|Subject: U.S. transportation network|
I have a question about railroads and buses in the U.S.
(and in other countries.)
I'd like to know about the railroad network in the U.S. Does anyone know web sites which shows the railway network all over the U.S.?
Next, I'd like to ask about buses. In Japan, most cities are connected also by high-way bus network. They are cheaper than trains or airplanes, and are popular among young people. In the U.S. (or in other countries), are buses used as long-distant transportation?
I hope some of you tell me about these questions. Takeru, Tokyo.
