czech Republic and Poland. In locations where track numbers are used an island platform would be described as one platform with two tracks. Many stations also have numbered tracks which are used only for through traffic and do not have platform access. Some of

867-470: A visually-contrasting color, for the full length of the platform. Ideally platforms should be straight or slightly convex , so that the guard (if any) can see the whole train when preparing to close the doors. Platforms that have great curvature have blind spots that create a safety hazard. Mirrors or closed-circuit cameras may be used in these cases to view the whole platform. Also passenger carriages are straight, so doors will not always open directly onto

918-522: 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 the station to serve as a point where slow trains can be passed by faster trains. A variation at some stations

969-609: Is at Hubballi Junction in India at 1,507 metres (4,944 ft). The Appalachian Trail station or Benson station in the United States, at the other extreme, has a platform which is only long enough for a single bench. Among some United States train conductors the word "platform" has entered usage as a verb meaning "to berth at a station", as in the announcement: "The last two cars of this train will not platform at East Rockaway". The most basic form of platform consists of an area at

1020-500: Is markings near the edge of the platform to demarcate the distance back that passengers should remain. Often a special tiled surface is used as well as a painted line, to help blind people using a walking aid, and help in preventing wheelchairs from rolling too near the platform edge. In the US, Americans with Disabilities Act of 1990 regulations require a detectable warning strip 24 inches (61 cm) wide, consisting of truncated dome bumps in

1071-489: 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 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

1122-406: 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 the local tracks (where the island would be). A common configuration in busy locations on high speed lines

1173-401: Is one at which the track terminates, i.e. a dead-end or siding . Trains serving a bay platform must reverse in or out. A side platform is the more usual type, alongside tracks where the train arrives from one end and leaves towards the other. An island platform has through platforms on both sides; it may be indented on one or both ends, with bay platforms. To reach an island platform there may be

1224-404: Is to distinguish the platforms from numbered ones in the adjoining Waterloo main-line station for staff who work at both stations); some, such as Paris-Gare de Lyon , use letters for one group of platforms but numbers for the other. The actual meaning of the word platform depends on country and language. In many countries, the word platform refers to the physical structure, while the place where

1275-718: 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 the IRT Seventh Avenue Line and 34th Street – Penn Station on

1326-724: 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

1377-662: The IND Eighth Avenue Line of the New York City Subway , uses two side platforms for local services with an island in between for express services. 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

1428-730: The Newport PATH station has the same configuration as Bowling Green—one side platform and one island platform. 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

1479-705: The Singapore MRT and the Hong Kong MTR , and stations on the Jubilee Line Extension in London. Platforms should be sloped upwards slightly towards the platform edge to prevent wheeled objects such as trolleys, prams and wheelchairs from rolling away and into the path of the train. Many platforms have a cavity underneath an overhanging edge so that people who may fall off the platform can seek shelter from incoming trains. In high-speed rail , passing trains are

1530-613: The Tri-Valley : Because I-580 is the primary highway from the Bay Area to the Central Valley , the station is the western terminus for several lengthy commuter-based routes from Central Valley cities. Those three routes, plus several daily Amtrak Thruway bus trips connecting with the San Joaquins train route, stop next to the parking garage north of the station. Tri-Delta Transit ran

1581-829: The Werribee Line , Ardeer , Caroline Springs on the Ballaarat Line , Glen Iris , Holmesglen , Jordanville and Syndal on the Glen Waverley Line , and Watsonia and Heidelberg on the Hurstbridge line . In Toronto , 29 subway stations use island platforms (a few in the newer stations on the Bloor–Danforth line , a few on the Yonge–University line and all of the Sheppard line ). In Edmonton , all 18 LRT stations on

1632-505: The aerodynamic effects created by pressure and induced airflow with speeds of 64 kilometres per hour (40 mph) to 95 kilometres per hour (59 mph) depending on the train body aerodynamic designs. Additionally, the airflow can cause debris to be blown out to the waiting passengers. If the passengers stand closer at 1 metre (3.3 ft), the risk increases with airflow that can reach speeds of 79 kilometres per hour (49 mph) to 116 kilometres per hour (72 mph). In United Kingdom,

1683-406: 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 the island platform is 6 metres (19 ft 8 in) wide, the tracks must slew out by the same distance. While this requirement

1734-630: The exception being Braddell MRT station , Bishan MRT station , and a few stations on the Downtown line ( Stevens , Downtown , Telok Ayer , Chinatown and MacPherson ) and the Thomson-East Coast line ( Napier , Maxwell , Shenton Way and Marina Bay ) In southern New Jersey and Philadelphia , PATCO uses island platforms in all of its 13 stations, to facilitate one-person train operation . The NYC Subway's Second Avenue Subway features island platforms at all stations. Many other stations in

1785-604: The late 1980s called for a station in West Dublin, with an East Dublin station near the Hacienda Business Park to be added later; however, by the early 1990s the order was reversed. The station was initially planned as East Dublin/Pleasanton during planning to differentiate it from the then-planned West Dublin/Pleasanton station (which ultimately opened in 2011). BART has referred to the station simply as Dublin/Pleasanton since opening, though WHEELS bus service refers to

1836-528: The late 1980s, with the unused side now facing onto a bus bay. Petone's island platform served the up main line and the suburban loop line until the suburban loop was lifted in the early 1990s. The unused platform now faces onto the station's park-and-ride carpark. Railway platform A railway platform is an area alongside a railway track providing convenient access to trains. Almost all stations have some form of platform, with larger stations having multiple platforms. The world's longest station platform

1887-532: The line to a larger gauge, by moving the track away from the platform to allow the wider bodied continental rolling stock to pass freely while leaving the platform area untouched. Island platforms are a very normal sight on Indian railway stations. Almost all railway stations in India consist of island platforms. In Sydney , on the Eastern Suburbs Railway and the Epping Chatswood Railway ,

1938-471: 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 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

1989-400: The next train. There are often loudspeakers as part of a public address (PA) system. The PA system is often used where dynamic timetables or electronic displays are not present. A variety of information is presented, including destinations and times (for all trains, or only the more important long-distance trains), delays, cancellations, platform changes, changes in routes and destinations,

2040-459: The number of carriages in the train and the location of first class or luggage compartments, and supplementary fee or reservation requirements. Some metro stations have platform screen doors between the platforms and the tracks. They provide more safety, and they allow the heating or air conditioning in the station to be separated from the ventilation in the tunnel, thus being more efficient and effective. They have been installed in most stations of

2091-471: 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 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

Dublin/Pleasanton station - Misplaced Pages Continue

2142-409: The same level as the track, usually resulting in a fairly large height difference between the platform and the train floor. This would often not be considered a true platform. The more traditional platform is elevated relative to the track but often lower than the train floor, although ideally they should be at the same level. Occasionally the platform is higher than the train floor, where a train with

2193-457: The station as East Dublin/Pleasanton. The station design features a "wave" design motif, most notably in the titanium canopy roof over the passenger platform, which has a silhouette of five curves intended to both echo the shape of the nearby hills in Dublin and "represent the sound waves generated by BART's electric propulsion." An adjacent transit-oriented development (TOD) on the Dublin side of

2244-528: The station facilities are often located on the platforms. Where the platforms are not adjacent to a station building, often some form of shelter or waiting room is provided, and employee cabins may also be present. The weather protection offered varies greatly, from little more than a roof with open sides, to a closed room with heating or air-conditioning. There may be benches , lighting , ticket counters, drinking fountains , shops, trash boxes, and static timetables or dynamic displays with information about

2295-494: The station with 240 residential units finished initial construction in 2006. The development included a 1,513-space BART parking garage, which opened on May 23, 2008. According to its architects, the "external design treatments ... draw the eye away from the height and size", but the San Francisco Chronicle's urban design critic John King dismissed the result as "cartoonishly clumsy." As of 2024, BART anticipates soliciting

2346-494: The system have the same layout. Sometimes when the track on one side of the platform is unused by passenger trains, that side may be fenced off. 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,

2397-522: 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 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

2448-583: The tram stop has a dual-height platform. A railway station may be served by heavy-rail and light-rail vehicles with lower floors and have a dual- height platform, as on the RijnGouweLijn in the Netherlands. In all cases the platform must accommodate the loading gauge and conform to the structure gauge of the system. Platform types include the bay platform , side platform (also called through platform), split platform and island platform . A bay platform

2499-573: 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

2550-473: Was full by 7:45am on weekdays – but the BART Board rejected it because of cost concerns and a 2016 BART policy to prioritize non-auto access to stations. The Board instead approved a $ 17.2 million "hybrid" model that included restriping existing parking, improving bus service and Iron Horse Regional Trail connections, and installation of an automated parking system . In May 2018, local officials announced plans for

2601-541: Was renovated to accommodate the high volume of passengers coming to the 1939 World's Fair . Many of the stations on the Great Central Railway in England (now almost entirely closed) were constructed in this form. This was because the line was planned to connect to a Channel Tunnel . If this happened, the lines would need to be compatible with continental loading gauge , and this would mean it would be easy to change
