Since September 2011, SDD17 diesel locomotive equipped with TEC traction control and display system has repeatedly completed long-distance heavy-duty moves between Riyadh and Dammam port on many occasions. Good news from Saudi Arabia says that SDD17 diesel locomotive has run successfully and TEC products on it performed well with continued stability, which brought high praise from end customer of Saudi Arabia.

TEC micro-processor control and display system on this diesel locomotive exported to Saudi Arabia includes micro-processor controller, displaying equipment, voltage-rising filter modules etc. The locomotive often ran across deeply desert, at temperatures up to 43.3 ℃ in the afternoon. In the depths of desert, the roadbed was totally submerged in sand. Airflow produced massive sandstorms on the sides of the locomotive due to wind direction changes. All these bad working environments affected the normal operation of the products.

Finally, TEC products passed the high temperature, harsh sand environment tests successfully. TEC software technology of displaying equipment made a breakthrough innovation by overcoming the difficulty of the Arab hieroglyphs showing in highly legible way. It is the fist time that its human-machine interface adopting three language displaying, Chinese, English and Arabic and the languages can be switched freely. Such technology takes the leading position in its same industry.

 Because of elaborate design, careful commissioning on site and good performance after delivery, TEC got a high praise by CSR Qishuyan Locomotive Co.,Ltd and end user of Saudi Arabia.  The successful Saudi diesel locomotive project performance in Saudi Arabia wins good reputation for TEC and this will help TEC to develop the Middle East and other overseas markets.
