The Elevated Trestle Set No. 111 was introduced one year after the Graduated Trestle Set No. 110 in 1956, and would continue to be in production until the end of the post-war period in 1969. It comprised 10 large piers molded in GRAY plastic, along with the hardware for mounting O, O27, and later Super O track to the piers. There are no variations, but this accessory was issued in two different boxes that we’ve shown above and to the right.
