  • Patent number: 11632522
    Abstract: The video recording system comprises a video recorder and one or more cameras which is specially designed to record video on the exterior and interior of a locomotive. The system is capable of withstanding the railroad environment, and has been designed to maximize safety and to minimize liability. The video recording system is capable of recording video on at least two drives (same video or different video on at least two drives) thereby creating redundancy in case one of the videos is unclear and/or damaged.

  • Patent number: 11162669
    Abstract: An exemplary lantern comprising a signal member which serves as a safety feature to warn workers operating in a railyard of dangerous or potentially dangerous conditions. An exemplary lantern comprising a breakaway handle mechanism that allows the handle of the lantern to break away from the body of the lantern. An exemplary lantern may comprise a ratcheting mechanism that allows the handle to rotate relative to the body of the lantern, thereby allowing the lantern to be arranged on the ground in a variety of different positions.

  • Patent number: 9970600
    Abstract: A light stick, primarily useful in the locomotive industry for signally between train personnel, includes a longitudinally extending housing which contains a first light source and a second light source. The first light source provides for general purpose illumination of the light stick. The second light source provides illumination primarily for purposes of signaling. The light stick may include a lens cap which is positioned at a forward end of the housing, and from which the illumination from the second light source may extend. Preferably, the light that is emitted from the lens cap has a blue color for purposes of railroad signaling.

  • Patent number: 9914466
    Abstract: A reverser handle comprising a key component integrally associated with a light component. In an exemplary embodiment, the light component comprises a cap which houses a light source, such as, e.g., a plurality of light emitting diodes, a light bulb, or a photoluminescent material which allows the cap to glow in the dark. The key component comprises a body having extending therefrom a flange which is configured to actuate a control stand. The light component preferably comprises a blue light emitting light source to comply with a blue flag safety procedure.

  • Patent number: 9499180
    Abstract: A locomotive headlamp comprising one or more light emitting diode (“LED”) bulbs, wherein the headlamp is ideally suited for reducing the parasitic load of the locomotive by up to about 86 percent, and which is designed and installed in a locomotive's headlight housing to cause the heat generated by the one or more LED bulbs to prevent snow and ice impaction around the locomotive headlamp, and to prevent damage to the electronics and/or circuitry used to operate the one more LED bulbs from the locomotive's power source.

The key component which comprises a body having extending therefrom a flange which is configured to actuate a control stand. In another exemplary embodiment, a reverser handle comprises a key component comprising a body having extending therefrom a flange which is configured to be received within the control stand, and which is further configured such that the key component cannot actuate the control stand. The light component preferably comprises a blue light emitting light source to comply with a blue flag safety procedure.
