What is the Color Train?

The Color Train, officially known as the Busan Green Bus, is a bus rapid transit (BRT) system that was launched in 2001. It's designed to provide fast, efficient, and comfortable public transportation, connecting major attractions, universities, and residential areas across Busan. The system is color-coded, with each route identified by a specific color, making it easy for passengers to navigate and plan their journeys.
