The Z-class Non-Stop Express is China’s direct overnight train type, running between major cities with very few or no stops and operating on conventional tracks rather than the bullet train network, with speeds up to 160 km/h. Passengers can choose soft sleeper or hard sleeper berths, or soft seats and hard seats for their trip, and Rail Monsters offers Z-class tickets online where you can compare prices, check routes, and book your travel with simple booking steps.
