246111000 | GRADE-CROSSING TRACK PROTECTION | 9 |
20100108823 | SYSTEM, METHOD AND APPARATUS FOR RAILROAD GATE FLASHER ASSEMBLY HAVING A SEALED, RODENT-PROOF CONNECTION BETWEEN IN-PLACE FOUNDATION AND UTILITY MAST - A railroad crossing gate flasher assembly has a sealed, rodent-proof connection for electrical cables that pass from the foundation to a junction box. A clearance between the bottom of the junction box and the top of the foundation is sealed with a plate to prevent rodents from accessing the cables. The seal plate is mounted to the bolts that extend from the foundation and is leveled after it is inserted onto the bolts. The junction box is lowered onto the seal plate and attached to the same bolts so that the junction box also is level. The seal plate has an opening, coupling and conduit for protecting the cables. | 05-06-2010 |

20090194642 | GATE MONITORING SYSTEM - A monitoring system and method is provided for monitoring the lighting and the gate arm position at a railroad crossing. | 08-06-2009 |
20110155863 | METHOD AND APPARATUS FOR OPERATION OF RAILROAD PROTECTION INSTALLATION - A method and a device operate a railroad security system having trackside devices for specific functions. In order to reduce the number of cable connections, control of a first trackside device is provided by a data message generated as required by a second trackside device, in particular a signal box, the data message being transmitted wirelessly. | 06-30-2011 |
20110284698 | GATE MONITORING SYSTEM - A monitoring system and method is provided for monitoring the lighting and the gate arm position at a railroad crossing. | 11-24-2011 |
20120132758 | VITAL SOLID STATE CONTROLLER - A vital programmable logic device (VPD) is provided having at least two microprocessors. The VPD is configured to provide failsafe operation of a vital control system while operating in a closed circuit environment. In at least one embodiment of the present invention, railroad grade crossing signals are controlled by the VPD. | 05-31-2012 |
20120292457 | APPARATUS AND METHOD FOR CONTROLLING REMOTE TRAIN OPERATION - A method of verifying clearance of a rail crossing includes: (a) detecting the presence of a train near the crossing, the train being equipped with a locomotive control unit; (b) in response to detection of the train near the crossing, generating a unique code; (c) capturing an image of the crossing; (d) transmitting the unique code along with the image to a remote operator control unit; (e) using the locomotive control unit, waiting for a response from the operator control unit containing the unique code; and (f) if the response containing the unique code is received by the locomotive control unit, permitting further operation of the train and, if the unique code is not received by the locomotive control unit, carrying out an automatic response which prevents movement of the train through the crossing. | 11-22-2012 |
