Abstract: According to some embodiments, a tank car comprises a tank; a top platform coupled to a top of the tank comprising a walking surface; a walkway platform extending longitudinally between an end of the tank and the top platform comprising a walking surface disposed above a line tangent to the top of the tank; and a closure plate coupled to an end of the walkway platform proximate to the top platform. The closure plate extends below the walkway platform to cover access to a space between the walking surface of the walkway platform and the top of the tank. In particular embodiments, the top platform comprises a first and second handrail assembly and a space between the handrail assemblies for accessing the walkway platform. The closure plate covers access to the space between the handrail assemblies and below the walkway platform.

Abstract: According to some embodiments, a tank car comprises a tank shell with reinforcing bars extending longitudinally along a bottom of the tank shell. The tank car also comprises clips coupled to the reinforcing bars. A jacket standoff wraps around at least part of a lateral circumference of the tank shell. Each end of the jacket standoff is coupled to one of the clips. According to some embodiments, a clip for attaching a jacket standoff to a tank car comprises a first portion for coupling to a mounting surface of a tank shell; a middle portion shaped to generally conform to a contour of a side of the mounting surface; and a second portion, opposite the first portion, comprising a recessed portion to accept an end of the jacket standoff and positioned such that the second portion is located proximate to the tank shell but not attached to the tank shell.
