Due to either a sick passenger or signal problems, the announcements were inaudible, riders waited for more than 25 minutes, between 7:40 and 8:10am (that we spoke to), on the platform at Roosevelt Island before the mass exodus began out of the station. My family included.
Riders quickly walked to a growing Tram line which stretched back to the kiosk by approximately 8:15 am. It is unknown what the true problem was and when and if it has cleared up. No service advisory was received via email from the MTA at this time.
Thankfully the Tram is not scheduled to go off line for about 6 weeks.
