In the early days train stations were often equipped with facilities for both passengers and goods. Many railway lines were goods-only or passenger-only. Thus, if a line was dual-purpose, there would often be a cargos depot apart from the passenger station.
Dual-purpose stations can still be found today in some places. However, in many cases goods facilities are restricted to major stations.
In rural and remote communities across Canada, Britain and the United States for example, passengers wishing to board the train had to flag the train down in order for it to stop. Such stations were referred as "flag stops" or "flag stations".
Most stations date back to the 19th century and represent the great architecture of the time, giving the city and railway operations prestige. Countries, where railways arrived later can still possess such architecture. These stations often imitated styles from the 19th century.
In constructing a station, various forms of architecture were used. From the grand, intricate, Baroque or Gothic-style buildings to the plain utilitarian or modernist styles. Train stations in Europe appeared to follow British designs. In some countries, like Italy, the train station is financed by British railway companies.
Stations built more recently often have a similar feel to airports, with a simple, abstract style. Examples of modern stations include those on newer high-speed rail networks, such as the Shinkansen in Japan, TGV lines in France and ICE lines in Germany.
Whatever design of the terminal building, the connections from the terminal may be made available to intersecting rail lines or other transport modes such as buses and taxis. This is for the ease of passenger mobility and accessibility to the final destination.
