Publication number: 20190248389Abstract: A method and mechanism for initiating an emergency stop for an unattended railcar is disclosed. The method may include using a trip arm placed alongside the railway tracks at a designated stop point that may contact a portable trip-cock lever arm that extends out beyond the perimeter of the railcar if the railcar reaches the stop point as it moves along the track. The trip-cock lever arm may be attached to a valve that is connected to the pneumatic brake system of the unattended railcar. As the trip-cock lever arm rotates, the valve may open to release the air pressure in the pneumatic brake system causing the brakes to engage the wheels causing the railcar to stop.Type: ApplicationFiled: February 12, 2019Publication date: August 15, 2019Inventors: Mark Charles Engelland, Trevor Michael Greer, David Alexander Shaw

Publication number: 20190248393Abstract: In an example, the autonomous vehicle (“AV”) can be configured among the other vehicles and railway to communicate with a rider on a peer to peer basis to pick up the rider on demand from a location on a railway track, rather than the rider being held hostage to a fixed railway schedule. The rider can have an application on his/her cell phone, which tracks each of the AVs, and contact them using the application on the cell phone. In an example, the AV is configured for both on-track and off track operation with different operating parameters for on-track and off track.Type: ApplicationFiled: April 20, 2018Publication date: August 15, 2019Inventor: Vinod Khosla

Publication number: 20190248395Abstract: A method secures a railroad crossing which allows a timely securing of the railroad crossing, and is particularly efficient and reliable. The method proceeds in such a way that sensor data relating to a rail-borne vehicle approaching the railroad crossing are detected by a track-side sensor device. The sensor data contains at least the current speed of the rail-borne vehicle. The detected sensor data are transmitted by the track-side sensor device to a stationary control device. A switch-on time is determined by the stationary control device taking into account the transmitted sensor data and route data. Upon reaching the switch-on time, the securing of the railroad crossing is initiated by the stationary control device. After the railroad crossing has been successfully secured, a travel permission that extends beyond the railroad crossing is determined by a control device of a train control system, and is transmitted to the rail-borne vehicle.Type: ApplicationFiled: June 1, 2017Publication date: August 15, 2019Inventors: Christoph KUTSCHERA, Jens-Harro OECHSNER, Thomas SCHMIDT
