Abstract

The present invention provides a locomotive security system and method, which applies a penalty brake to prevent unauthorized operation of a locomotive. The security system includes a security computer interfacing with an input device, a verification device and a locomotive penalty brake. Upon receiving appropriate identification information, from the input device, and a corresponding verification code, from the verification device, the security system allows an operator to operate the locomotive. The security system may also require reentry of the verification code periodically during locomotive operation to prevent application of the penalty brake. The system may be further used to transmit a distress signal, to signal authorities, when an unauthorized operator attempts to operate or continue to operate the locomotive.

Claims

1. A security system for use in preventing unauthorized operation of a locomotive, the system comprising:

a security computer interfacing with an input device, a verification device and a locomotive penalty brake;

the security computer operable to apply the penalty brake to prevent unauthorized use of the locomotive;

the input device operable to receive operator identity information and transmit the identity information to the security computer;

the verification device operable to receive a verification code and transmit the verification code to the security computer;

the security computer operative to compare the identity information and the verification code to determine if use of the locomotive is authorized; and

the security computer operative to apply the penalty brake when use of the locomotive is determined to be unauthorized.

2. A system as in claim 1 wherein the identity information is stored on an ID card readable by the input device.

3. A system as in claim 2 wherein the ID card also contains an encrypted verification code corresponding with the identity information.

4. A system as in claim 3 wherein the verification device is a keypad.

5. A system as in claim 3 wherein the verification code is biometric information.

6. A system as in claim 5 wherein the verification device is a biometric reader.

7. A system as in claim 1 wherein application of the penalty brake removes traction power to the traction motors of the locomotive and applies adequate braking force to prevent movement of the locomotive.

8. A system as in claim 1 including a transmitter interfacing with the security computer and operable to transmit a distress signal when the identity information and the verification code do not correspond.

9. A method of preventing unauthorized use of a locomotive including the steps of:

providing a security computer interfacing with an input device, a verification device and a locomotive penalty brake;

inputting operator identity information into the input device and transmitting the identity information to the security computer;

inputting a verification code into the verification device and transmitting the verification code to the security computer; and

comparing the identity information and the verification code and applying the penalty brake if the identity information and the verification information indicate an unauthorized operator.

10. A method as in claim 9 including initiating a reverification process signaling the operator of the locomotive after a period of time to reenter the verification code into the verification device and the security computer applying the penalty brake if the verification code is not entered.

11. A method as in claim 9 including transmitting a distress signal from a transmitter when unauthorized identity information or verification codes are inputted into the security computer.

12. A method as in claim 9 including inputting an encrypted verification code into the input device and transmitting the encrypted verification code to the security computer.

13. A method as in claim 12 including decrypting the encrypted verification code and storing the decrypted verification code within the security computer to generate a required verification code stored within the security computer.

14. A method as in claim 9 including generating a required verification code within the security computer based on operator identity information.
