Workers spent the day trying to get the tracks repaired to get train service back to normal as soon as possible, but that looks like it won't happen until at least Friday morning.
Today, fliers on the seats of their commuter trains urged them to participate in the railroad's annual Customer Satisfaction Survey.
Commuters have been left with longer rides aboard jam-packed trains.
The survey is routinely conducted at the end of May and the railroad spokesman says the timing is a coincidence.
"It's a management tool that we use to try to get better," said LIRR spokesman Joe Calderone. "It's not an idle exercise. We know people aren't happy this week."
Riders said the railroad officials should brace themselves for the results.
Customers are urged to check on LIRR service before heading to train stations by monitoring the MTA website, MTA.info, listening to the latest news broadcasts and traffic reports and/or signing up for free E-Alerts that provide the latest train information direct from the LIRR train operations center.
