Because of major temporary service changes to the LIRR line because of the recent series of accidents, I'd like to bring the MTA NYC Service Advisory Notification System to your attention. I have signed up for the service when it was still in beta, and while it doesn't prove terribly useful, it is still a good thing to have and to be made aware of.It says:
"Access to our email notification system sign up and options designation is temporarily unavailable until Tuesday Nov. 25th at 11:00 AM. This will allow us to migrate to a more robust email and text messaging alert system.
"Email Alert Notifications for existing customers will continue to be sent during this time period."
Hopefully, it'll be something much nicer than its current advisory iteration. Sign up here.
This NYTimes article talks about this updated service.
