December, 2015: TMV was chosen as sub-contractor for NCDOT’s modernization program. Two former GO transit F59PH locomotives, like the one pictured here, were fitted with new control systems for use in the North Carolina Piedmont passenger rail service. For photos and stories of units #1871 and #1984, which were fitted with TMV systems, please see www.businesstodaync.com, www.ncdot.gov, and www.independenttribune.com.

TMV has done three GP15’s, like the ones pictured here, for LTEX in Warren, Ohio, from October 2011-July 2012. These 74V locomotives required small, two-module TECUs called “TECU-lites”.

Camino Real Regional Mobility Authority in El Paso, Texas, set out to refurbish their historical streetcars in 2015. Determined to restore the cars to a working order that will extend into the next generation, TMV Control Systems was chosen based on previous experience on New Orleans Streetcars. Keep an eye out for TECU-powered El Paso streetcars.

Metrolinx and Nippon-Sharyu hired TMV to equip the Union-Pearson (UP) Diesel Multiple Unit (DMU) train with a competent control system. Operating between Union station and Pearson Airport in Toronto, Ontario, this efficient form of public transit gets travellers from the airport to downtown in under a half hour. A total of 18 passenger units were equipped with their own TECU.

The Florida Central Railroad (one of several short line railroads run by the Pinsly Railroad Company), installed a TECU-lite on a GP11 locomotive they updated in 2017.

Knoxville Locomotive Works rebuilt and tested a locomotive with one of TMV’s Traction Engine Control Units (TECU). Formerly a GP-38, the #2250 was repowered and now contains an EPA Tier 2- compliant diesel engine. Please see the Case Study here.

Norfolk Southern set aside two GE Dash9 engines for the DC2AC project, for TMV and CAF to convert from DC traction to AC traction. TMV is working with CAF to create a turnkey traction system upgrade which can be quickly and easily installed. Testing of the first one in Olean New York. November, 2018.

TMV has done a number of MP15s, like the ones pictured here, both for Norfolk Southern and LTEX. Special applications include MP15AC, MP15AC with split cooling, and mother-slug arrangements. Since 2010, TMV systems have integrated attentively into the EMD set-up.

TECU ensures a good balance of power and versatility in the compact SW1200s, like the ones pictured here. Rain or shine, the AESS feature watches over these industrious engines. August 2010 destination: Texas. June 2011 destination: Georgia.

December 2011, LTEX asked TMV to fit an SW1500 with a TECU. Noting the similarities between the SW1500 and previously fitted MP15ACs, the modifications were easily applied. A 3-module TECU was installed with custom wiring harnesses, into a locomotive like the one pictured here.

From August 2012 until now, TMV has been fitting the TECU system to LTEX GP39s, like the ones pictured here. Various requirements have been met by adjusting the number of modules on the TECU. To facilitate input/output numbers, two-module, three-module and five-module TECUs have all been individually GP39-appropriate.

GP38s, like the ones pictured here, have been a mainstay in TMV project history. For G&W, LTEX and others, the TECU has steadily devoted itself to better power management and tractive effort. The GP38 has become a familiar platform to TMV engineers.

In 2010, the Indonesia Railway Industry (INKA) in Madiun, East Java, Indonesia, used TMV’s TECU system for the Railbus Wonogiri Project. Two engines run each Railbus as a push-pull system, and a pair of TECUs run the engines. Operators can see all the bus’s statistics on TMV’s interactive display screens. Photos by Maulana.

Two short lines from G&W, The Buffalo & Pittsburg and the Quebec-Gatineau Railway, are suited with TMV components, including control systems. High-voltage electrical cabinets were made for B&P GP40 Mother-Slugs in 2015.
