Thanks for catching my mistake. You are quite right in that I was referring to CR 547 in front of Lakehurst Naval Air Engineering Station (NAES).
To get a much better and thorough history of the area and see some excellent pictures of the trackage in use, I highly recommend the web site http://octrainguy.com
. OCTrainguy is also a member of the RR.Net and I will quickly deferr to his knowledge of the area.
The grade crossings over St Hwy 88, CR527, CR528, CR571, and under St Hwy 70 all belong to the Southern Secondary (connecting to the NJCL at Red Bank). You can find several threads discussing the action (drilled by SA31) on RR.net. The main legacy of course was that this was part of the famous route of the CRRNJ Blue Comet on its run down to Atlantic City. The Southern Secondary fed Lakehurst NAES and Earle Naval Weapon Station (NWS).
Ft. Dix was fed by the Pemberton and Hightstown RR (I believe this was later PRR) which connected to the Camden & Amboy (later PRR) south of downtown Hightstown and continuing further south through Mt Holly. I have never noted any direct rail access or abandoned ROW leading over to McGuire AFB which I find odd. Perhaps all the aircraft maintenance materials as well as the airman moved through the FT. Dix Facilities and was trucked next door to the airbase? I have seen threads here that mentioned this rail line lasted into the early '70s before it was abandoned.
As far as the grade crossing over St Hwy 37, that would be the siding off of the Barnegat Branch that passed through Toms River on its way down south and connected at Lakehurst. The siding was primarily to drill the Toms River Cincinnati Chemical Corp, later bought by Ciba Geigy and then shut down in the early '90's. It too is a large Environmental Remediation site. The Barnegat branch no longer runs any further than the siding since the mid '70's (?) and later all trackage south was ripped up. The trackage is now known as the Toms River Industrial Track. Every now and then, you will see threads discussing this trackage under the Southern Secondary. I have not heard of any action down there in quite a while, 6-12 mos?. The last customer I was aware of was Suburban Propane at the Rt 37 crossing. They had closed their store but I thought they were using it as a distribution ctr.
