Of two communications systems installed in Chesapeake and Ohio's Wyoming yard, one includes 48 talk-back speakers and 21 paging speakers, and other base radio station which picks up calls made by car checkers using walkie-talkies to read numbers on cars in yard; two new interlockings at east end of yard expedite arrival and departure of trains.
