A transport vehicle for traveling in a low-pressure environment structure is provided. The transport vehicle may include a deployable decelerator configured to deploy from the transport vehicle to decrease a distance between the transport vehicle and the low-pressure environment structure and a communication network that monitors and collects a plurality of operation parameters from the transport vehicle and the low-pressure environment structure to control deployment of the deployable decelerator based on a plurality of predetermined triggering events.

A system and a control system for selectively preventing movement of a locomotive is disclosed. The control system may comprise a plurality of access control devices for the locomotive, with each access control device including a status indicator, and being configured to activate or deactivate the status indicator based on user input received by any of the plurality of access control devices. Each access control device may also be configured to transmit status data indicative of a status of the locomotive to a locomotive controller, with the status either being a blue flag status or a ready status, wherein at least one of the access control devices is a mobile device not mounted to the locomotive.

A vehicle system comprises an interface assembly and a controller both on board a first rail vehicle. The interface assembly comprises one or more mechanical couplers, fuel couplers, fluid couplers, and electrical connectors, to detachably couple the first rail vehicle to a separate, adjacent fuel tender vehicle, for the transfer of one or more of fuel (e.g., compressed natural gas) from the fuel tender vehicle to the first rail vehicle, heated fluid from the first rail vehicle to the fuel tender vehicle (e.g., for regasification of liquid natural gas stored in the fuel tender vehicle to the compressed natural gas), or electrical power and/or control signals between the first rail vehicle and the fuel tender vehicle. The controller is configured to at least partially control operations of the first rail vehicle in relation to interfacing with the fuel tender vehicle for fuel transfer, heated fluid transfer, etc.

A transport vehicle for traveling in a low-pressure environment structure is provided. The transport vehicle may include a deployable decelerator provided on the transport vehicle and configured to deploy from the transport vehicle to decrease a distance between the transport vehicle and the low-pressure environment structure. When the decelerator is deployed the decelerator is configured to increase drag forces opposing a direction of motion of the transport vehicle and decelerate the transport vehicle.

The present invention discloses an overhead rail and trolley apparatus and method. The apparatus provides an overhead rail having one or more tracks. A wheeled trolley having a wheel or wheels travels upon the tracks. A stop unit on the rail is positioned to selectively halt the trolley. There is a cutout section on the rail and an insert that is attached to the rail at the cutout. The trolley wheels engage the upper surface of the insert when the trolley is halted by the stop unit. A plating on the insert increases the hardness of the insert upper surface. The insert helps prevent and/or at least lessens wear of apparatus when the trolley is halted by the stop unit.
