MRT lines, or Mass Rapid Transit lines, are urban rail systems designed to provide efficient public transportation in cities. They consist of multiple routes that connect various neighborhoods, commercial areas, and key landmarks, making it easier for residents and visitors to travel. MRT systems are typically characterized by their high frequency, speed, and reliability. These lines often feature modern trains and stations, with amenities such as ticketing machines and real-time arrival information. Many cities around the world, including Singapore, Taipei, and Tokyo, have developed extensive MRT networks to reduce traffic congestion and promote sustainable urban mobility.
