Subway riders have less than a 50 percent chance of hearing what's going on when their train stops in the tunnel or gets diverted, according to a new study by the advocacy group the Straphangers Campaign. Cate Contino, the coordinator of the group, says that is when announcements are most crucial.
Over the course of five months in 2009, her group observed 121 subway diversions on 22 different lines and in 67 cases they heard either no announcement or what they heard was garbled or inaudible.
The study did find that 82 percent of basic announcements are clear and audible -- a slight improvement from the last time results were released.
The group says the worst lines were the D, G, and No. 7, where just 62 percent of basic announcements made the grade.
MTA guidelines stipulate that conductors are supposed to give a specific reason for a delay every two minutes when a train is stopped.
