Wheel Slip Testing

One of our customers, David Simpson at LTEX, took the time to demonstrate the effectiveness of our system at increasing the lifting capacity of a locomotive compared to the OEM equipment. He took two EMD GP15 locomotives, hooked each one up to 3 six-axle locomotives, turned on the air brakes on the trailing locomotives, and took the GP15s out onto a 1/8 mile test track. One of the locomotives had a TMV TECU on it and the other still had the original OEM equipment.

As a test, it was designed to demonstrate how effective the TECU is at increasing the lifting capacity of switchers and load switchers. You can see the results in this video.

GP15 locomotives were built between 1976 and 1982. They are equipped with 1500 horsepower 12 cylinder engines.

Why is this test important? In a switching yard, small locomotives are constantly moving cars around to build a longer train (consist) and they want the power to be able to lift the train and do it effectively all day and every day. If they try to lift too much, they lose momentum and stall out. This wastes time, as they have to back up and have another go, call for help from another locomotive, or even split the train in half and make the run twice. This is especially an issue in bad weather when the rails get wet or icy and there’s less friction. As this test demonstrated, the TMV TECU significantly increases the lifting ability of the GP15, and will do the same for your diesel locomotives.

Thank you, David, for taking the time to do this work! If you are interested in leasing a locomotive with a TMV TECU installed, please contact LTEX here.

TMV Control Systems Honored to be part of Cummins QSK95 Tier IV Project


TMV Control Systems was honored to be an integral part of a project to repower an SD90MAC locomotive with a Tier IV Cummins QSK95 engine.

The scope of TMV’s work included the following:

  1. Engineering and building the interface between the TMV Traction Engine Control Unit (TECU) and the Siemens traction control system
  2. Communicating with the Siemens traction control system and its inverters that drive the AC traction motors
  3. Interfacing with and controlling the QSK95 engine through the QSK95 engine control module
  4. Interfacing with the locomotive train lines to allow communication with other locomotives in the consist
  5. Exciting and controlling the main generator
  6. Controlling the 2nd small generator set to allow for engine stop/start functionality
  7. Controlling power and dynamic braking
  8. Track testing to ensure system functionality and to maximize tractive effort
  9. Remote monitoring of the locomotive through a cellular link
  10. Integrate the thermal management and emissions control to help minimize exhaust emissions

This project allowed Cummins to field test their Tier IV QSK95 engine to ensure it complete functionality as power for a high horsepower freight locomotives.  The locomotive is currently in revenue service at the Indiana Railroad.

Check out this video for more on how the Indiana Railroad is using the locomotive in revenue service.

Looking Forward To Railway Interchange!







Just a reminder that we’ll be exhibiting at the Railway Interchange in Minneapolis next week. We’ll be in booth 3522.

Railway Interchange 2015 – October 4-7, 2015


We’re excited to announce that we will be at Railway Interchange 2015 in Minneapolis, Minnesota October 4-7, 2015!

We’re interested in talking to members of mechanical teams who are short on power and interested in upgrading their older locomotives rather than purchasing new equipment. Our TECU could give you over 20% more tractive effort and adhesion, allowing you to lift significantly more with your current equipment. Our customers brag about the great work that they get from their locomotives. We’d be happy to have you join them.

More details about booth location and on site staff coming soon!

ASLRRA Connections 2015






We’re excited to let everyone know that we will be at the American Short Line and Regional Railroad Association annual convention in Orlando at the end of the month. If you’re at the show, please drop by and say hello.

We’re also interested in talking to short line owners who are tired of high maintenance bills and low performance from their equipment. Our customers brag about the great work that they get from their locomotives. We’d be happy to have you join them.

If this is something you’re interested in, drop by and see us at booth 304!

Merry Christmas and Happy New Year!


We would like to wish all our customers, suppliers, friends, and neighbours a wonderful Christmas season!

Our offices and labs will be closed between Christmas Day and New Year’s Day. We will be happy to help you again in the new year.

CP Holiday Train Arrives In Cambridge

This past week the CP Holiday Train arrived in Cambridge near our facility.​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​ CP Holiday Trains travel through dozens of communities across the continent, raising food and cash donations for food banks in local communities.









Because it was during the day, there were lots of families with young children who came out to see the train and show. It’s great to see the fascination that children of all ages have with trains.











As usual, the stage opened up and the band played a few numbers.









How does the band manage to play in sub-zero temperatures? The guitarists must get used to playing with cold fingers. The rest of the band is wearing gloves. Only in Canada!









Then the local dignitaries came out and CP Rail made a donation to a local food bank.









It’s great to see the generosity of the rail industry, particularly CP Rail, and its commitment to the local communities that are part of its network.









We wish the staff of the CP Holiday train safe travels and every success in their mission to provide healthy, nutritious food to communities across North America.

Happy Homecoming!

TMV Control Systems Inc. is pleased to announce that we’ve settled into our new home in Cambridge, ON.









Located at the junction of two Canadian Pacific subdivisions, and on a major regional road, our new location is near major highways and easily accessible.

Our rear entrance includes truck access with large roll-up doors to allow easy shipping of large, palletized material. While working on our regular production, we have also been spending time during the past year fixing up the interior and exterior to make it suitable for ongoing business.









As you can see in Google’s Street View, the facility looks significantly different than it did in 2009 when the Google car came by.

At 13,000 square feet, the facility is more than 5 times larger than our previously facility. We are now set up to deal with large orders. In addition, we now able to continue to expand our ability to assemble locomotive electrical cabinets with our locomotive control system pre-installed.

If you are ever in the area, please feel free to stop by. We would love the opportunity to show you around our facility and discuss how we can help you with your locomotive refurbishment and modernization projects. If you could, it would be helpful to email us in advance so that we are prepared for your arrival.

Happy Thanksgiving!

We are very thankful for all our customers and suppliers and the relationships we have with them.
