The N5 Pennsylvania Caboose No. 2457 was issued in O gauge sets from 1945 until 1947 and it was a deluxe version of the No. 2472 that was issued with Lionel’s O27 sets.
This caboose was of all sheet-metel construction that is mounted on a BLACK chassis that has steps. This caboose came with a smokestack, end hand rails, brake stands, ladders, tool box and a plastic air pump on the underside of the chassis. All versions had staple-end trucks with one or two electronic coil couplers, and interior illumination. Most of the variations have forward and backward cupola windows and "EASTERN DIV" below the number "477618" on the sides.
