HOBOKEN - PATH service is suspended along the 33rd Street line for a federally mandated safety addition.

The PATH will be shut down every weekend until Dec. 19 for safety upgrades.

Crews are installing an emergency braking system called Positive Train Control, designed to decrease collisions and derailments.

Alternatives for riders are available, including the IS PATH service which takes riders from New Jersey to the World Trade Center from both Hoboken and Newark.

Commuters are also encouraged to take the ferry.

Normal service will resume after each weekend beginning on Mondays at 5 a.m.
