UMTA, through Transportation Systems Center, has sponsored development of universal concrete cross ties for North American transit track. Design, preparation of preliminary specification and laboratory testing extended from 1975 through 1979. Two types, a monoblock and a two-block design, were developed which could be used with any of three fastener systems. Field testing was delayed when it was found U.S. transit track specifications would not accommodate the "standard" ties and possible alterations are being studied.
