A post-Superstorm Sandy project to protect an Ocean County rail yard from future storms is underway.

New Jersey Transit says construction has begun on a project to harden its rail yard in Bay Head at the end of the North Jersey Coast rail line. The facility was flooded by storm surge from the ocean just a few blocks away during the 2012 storm.

The work includes a new power substation encased in protective materials and elevated above anticipated storm surge and flooding levels. The nearly $24 million project, funded by the Federal Transit Administration, replaces two existing Bay Head yard substations damaged during Sandy.
