Public transport in the US

The trains exist, usually one a day. On the South only 3 per week, on the East between Boston and Washington one per hour. The first class is a 2-seats couchette you can transform into 2 beds and with all the meals included. Second class are reclinable seats with leg rest. For the night they provide a pillow. There are one and two floor trains, being the biggest difference only more toilets in the two-floors type. There is a panoramic-wagon and a restaurant-wagon where they serve you with throw-away dishes and cutlery. The trains seldom go full.
In the cities there are aceptable public transport, sometimes a bit confusing. Usually you pay to a box at the entrance which gives you the ticket. There are "transfer" tickets a bit more expensive and full-day tickets with a magnetic band and costing between 3 and 4 times the price of a single trip. The singe-trip is between 1,25 and 2,25USD, depending on the city.
