The New York Straphangers Campaign on Wednesday released its annual "State of the Subways Report Card" and rated the number 7 the best of the city's 19 subway lines.
The 7 jumped ahead of other lines in the survey, thanks to how many trains run on the line.
Other factors include subway car cleanliness, the amount of available seating during rush hour, and the lack of delays caused by mechanical breakdowns.
On the flipside, the number 2 train ranked the worst.
That line was marked down for poor service, frequent delays and lack of rush hour seating.
