  Extensive studies and developments have been conducted on the high strength steel (e.g. HT780). By using it, the member of bridge can be slenderized and its weight reduced. So, it has been applied to special long span bridges. There are, however, no records of usage for railway bridges because its application to railway structures is not allowed in the Design Standard for Railway Steel Structures. This paper reports the applicability of the high strength steel to railway structures, which is based on a trial design of composite girder railway bridges for 40 to 70-meter span lengths.
