A wall structure for forming a wall of a rail vehicle car body, the wall structure comprising a metal panel having an aperture formed therein; and a fibre-reinforced-plastic (FRP) strengthening system attached to the metal panel at a corner of the aperture. The FRP strengthening system comprises a stack of FRP laminae arranged such that, progressing through the stack starting from a base lamina, the area of each lamina in the stack is less than that of the previous lamina.

According to some embodiments, a system may include an additive manufacturing platform that provides additive manufacturing capability data. A customer platform, associated with a customer, may transmit an industrial asset item request for an industrial asset item. A digital transaction engine may receive the additive manufacturing capability data and the industrial asset item request. The digital transaction engine may then associate the industrial asset item request with an industrial asset definition file, and, based on the additive manufacturing capability data and the industrial asset definition file, assign the industrial asset item request to the additive manufacturing platform. The assignment of the industrial asset item request may be recorded via a secure, distributed transaction ledger. Responsive to the assignment, the additive manufacturing platform may create the industrial asset item (e.g., via an additive manufacturing printer) and provide the item to the customer.

Light-weight beam assembly and truck trailer using the same are disclosed herein. The light-weight beam assembly is a beam being a single unitary continuous piece comprising at least two cutouts cut through, at least one vertically extending supporting member and a plurality of reinforcement members. Two beams may be connected by a plurality of transversal members for use in a truck trailer.

A rail vehicle car includes at least one tank for storing gaseous fuels. The at least one tank is integrated into a car body shell of the rail vehicle, and the walls of the tank are constructed in such a way that they assume a load-bearing function within the car body shell.

A railcar head structure includes: a roof bodyshell positioned above a driver's cab window; and an underframe. The underframe includes: a pair of side sills; and a center sill located between the side sills and extending in a car longitudinal direction. A collision post is erected on a tip end of the center sill. A pillar is provided at the driver's cab window and extends so as to divide the driver's cab window. The pillar includes one end joined to the collision post and the other end joined to the roof bodyshell and couples the roof bodyshell and the collision post to each other.

The invention relates to a method for connecting a connection piece to a U-shaped ring anchor for a head module for rail vehicles, the head module consisting predominantly of fiber-reinforced plastic material and having an outer shell and the ring anchor consisting of fiber-reinforced plastic material and being arranged in the roof region of the outer shell as a stiffening means. According to the method, connecting elements are fed through the dry or matrix-material-impregnated, unconsolidated fiber reinforcement structure of the ring anchor.

A railroad train marshaling system or method includes a railroad train with cars within a platform area. Door-free cars are connected with the cars within platform area at both ends or one end and made up of at least one car with no side door for passengers to get on and off the train. When the railroad train stops at the platform, the cars within the platform area are arranged to stop within the area of the platform or corresponding to the platform. The door-free car is arranged to stop beyond platform area and passengers in the door-free car will get to the platform directly from the car within platform area. The sum of length of door-free car and cars within platform area is more than a length of the platform.

A railroad train marshaling system or marshaling method is disclosed. The railroad train includes cars within platform area which are made up of several cars; door-free cars which are connected with the cars within platform area at both ends or one end and made up of at least one car with no side door for passengers to get on and off the train. When the railroad train stops at the platform, the cars within platform area are arranged to stop within the area of platform or corresponding to the platform, the door-free car is arranged to stop beyond platform area and passengers in the door-free car will get to the platform directly from the car within platform area. The sum of length of door-free car and cars within platform area is more than that of the platform.
