Metro-North Railroad (NY) will test quiet cars on select peak hour trains on the Hudson and Harlem lines starting on October 17. The last car on certain morning peak trains and the first car on selected evening peak trains will be set aside for customers seeking a peaceful commute. The MTA expects the voluntary program to be self-enforcing, but conductors will issue “shh” cards if necessary. Metro-North will decide whether to expand the program based on customer reaction. A similar pilot conducted last summer in conjunction with NJ TRANSIT on the Port Jervis and Pascack Valley lines was well received and was recently expanded to all peak trains.
