M Train (Manhattan Local)

The M Queens Boulevard/Sixth Avenue Local is a rapid transit service in the B Division of the New York City Subway. Its route emblem, or "bullet," is colored orange since it is part of the IND Sixth Avenue Line in Manhattan.

The M operates at all times. On weekdays from 6:00 a.m. to 9:00 p.m., it runs local between 71st Avenue in Forest Hills, Queens and Metropolitan Avenue in Middle Village, Queens. Weekend daytime and late evening weekday service is cut back to Essex Street on the Lower East Side of Manhattan, while late night service short turns at Myrtle Avenue–Broadway in Brooklyn.

The M is unique in that it travels through the same borough via two different, unconnected lines. It is also the only non-shuttle service with both of its full-run terminals in the same borough (Queens). Despite the full route length between 71st Avenue and Metropolitan Avenue being about 18.2 miles (29.3 km), the stations are geographically located just 2.47 miles (3.98 km) apart, making it the shortest geographic distance between termini for any New York City Subway service that is not a shuttle.
