<P> However, due to construction on the Queens Boulevard Line, the G train frequently terminated at Court Square even at times when the published timetable said it ran to 71st Avenue . Some riders were suspicious that the service disruptions were "simply a de facto way to implement the original plan of halving G train service ." The original plans called for the G terminate at Court Square at all times; that plan was shelved in 2001 in the face of community opposition, but the MTA decided to implement it in 2010 . An MTA spokesman said, "It's not personal.... If you want to keep the system up to date, you need to make sure the track and switching are all in good repair ." </P> <P> Community groups such as Save the G! and the Riders Alliance have been frequent activists for improvements of G service . Save the G! regularly lobbied the MTA for more G train service since the original cutbacks when the V was introduced in 2001 . They made the restoration of service to the Queens Boulevard Line at all times an issue in the 2002 New York gubernatorial race, but the transit authority said, "Unfortunately, putting the G back to full service is just not an option, given our track capacity--and that's not likely to change ." </P> <P> To increase service and reduce waiting time due to the 63rd Street Connector cutbacks, the G would need more trains, but there were not enough cars available in the system . The solution was to reduce the length of trains in order to increase service frequency . Historically, the G line had run 8 60 - foot (18 m) car trains or 6 75 - foot (23 m) car trains; both were shorter than the typical 600 - foot (180 m) length of B Division trains because ridership was deemed too low to justify running full - length G trains in frequent intervals . Under the 2001 plan, trains were shortened from six 75 - foot (23 m) cars to four, sticking all the leftover cars together to make the extra trains for the G, and the additional trains needed for V service . Thus, G service now operates 300 - foot (91 m) trains, half the length of normal B Division standards . It also operates One Person Train Operation (OPTO) service during late nights and weekends . </P> <P> This, however, meant there would be more riders packed into smaller trains, and led some passengers to miss trains because they were standing at the wrong part of the platform . In the past, there have been signs indicating where the train stops at some stations, in addition to the "4" and "6" markers next to the tracks used by train operators as stop points . Still, the overall lack of visual identifiers of train stop points on the platforms, the differing stop points during different times of day, and the location of staircases, transfer passageways and platform benches have been cited as a cause of passengers missing trains or being bunched into single cars . Beginning in 2013, additional signs were installed along G train platforms . In 2014, several improvements were implemented due to an infusion of extra funding, with G trains to be lengthened in 2019 (see below). </P>

Why does the g train only have 4 cars
