| 20120000987 | SHALLOW FLANGEWAY RAIL SEAL - A rail seal for sealing the gap between a rail and a concrete panel in a railroad crossing so as to provide a generally even or level surface for vehicular or pedestrian traffic while still providing an appropriate rail structure for receiving and guiding the train wheels along the tracks is provided. More particularly, the upper surface of the rail seal is formed with a recessed portion or flangeway for receiving the flanged-end of a train. The flangeway or recessed portion, however, is formed so that the surface of the flangeway lies in a plane above the bottom of the rail head but below the upper surface of the rail head, thereby providing a “shallow” flangeway. The provision of a “shallow” flangeway helps to reduce the risks associated with vehicular and/or other pedestrian traffic that must access or cross the railroad tracks. Specifically, the shallow flangeway helps to prevent the heels of pedestrian shoes or the smaller width bicycle, stroller or wheelchair wheels from becoming trapped in the gaps typically associated with railroad crossing structures. | 01-05-2012 |

| 20120000988 | Removable Rail Seal - A rail seal for sealing the gap between a rail and the surrounding surface material in a rail crossing or track construction, wherein the rail seal is removable from the gap and can be re-installed in the gap without damaging the surrounding surface material. More particularly, the rail seal is formed with an integral hinge element that has a closed position and an open position wherein an upper portion of the rail seal is released from and extends upwardly away from a lower portion of the seal body thereby imparting additional flexibility to the seal body. To remove the rail seal from the gap adjacent the rail, the rail seal can be manipulated so as to be pulled free from the gap. In order to re-install the rail seal, the additional flexibility provided by the hinge element allows the rail seal to be manipulated and deformed as required so as to be re-installed within the open gap. The rail seal may also be formed with anchor recesses at opposed ends of the rail seal body for receiving anchoring keys which help to secure the rail seal within the gap so as to prevent longitudinal movement and shifting of the rail seal over time. | 01-05-2012 |
