Systems and methods are provided herein for modifying a railcar to transport containerized proppant. Various examples are provided, including: stripping a rotary gondola railcar, stripping a gondola hopper railcar, installing or modifying a floor on a stripped railcar, installing container braces on a floor of a railcar, installing braces between the side walls of the railcar, installing struts between the side walls of the railcar using the beam of the container as a strut, creating a mold for foam reinforcement of a railcar, installing foam reinforcement in a railcar, and transporting a container of proppant using a modified railcar. Although these examples are described in relation to a coal railcar, they can be modified to use other types of railcars as well. These examples can also be combined together to form a method for modifying a railcar.

The present disclosure relates to an autonomous rail transport system with the aid of a rail network. The rail transport system according to the disclosure comprises at least one autonomous goods-carrying rail vehicle and at least two autonomous goods terminals. The goods-carrying rail vehicle is designed to transport at least one item of goods while the goods terminals are each designed to receive and/or release at least one item of goods. The item of goods is transported autonomously from a first goods terminal to a second goods terminal with the aid of the goods-carrying rail vehicle on the rail network. The rail network of the rail transport system according to the disclosure is a streetcar-line network.

A securing assembly is adapted to secure objects to a structure. The assembly includes an attachment mechanism adapted to attach the assembly to an object in use. An elongate rod has a first end and a second end, wherein the first end is connectable to the attachment mechanism and the second end is connectable to an adjustment device. A base is adapted to connect the adjustment device to the structure in use. The adjustment device is operable to adjust a tension between the object and the structure by way of the assembly to secure the object to the structure in use.

A railroad freight car may have external fittings, such as trackside-accessible ladder fittings that permit personnel to climb onto the decks and walkways of the car. Several embodiments of movable ladder assemblies are described that provide an extended or deployed or raised position of a handhold, and a retracted or lowered, or stored position. In other embodiments, the assembly is provided with a compliant member that allows the handhold resiliently to flex when encountered by solid objects such as shipping containers.

A container to be used with trucks, semitrailers, railway wagons and ships, so as to carry out a multimodal transport where the transport by land, railway and fluvial routes is combined as needed. The container has a metal parallelepiped structure which contains a truck bed receiving the material, and one end it is mounted over a hinging resource that allows its turn regarding a lower cross axis; and at another end it is connected with a hydraulic cylinder that is fixed over the basis of the mentioned metallic structure and has its end free of its piston linked to the upper and rear cross edge of the truck bed.

An Urban Intermodal Freight System is capable of transporting large volumes and tonnage of freight by containerized or other means on a mass transit rail system. It captures excess capacity in the existing mass transit rail infrastructure to move packages, parcels, and freight by using miniaturized intermodal cargo containers that are designed to integrate seamlessly with the existing transit infrastructure, while displacing delivery trucks from increasingly crowded city streets. By enabling inbound trucks to transfer their cargo to the Urban Intermodal Freight System at a city's outskirts, freight is delivered without trucks entering congested downtown areas, greatly alleviating traffic congestion, delays, greenhouse gas emissions and other negative environmental impacts. The Linear Loading Dock and Conveyor System may have other useful applications, for example to access a facility, building or vehicle, or in other circumstances where off street truck parking or loading docks are not available.
