On August 20th, 2025, New Jersey Transit’s self-propelled Track Geometry Inspection Vehicle (TGIV) lays over on the Piermont Branch (Suffern Industrial) adjacent to the former Erie Railroad depot at Suffern, New York. Built by Harsco Rail, the TGIV continuously measures track geometry and catenary conditions using an array of non-contact sensors at speeds up to 50 mph. The data gathered provides NJ Transit engineering teams with a detailed view of track condition, supporting proactive maintenance and long-term infrastructure planning.
