The Mass Rapid Transit system is the rapid transit system in Singapore. ==Station layout== MRT stations are either above-ground or underground, or just below ground level (in the case of the North-South Line side of Bishan MRT Station). Stations have two classifications of areas, ''paid'' and ''unpaid'' areas, which allow the rail operators to collect fares by restricting entry between the areas only through the fare gates, also known as ''access control gates''. Commuters enter the paid area in order to board a train; and must enter the unpaid area in order to access the street, and must pass through the gates. These gates, connected to a computer network, are capable of reading and updating electronic tickets capable of storing data, and can store information such as the initial and destination stations and the duration for each trip. Fares are collected on the basis of this information. A typical station has a concourse level and one or more platform levels. The concourse level consists of the ticketing machines and the access control gates between the paid and unpaid areas. Tickets are presented at these gates in order to pass between the unpaid and paid areas. Escalators and stairs providing access to the platform level are located only within the paid area. The platform level is where passengers board and alight from the trains. Most of the time this consists of one actual platform island with two sets of tracks for opposite directions running on either side. Except for Changi Airport Station, the concourse level and the platform levels are separate levels. Escalators and stairs between the concourse and platform levels, as well as the concourse level to the street level if necessary. Most stations have only one platform level. However, cross-platform interchange stations have two or more platform levels, one for each train line. These extra levels, together with the linkways connecting between them, make interchange stations to have more levels than a typical station that serves only one line. In above-ground stations where trains run on viaducts, the concourse level can be either located on the ground level or on the second level, with the platform level above it. When the concourse level is on the second level, a pedestrian overpass may sometimes link the unpaid area of this level to another prominent building nearby, such as a polytechnic. In underground stations, the concourse level is typically an underground level, with the platform levels below it. For most underground stations where the concourse level is underground, there will be pedestrian underpasses that lead to street access on top of the station area or basement levels of neighbouring buildings, such as a shopping centre. Some stations, particularly interchange stations, are deep enough to be shielded from conventional bomb attacks from the air and act as bomb shelters. This status is enhanced by the fact that underground MRT systems have prebuilt ventilation systems with air-conditioning to ensure a degree of comfort in the unlikely event of a conventional air assault. Most stations have island platforms, although Braddell MRT Station and Dover MRT Station have side platforms. This is because island platforms are seen to be less costly than side platforms, or possibly to make it convenient for passengers to transfer to another train on the same line but running in the opposite direction. Also, all stations are made to be as straight as possible because the degree that trains would turn at when approaching and leaving a station would be too great if curved stations were built. A good example of this engineering defect is seen at Mong Kok East Station in Hong Kong, where Platform 1 of this station (to the left if travelling to the Hong Kong-China border) is curved and the gaps are wide. Trains also risk being scratched depending on how it enters the station. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Facilities on the Mass Rapid Transit (Singapore)」の詳細全文を読む スポンサード リンク
