The reporter learned from Tianjin Rail Transit Group that on June 25, 2024, the first electric bus of the adjustment project of Tianjin Metro Line 5 was successfully transported to the Liyuantou depot, and static and dynamic commissioning and other work will be carried out in the future.
It is understood that the adjustment project of Tianjin Metro Line 5 is an extension of the existing Metro Line 5, starting from the west side of Liqizhuang South Station of Metro Line 5 and ending at the north of Jinghua East Road on the south side of Liyuantou Depot. The subway line 5 adjustment project procurement of electric buses are B type cars, the maximum operating speed of 120 km / h, and the existing line 5 train is different, the new train for 3 EMUs, can be dynamically adjusted according to operational needs, the implementation of "3 + 3" online "dismantling, merging" (unhanging) of the driving organization, better to achieve the peak / peak period volume, efficiency and energy saving efficient matching, the technology is also the first application in the field of Tianjin rail transit.
Green subway, energy saving and emission reduction
The train purchased this time adopts the advanced energy-saving concept, optimizes the overall structure of the body, and reduces the weight of the whole vehicle by about 5%; The new train adopts a full-top lighting system with a light sensor, which can automatically adjust the brightness of the interior lighting according to changes in the external environment, with an energy-saving effect of 30%; The new train uses inverter heat pump air conditioning, which effectively adjusts the temperature and humidity in the car, purifies the air in the passenger compartment, and saves energy by 15%-35% compared with fixed-frequency air conditioning, making it more comfortable for passengers.
Intelligent management, accurate and efficient
Compared with the existing train, the new train has applied many new technologies, but also more intelligent, the train has the function of real-time monitoring and remote reminder of the comprehensive status of the vehicle, and at the same time adds a variety of detection systems such as anti-fatigue driving and online detection, which effectively improves the safety of the train.
