Uniformed officers converged on the area to help keep traffic moving along Old Hook and nearby Schraalenburgh roads past the railroad crossing near the Oradell Reservoir.
One lane of Old Hook Road was closed.
Signs included: “Oil and water don’t mix” and “Ban unsafe trains now,” while demonstrators chanted: “Hey hey, ho ho, Bakken crude has got to go.”
The trains carrying the oil must cross a small, wooden bridge that spans the reservoir, which is full of drinking water for an estimated 750,000 customers in Bergen and Hudson counties.
