The trains are amazing

The trains are so very quiet and stable. Even the KTX which goes up to 300km/h doesn't really even feel like it's moving until you look outside at the scenery going by. These train systems are built extremely well.

I might be biased here because I just came from Thailand, where riding the train felt like trying to escape from an 18 wheeler filled with gorillas. I've got a funny video of myself trying to eat soup in the Thai railcar which I'll put up on here as soon as I get it uploaded.

The seats are comfortable, the cars are clean, and all that for $2.50 to the next city which is 50km away. This is cheaper than the bus, which is $4.
