The Department of Veterans Affairs also said it is aware of the situation.
A spokesperson for the National Cemetery Administration said the headstones will be recovered and that it will check to ensure that the veterans named on them have properly marked graves.
A headstone with James A. Palenik’s name was among those found at the rail yard. Online records show Palenik was 19-years-old when he was killed in action in Vietnam in 1968.
Records also show that Palenik is buried at Resurrection Catholic Cemetery in Justice.
The cemetery has not responded to NBC 5’s request for comment.
Paul Grasmehr, reference coordinator at the Pritzker Military Museum & Library, said veteran headstones can get replaced for any number of reasons, including misspellings or discovered acts of valor awards.
