I enjoy to travell on an overnight train in China Overnight train travel usually lasts 10 -12 hours or more and are classes as K, T or Z trains:K trains have a top speed of 120 km/h and are the slowest overnight trains as they make a lot of stops en-route.T trains are faster than K trains with a top speed of 140 km/h and stop less often, in major cities only.Z trains are a direct express train with top speeds of 160 km/h and have the fewest stops en-route to the destination.The longest train routes can last up to 2 days.
