The territory in which the TieTek ties are located carries predominantly 286,000 lb. coal cars. To date, these ties have approximately 1,500 MGT (MGT=million gross tons) accumulated. The composite tie shows little if any indication of plate cutting into the tie; also there is no indication of any backing out of either the cut spike or lag screw. We continue to look to TieTek for a good quality composite tie product.
