The TECU system provides a way to upgrade older locomotives or equip new locomotives with an up-to-date microprocessor-based control system. It features improved wheel slip control and typically can increase adhesion by 20-30 percent, the company says. The TECU comes in two models — a TECU-Lite (2 Module) and TECU (5 Module). The TECU-Lite system is small and easy to install in older switcher locomotives, the company says, adding that the larger TECU system can control the latest high-horsepower or multi-engine locomotives. All TECU systems can be equipped with Auto Engine Stop/Start (AESS) as an option.
