Rail condition monitoring system with carriage

1. A rail condition monitoring carriage for use on a railroad track, comprising:

at least one frame movable along the railroad track;

an ultrasonic rail condition monitor disposed on said at least one frame and configured for ultrasonically monitoring condition of the railroad track and transmitting said condition data to a remote location;

said ultrasonic rail condition monitor including an ultrasonic sensing wheel constructed and arranged for rolling upon a top surface of a rail of the railroad track;

a gage measurement device disposed on said at least one frame for monitoring a gage value of the track, collecting gage data and transmitting the gage data to the remote location;

said gage measurement device including at least one horizontal actuator on said at least one frame and associated with a laterally displaceable sub-frame carrying said ultrasonic sensing wheel, said at least one horizontal actuator configured for exerting a gage out pressure on said laterally displaceable sub-frame;

and a control system connected to said rail condition monitor and said gage measurement device for receiving the collected data and evaluating same.

2. The carriage of claim 1 , further including a data evaluator component of said control system configured for receiving said rail condition data and said gage data and comparing relatively recent condition and/or gage data with previously collected and stored condition and/or gage data for detecting changes in the collected data.

3. The carriage of claim 1 wherein said control system is configured for aligning said ultrasonic rail condition monitor automatically.

4. The carriage of claim 2 wherein said data evaluator is configured for transmitting alarm signals in the event said compared data is determined to indicate that rail maintenance is needed.

5. The carriage of claim 1 including said at least one frame and said at least one laterally displaceable sub-frame being configured for movement together along the railroad track.

6. The carriage of claim 1 , being configured for being towable by a conventional hy-rail vehicle.

7. The carriage of claim 1 , having onboard power, fuel and water supplies and configured to be towed as a complete unit by a conventional hy-rail vehicle.

8. The carriage of claim 1 wherein said ultrasonic monitor is prevented from losing contact with the track section being tested by down pressure exerted on said at least one frame by a generally vertical fluid power actuated cylinder.

9. A rail condition data system, comprising:

A rail condition data system, comprising:

a unitized mounting substrate;

an ultrasonic rail condition monitor disposed on said substrate and configured for ultrasonically monitoring condition of a railroad track and transmitting said condition data to a remote location;

said ultrasonic rail condition monitor including an ultrasonic sensing wheel constructed and arranged for rolling upon a top surface of a rail of the railroad track;

a gage measurement device disposed on said at least one frame for monitoring a gage value of the track, collecting gage data and transmitting the gage data to the remote location;

said gage measurement device including at least one horizontal actuator on said mounting substrate and associated with a laterally displaceable sub-frame carrying said ultrasonic sensing wheel, said at least one horizontal actuator configured for exerting a gage out pressure on said laterally displaceable sub-frame; and

a control system connected to said rail condition monitor and said gage measurement device for receiving the collected data and evaluating same.

10. The system of claim 9 , further including:

a water tank disposed on said mounting substrate;

a water pump connected to said tank and to said mounting substrate; and

an air compressor disposed on said mounting substrate.

11. The system of claim 9 wherein said mounting substrate is a frame movable upon the railroad track and is hitch mountable.

12. The system of claim 9 wherein said control system is configured for comparing data transmitted from said monitor and said device and comparing said data with pre stored data to determine if rail maintenance is required.

13. The system of claim 9 wherein said mounting substrate is selectively connectable to a rail maintenance vehicle and independently operable relative to the rail maintenance vehicle.
