Abrégé

Embodiments herein disclose an electric railroad retarder having a plurality of retarder modules. A retarder module comprises a gear cam assembly disposed between a first brake unit and a second brake unit. The gear cam assembly comprises a first position arm plate and a second position arm plate that are connected to a cam using a first positioning arm and a second positioning arm. The cam rotates to perform one of: compress a first brake spring, a second brake spring, a third brake spring and a fourth brake spring to hold wheels of a railcar; decompress the first brake spring, the second brake spring, the third brake spring and the fourth brake spring to release the wheels of the railcar; and separate the first position arm plate from a first spring base plate, and the second position arm plate from a second spring base plate to allow insertion of a shim.

Abrégé

The invention provides computing devices and systems for railroad control and automation in railyards and on rail lines. A computing device has a housing having a front, a back, a top, a bottom, an exposed side, and an unexposed side, as well as an interior. The interior of the housing is adapted to support a communications bus, a processor board with a digital signal processor having memory thereon coupled to the communications bus. The memory stores a unique device identification. Additionally in the interior is an input/output board coupled to the communications bus, and a user-interface board coupled to the communications bus. The front has a user-viewable screen adapted to display a plurality of alphanumeric characters, and a user-interactive input device adapted to allow a user to scroll through alphanumeric data displayed on the screen. The top has a bank of output connectors comprising a first output connector adapted to send a control signal to a first railroad device, a first microphone, and a bank of power input connectors. The bottom has a bank of input connectors comprising a first input connector adapted to accept a signal from the first railroad device, and a wire-line data communications receptacle, while the back is adapted to couple to a DIN-Rail.

The invention provides railroad path optimization method. The method determines whether at least one switch machine from a plurality of switch machines is occupied in the at least one route and detects at least one unavailable route if the at least one switch machine is occupied. Further, the method identifies at least one desired route and at least one available route associated with an origin point and at least one desired route and at least one available route associated with a destination point to identify at least one available route for the destination point. Based on the identified available route, the method predicts the at least one optimal route and ranks the at least one predicted optimal route to enable selection of a final optimal route for travel.
