Claims12
A method for providing rail worker safety, comprising:
- transmitting a first request to take a section of railroad track out of service, the first request being sent from a first rail worker device to a dispatcher device;
- transmitting a second request for job site information from the dispatcher device to the first rail worker device;
- inputting job site information responsive to the second request into the first rail worker device, wherein the job site information includes an identification code, a location coordinate, and one or more scan-in confirmation signals;
- transmitting the job site information to the dispatcher device from the first rail worker device;
- and
- displaying a notification on the dispatcher device that the first request is approved.
