A ride-through control system for operating locomotives in a train includes a geographic position sensor configured to generate a signal indicative of a geographic position of a locomotive of a train, and a controller configured to receive the signal indicative of the geographic position of a locomotive and compare the geographic position of the locomotive with one or more pre-determined geographical locations or regions previously identified as geo-fences. The controller may also be configured to receive one or more locomotive operational signals indicative of at least one of an operational parameter, a fault, and a maintenance request associated with the locomotive, determine whether the geographic position of the locomotive coincides with a geo-fence characterized by conditions that may affect the ability of the locomotive to meet a trip objective if the locomotive were to slow below a threshold speed within the geo-fence, and generate a ride-through control command signal to prevent the locomotive from slowing below the threshold speed within the geo-fence based on at least one of the one or more locomotive operational signals and a user permission level.

Train asset availability and reliability management system
A method for managing train assets increases the time between required maintenance of the train assets, improves the future availability of the train assets, or increases the likelihood that the train assets will successfully complete future missions. A controller may receive from a sensor on a train asset a real-time signal indicative of at least one of a measured operational characteristic or a maintenance activity associated with the train asset, receive from a memory prognostic data providing information on a likelihood the train asset will complete a mission, and simulate a hypothetical operational scenario (HOS) based at least in part on the prognostic data and involving one or more train assets. Predictive data associated with the HOS may provide information on a likely benefit to a train asset from a change in at least one of an operational parameter, designated operational configuration for the train assets, or maintenance-related activity.

An aftertreatment system for an engine is provided. The aftertreatment system includes a housing member having a bottom end and a top end. The housing member includes an inlet chamber and an outlet chamber defined adjacent to the bottom end and the top end, respectively. The inlet chamber is configured to receive exhaust gas via an inlet port which is coupled to an exhaust conduit of the engine to receive exhaust gas. The outlet chamber is configured to discharge the exhaust gas via an outlet port which is coupled to an exhaust pipe to discharge exhaust gas. The housing member also includes a catalytic chamber disposed between the inlet chamber and the outlet chamber. The aftertreatment system includes one or more catalyst carrying members disposed within the catalytic chamber. The one or more catalyst carrying members are configured to communicate with the inlet chamber to receive exhaust gas therethrough.
