Abstract: According to some embodiments, a railcar monitoring system for monitoring one or more conditions associated with a railcar comprises a railcar controller and one or more sensors disposed throughout the railcar and communicably coupled to the railcar controller. The railcar controller is configured to exchange data with the one or more sensors and transmit data from the one or more sensors to a remote location. An amount of data exchanged between the railcar controller and the one or more sensors is controlled based on a railcar context. The railcar context is based on a location and/or activity associated with the railcar.

Abstract: In various embodiments, cylinder assemblies are coupled in series pneumatically, thereby reducing a range of force produced by or acting on the cylinder assemblies during expansion or compression of a gas.
