    • A composite roof having a core encapsulated in multiple layers of fiber reinforced plastic is provided. The composite roof may be mounted on a conventional railway car during initial manufacture or used to replace a damaged steel roof on a conventional railway car. The layers of fiber reinforced plastic provide non-corrosive and non-leaking exterior and interior surfaces for the composite roof. The core may be formed from various materials which provide improved resistance to heat transfer between the interior and the exterior of an associated railway car. The composite roof may be mounted on an enclosed structure having a pair of end walls, a pair of side walls and a floor. An opening may be formed in each side wall to allow access to the interior of the railway car. A top retainer and guide rail assembly will typically be mounted above each opening to allow installing a door to control access through the respective opening. A strip of fiber reinforced plastic is preferably attached to the top retainer and guide rail assembly to form a composite rain gutter over each opening.
    • 提供了一种具有包封在多层纤维增强塑料中的芯的复合屋顶。 复合屋顶可以在初始制造期间安装在传统的铁路车辆上,或者用于替代传统铁路车辆上损坏的钢屋顶。 纤维增强塑料层为复合屋顶提供非腐蚀性和非泄漏的外表面和内表面。 芯可以由各种材料形成,这些材料提供对相关联的铁路车辆的内部和外部之间的热传递的改进的抵抗力。 复合屋顶可以安装在具有一对端壁,一对侧壁和底板的封闭结构上。 可以在每个侧壁中形成开口以允许进入铁路车辆的内部。 顶部保持器和导轨组件通常安装在每个开口上方,以允许安装门以控制通过相应开口的通路。 纤维增强塑料条优选地附接到顶部保持器和导轨组件,以在每个开口上形成复合雨沟。
