A nice experience I had is a train trip in Chile, the train on that occasion was new, and it was very punctual, I went with 4 other people, a visit and tourism trip; The train had air conditioning, restored, and like most trains, huge windows to appreciate the landscapes of this beautiful country.
The seats were very spacious and comfortable, and had built-in cell phone charging ports, and something that fascinated me, the hallways are very spacious, I spent the entire train walking to go to the cafeteria and the bathroom without much difficulty.
Regarding the prices, they are very similar to the buses and one thing I didn't like was that they charge you additional for the size of the luggage, I had to pay 5 dollars more for my luggage.
But in general, the train and the trip were spectacular.
