The Green Line, operated by the MBTA, is a light rail system with an underground section in Boston. To replace the PCC cars that had been used for many years, the US Standard Light Rail Vehicle (USSLRV) manufactured by Boeing Vertol was introduced in 1976. However, problems frequently occurred in various parts such as the door, air conditioning ...
The MBTA's light rail vehicle types follow the nomenclature of the Boston Elevated Railway, which operated five series of cars. The numbering resumed with the unbuilt Type 6 prototype in the late 1960s, and continued with the custom-designed Type 7 and Type 8 of the 1980s and 1990s respectively.
The first low-floor light rail vehicle was delivered in 1996 [34] and first used in service on August 31, 1997. [33] The new vehicles also came equipped with air-conditioning, a feature originally lacking from the Type 1 vehicles. [31] The initial order of 39 Type 2 vehicles was expanded, in stages, to a total of 52 vehicles. [35]
The SLRV is a double-ended high-floor articulated light rail vehicle 71 ft (22 m) long overall (over the anticlimbers), in the same range as many heavy rail vehicles both at the time and now, but noticeably shorter than many other modern LRVs such as the at-minimum-81-foot (25 m) Siemens S70 and S700 commonly found today, which rides on three ...
Modern light rail technology has primarily German origins, since an attempt by Boeing Vertol to introduce a new American light rail vehicle was a technical failure. After World War II, the Germans retained their streetcar (Straßenbahn) networks and evolved them into model light rail systems . [5]
The P3010 is an articulated light rail car used on the Los Angeles Metro Rail system manufactured by Kinki Sharyo, operated on all of the Metro Rail light rail lines. [4] Ordered by Metro in 2012, the first train entered service in 2016. A total of 235 trains were built, making it Metro's largest rail fleet. [5]
In September 2013, 60 light rail vehicles were ordered, costing $200 million, for the Calgary CTrain; [5] the order was later slightly expanded to 63 LRVs at a cost of $201.6 million. [7] The first car was delivered on January 6, 2016. [8] Later, an additional 6 cars were ordered.
All of the concepts proposed a longer vehicle than the current Type 8/9 cars, with lengths ranging from 100 to 131 ft (30 to 40 m). The MBTA's final concept for the new cars was a 114-foot (35 m) articulated low-floor light rail vehicle made up of 7 segments, riding on 4 trucks, and equipped with 5 sliding doors on each side.
