New York City riders gave the No. 7 subway line a pass grade for overall performance in a Metropolitan Transit Authority (MTA) survey released Thursday.
The 16,000 riders, who filled out rider report cards last month, gave the line, on average, a C-.
The subway line was graded on 21 different areas of service like on-time arrivals, lack of graffiti in stations and easy use of turnstiles.
Scoring lowest was adequacy of room onboard at rush hour, which got a D.
Transit officials said they had already run the maximum number of trains possible during rush hour, but hoped to start adding trains around the edges of rush hour sometime this winter.
The highest grade No. 7 line riders gave was for availability of Metrocard machines, a B- in that category.
MTA officials handed out more than 88,000 surveys during morning rush hour, and riders could respond via mail or online in 13 different languages. Nearly 16,000 questionnaires were returned, most by mail and about 4,000 online.
The survey was the first customer report card issued by the MTA, and transit officials are currently accepting responses from customers who ride the L, J and Z trains.
Based on the results, MTA officials will develop improvement plans, which will be reviewed by New York City Transit President Howard Roberts.
About six months from now, riders on the No. 7 train will be surveyed again to see there is any improvement.
