Abstract: Systems and methods are provided for a gearcase of a motor and wheel set assembly configured to enclose a gear set, including a first case element, a second case element configured to mate with the first case element to contain lubricating oil for at least the gear set and a pinion, and a rubberized seal. In one example, a system may include permanent rubberized seals sealing an opening configured to receive the pinion, an interface between the first case element and the second case element and a bearing cap.

Abstract: A method of controlling operation of a train (T) for passage of the train through a tunnel. The train has a plurality of locomotives (L1-Ln) pulling the train. The position of the lead locomotive relative to the tunnel entrance is determined, as is the amount of time before the train enters the tunnel. Each locomotive is separately configured for passage through the tunnel as a function of performance characteristics of the locomotive and the locomotive's current operating status, as the train approaches the tunnel. Once the train enters the tunnel, the performance characteristics of each locomotive are continually monitored. The performance requirements for one or more of the locomotives are then dynamically changed as a function of conditions within the tunnel and the current performance characteristics of each locomotive. This is done to maintain a sufficient combined performance capability from the locomotives to move the train through the tunnel.

Abstract: A material in the form of a sheet for enveloping a bale of agricultural material is coated with or contains a preservative in order to prevent spoilage of wrapped bales of agricultural material by aerobic organisms.
