Embattled Long Island Rail Road president Patrick Nowakowski – whose service has been besieged by consumer complaints – will resign his post this week, transit sources said Wednesday.

Nowakowski’s upcoming departure wasn’t considered a huge surprise, in the wake of an embarrassing state report last month that showed LIRR’s on-time performance in 2017 was the railroad’s worst in 18 years.

State Sen. Todd Kaminsky (D-Rockville Centre) welcomed the upcoming change in leadership.

“LIRR riders deserve a new leader who will demand immediate reform and who will level with and speak directly to them,” Kaminsky said, reacting to news of Nowakowski’s departure.

“Tough and no-nonsense leadership is needed urgently for one of the most important commuter rail systems in the country.”
