The Mugunghwa and KTX trains serve the Hwanggan to Sindong route. The KTX, South Korea's high-speed train, can travel up to 300 km/h, making the journey in about 1 hour and 15 minutes. The Mugunghwa, a slower option, takes approximately 2 hours and 30 minutes, operating at speeds around 100 km/h. Both trains offer comfortable seating, but only the KTX provides amenities such as power outlets and free Wi-Fi.
