I visited the site a few years ago but was a bit too late. The perimeter was fenced in and all of the buildings had been flattened. The track running east from the depot to a connection to an active railway had just recently been pulled up. A different track leaving the north side of the depot had been abandoned much earlier. A local fellow said the eastbound track hadn't been used in at least 20 years, if not longer.
According to a source I found, the depot had been used during WW II to provide service and repairs on equipment for units heading to the ports for deployment to Europe. Typically the personnel in the units were processed through Camp Kilmer, NJ, near Edison. According to "United States Army Transportation Corps Locomotives" by R. Tourret, GE-built US Army 7408, serial number 15726, built in 1942, provided motive power for the depot.
The site can be viewed in Google Earth, but there's little to see other than bare right-of-way and the concrete foundations of buildings that had once stood there. A topo map of the depot shows this:
