In order to provide a comfortable riding space for passengers, the use environment was emphasized in the design of the smart electric train, CCTVs are installed inside compartments to allow the electric train driver to quickly respond to emergency situations, and a function to automatically transmit train operation and failure information wirelessly is implemented, making scientific and systematic maintenance possible.

By utilizing the integrated railway wireless communication network (LTE-R), which utilizes cutting-edge LTE technology, a smart predictive inspection system that enables real-time monitoring of the status information of major train devices, diagnosis of train conditions, and failure analysis before a failure occurs is implemented in the smart electric train.

For the new smart electric train, 1,500V direct current is used for electric supply to the electric train, the traction motor type of the electric train is a permanent magnet synchronous motor (PMSM), and the VVVF control method and IGBT power conversion element are used for the control device. By maintaining the electric brake until the electric train completely stops, wear of the brake system is delayed, reducing the generation of fine dust and increasing energy efficiency. Busan Transportation Corporation plans to introduce 272 cars by 2026.
