Kevin writes … Thank you for posting the info and photos of the 723rd Railway Operating Battalion on the blog.  I stumbled onto it, and was interested---

In the HQ photo the Lt. McClooney seated in the front row center—he was my uncle.  James E. McClooney.  He now rests at Arlington National Cemetery here in Washington DC.

I heard many stories during visits to my uncle, while growing up as a child in the 1960s about the 723rd and his work in the Railway Operating Battalion.  At that time he was a civilian instructor at the Army Transportation School at Ft. Eustis
