Blue Line (MBTA)
Vorlage:Infobox rail line The Blue Line is one of the four subway lines of the Massachusetts Bay Transportation Authority. It extends from Wonderland station in Revere, Massachusetts in the northeast to Bowdoin station near Beacon Hill in Boston in the southwest. It meets the Green Line at Government Center, connects with the Orange Line at State station, and provides service to Airport station with a free shuttle connection to the various airline terminals. The line is designated Blue because for much of its length it uses the old Boston, Revere Beach & Lynn Railroad right-of-way along the seacoast in Revere and East Boston, and the tunnel to East Boston runs under the Atlantic Ocean.Vorlage:Fact Boston's Blue Line was the first subway in the world to run underneath a section of the ocean.Vorlage:Fact
Blue Line cars are unique among rapid transit vehicles in Boston in that they use both third rail and overhead pantograph current pickup. The line switches between the two at the Airport station where it transitions between running in a tunnel and running above ground. (The Silver Line waterfront switches between overhead and diesel power.) The overhead pantograph was implemented to avoid the third rail icing that frequently occurs in winter.
These cars are also shorter than otherwise similar ones running on the Orange Line, as the Blue Line (known as the East Boston Tunnel before the MBTA was formed) was initially designed to carry streetcars. The subway portion of the line was retrofitted with raised station platforms and rapid transit cars in the 1920s, with the surface portion between East Boston and Revere (known pre-MBTA as the Revere Extension) added in the 1950s.
As of 2005, there is a proposal to extend the Blue Line northward to Lynn, Massachusetts. The land to extend the line was purchased during initial construction, but due to budgetary constraints Wonderland station was designated the northern terminus. Two potential extension routes have been identified. One proposed path would run through marshland alongside the existing Newburyport/Rockport commuter rail line, on rail lines formerly operated by the Boston and Maine Railroad. An alternative route would extend the line alongside Revere Beach Boulevard through Point of Pines and the Lynnway, along the remainder of the BRB&L right of way.[1]
In addition, the MBTA has committed to designing an extension of the line's southern end west to Charles/MGH, where it would connect with the Red Line.[2] This was one of the mitigation measures the Commonwealth of Massachusetts agreed to as part of the Big Dig, originating from planning of the Boston Transportation Planning Review.
The Blue Line Modernization Program begun in the late 1990s includes renovating stations to increase the length of trains from four to six cars, make all stations wheelchair accessible, and improve cosmetic appearance. Bowdoin Station is likely to be closed due to the difficulty of accommodating 6-car trains inside the wedge-shaped track.Platform legnthening of Bowdoin is unlikely to occur. If platform length is increased to the west, expensive track re-organization must occur, and expanding to the east would make the station too close to Government Center Station. (Bowdoin is the western terminus, where inbound trains follow a tight loop to the outbound side.)

Accessibility
The Blue Line is accessible except for the most important stations: those downtown. Currently, the outbound Blue Line platform at State Street is wheelchair accessible to the street. Inbound wheelchair users can take the Blue Line to Government Center and cross the platform there to an outbound Blue Line train and take it to the accessible State Street platform. The MBTA has plans to make the remaining Blue Line stations accessible as part of a larger effort to permit 6 car trains on the line. See MBTA accessibility.
Equipment
The Blue Line is standard gauge[4] heavy rail. Its current fleet is the 0600 series, built 1978-1980 by Hawker Siddeley Canada Car and Foundry (now Bombardier Transportation) of Fort William, Ontario, Canada. They are 48.5 feet (14.8 meters) long and 111 inches (2.8 meters) wide, with two pairs of doors on each side. They are based on the PA3 model used by PATH in New Jersey. There are 70 Hawker cars, numbered 0600-0669.
The MBTA has ordered 94 new cars (47 pairs) with stainless steel bodies from Siemens Transportation Systems with dimensions identical to cars of the current fleet. The cars are of a similar design to those built for the Tren Urbano system in San Juan, Puerto Rico, also designed by Siemens. Originally scheduled to be delivered beginning in January, 2004, the development of the trains has been beset with development problems. The contract price of the cars is $174 million, with a total cost to the MBTA (including engineering and other related services) of $200 million. As of August 6, 2007, 10 of the 94 new cars, 702-703,704-705, 706-707, 708-709, and 710-711, have arrived and are now being tested at Wellington Station on the Orange Line and Orient Heights carhouse. 4 cars(704-705 and 702-703) are being tested on the Orange Line, making use of the unused express track between Wellington and Sullivan. Each car must be tested and run for at least 500 miles before it is allowed to be in service. The other cars will arrive by the Summer of 2008, when all 94 of the cars should be in service.
Trivia
The 1998 romantic comedy Next Stop Wonderland features some scenes from the Blue Line.
