Reducing Downtime in Railroad Maintenance

In Railroad maintenance the products and processes that have a proven track record for effectively reducing downtime rise to the top, while the ones that don’t are filtered out.  Below are a few areas where the Bartol Mag-Probe is being used in Railroad Maintenance to Reduce Downtime.

Hello Bob,

I received the probes and can’t thank you enough. As stated in the other email I’ve been using the Mag-Probes for 10 years as a locomotive electrician and it is one of the tools I use on a daily basis. With electronic fuel injection it is easier than a meter to see if voltage is present at the injector. These are some of the best probes I’ve ever used, thanks so much again for your help.



We are very grateful to all the hard working technicians in railroad maintenance that have given us all this great feed back.  If there is anything else you are doing that is creative and innovative please contact me personally at 208-321-7566. Bob Bartol

 (Special Note) The Mag-Probe Can Not be Used to Test High Current Output Relays (17-21).  In the Locomotive Interface Unit Due to one set of the Two Exposed Contacts ALWAYS being Energized and the Relay ALWAYS indicated on.

About the Author
Bob Bartol has spent his whole life working with electronics in almost every capacity and spent many hours in Physics classes. He currently holds 4 U.S. patents and has been making a living off one of the patents "The Bartol Mag-Probe" for over twenty years. Bartol Research's Mag-Probe now has a global reach and is dramatically reducing trouble shooting downtime anywhere a solenoid valve. relay, or contactor is used. F111 Air Force Projects - European Flight Competition January 1968 Bob attended electronics school in the Air Force. Upon graduation he was assigned to a fighter wing in Germany. During his assignment he prepared seven aircraft for European competition. The fighter wings aircraft won the competition. Bob then returned to the United States and taught advanced radar for two years. Two years later, he returned to Europe. During this assignment, Air Force headquarters Europe selected Bob to open a Precision Measuring Equipment Laboratory (P.M.E.L) in England. It was the first of its kind in the Air Force. Upon his return to the United States, Air Force headquarters assigned Bob to Air Force research command in Florida. This was strictly a scientific assignment for research and development. After three years he moved from Eglin AFB in Florida to Edwards Air Force Base in California where he had direct contact with the National Bureau of Standards and supported research and development aircraft. During this assignment, he designed a modification for the TF X fighter (F-111). This modification made possible an additional 9800 flying hours per year. The F111 was the first swing wing aircraft in history. General Dynamics completed the modification prior to acceptance by the U.S. Air Force. Modification of F111 Aircraft General Dynamics March 1968 As a result of increasing this flying time Bob Received an award from Edwards Air Force Base for Increasing flying time of the F111 by 9,800 hours per year. The Award was Presented by Colonel Grumbles to TSGT Bob Bartol on June 17, 1968
