RAILWAY PASSENGER TERMINALS Most large passenger stations are popularly referred to as "ter minals," even though, strictly speaking, they actually are not ter minals, that is, the end or terminus of the railroad. Specifically, a passenger station consists of the group of tracks, platforms, build ings, etc., which furnish the means of contact between the railroad and the public for the purposes of travel. Where more than one railroad is so served the term "union station" is often used. In addition to the building for the waiting room and other station facilities, the platforms also are housed. This housing in many earlier stations was a high shed covering both tracks and plat forms. Later this type was practically abandoned in favour of a low shed over each platform. Many large passenger stations are constructed in combination with office buildings or hotels—an arrangement which increases the station's concession business.
loop principle is applied must handle a mixture of suburban and through traffic, the composite type which is a combination of the stub and through, is used. The suburban part of the traffic is handled around the loop and the through traffic largely on stub tracks. Where suburban and through traffic are handled together, and the suburban business is large, there is a tendency to handicap seriously the through traffic; this fact suggests the desirability of their segregation either in the same or separate stations.
Types resulting from the topography or the relative levels of the track and streets, are : Single Level.—This type, representa tive of the early stations built when low costs were vital and grade crossings permissible, has the tracks and adjoining streets at the same level. Double Level.—This type has the tracks and adjoining streets at different levels. The gradual elimination of grade crossings increases the number of this type. The better ar rangement is afforded with the streets below rather than above the track level. Multi-level.—The multi-level type is a combination of three or more levels and usually results either from the topog raphy or from the area available being limited by physical con ditions or high land values. This type lends itself to the segrega tion of suburban traffic.
The types based on the arrangement of the principal station facilities are :—Waiting Room Type.—A general waiting room is made the focus of the station traffic, the major facilities opening therefrom. Concourse Type.—A general concourse is made the focus of the station traffic and facilities, the ticket offices, train gates and major facilities opening therefrom. Composite Type.— A service lobby is provided for sale of tickets, checking baggage, etc., with waiting rooms and passenger train concourse separate therefrom.
