This is a safety device, located near the end of the line Hoboken terminal, the final station stop on for two PATH lines. When a signal passed at danger condition occurs (when the train runs a red signal), the raised white bars perpendicular to the track cause the train's emergency brakes to activate. A nearby pneumatic compressor located on the platform can raise or lower the bars depending on the signal. (From A New York, A New Year)
