     침목이 평판형의 상부 플렌지(5)와 평판형의 하부 플렌지(6)를 가지고, 상부 플렌지 및 하부 플렌지의 폭 방향으로 양 플렌지의 중앙부를 접속하도록 수직 웨브(7)가 침목 길이 방향으로 연속하여 형성되어 있다.  철 침목이 폭 방향으로 대략 I자형 단면을 가지고, 침목 길이 방향의 양 단부면이 돌출 방지판(8)으로 봉쇄되고, 상부 플렌지(5), 하부 플렌지(6), 수직 웨브(7)와 돌출 방지판(8)으로 둘러싸인 공간이 침목의 측면에서 외부로 개방되어 있다.  레일로부터 전달되는 하중이 상부 플렌지 및 하부 플렌지 양자를 통해 밸러스트에 전달된다.

Abstract: 본 명세서에는, 80중량% 이상이 열가소성 폴리에스테르로 구성되어 있는 기저 층과 하나 이상의 외부 층을 갖는, 투명하며 2축 배향된 폴리에스테르 필름으로서, 외부 층이 에틸렌 2,6-나프탈레이트 단위 40중량% 이상과 에틸렌 테레프탈레이트 단위 40중량% 이하 및/또는 지환족 또는 방향족 디올 및/또는 디카복실산으로부터의 단위를 포함하는 중합체 또는 중합체 혼합물로 구성되어 있으며, 단 T g 2 값이 기저 층의 T g 2 값 이상 외부 층의 T g 2 값 이하이며, 한 면 이상의 표면장력이 35 내지 65mN/m이고/이거나 두께가 5 내지 100nm인 작용성 피복물이 제공되어 있는, 투명하며 2축 배향된 폴리에스테르 필름이 기재되어 있다. 
     당해 필름은 대기 산소에 대한 투과성이 낮다.  이는 특히 포장용으로 적합하고, 특별하게는 식품과 기타 소모품 포장용으로 적합하며, 적층, 금속화 및 인쇄용으로 적합하다.
