Two LIRR work trains collided Tuesday morning in Westbury, causing one to derail and injuring five people.
LIRR service is suspended in both directions between Mineola and Hicksville as authorities investigate. The MTA is running shuttle buses between Hicksville and Mineola.
The incident occurred just west of the Hicksville station shortly after 11 a.m.
Two train operators were taken to Nassau University Medical Center with minor injuries. The other three people injured were treated at the scene.
