Facilities on the Mass Rapid Transit (Singapore)
Some MRT 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 a few possess 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. SPH Media Trust's The New Paper is distributed at most stations every weekday morning and Saturdays. Wireless @ SG is also deployed at many of the stations including some in the North East, Circle and Downtown lines. Buskers were deployed to various crowded MRT stations in order to ease overcrowding on the MRT, which  has been started at City Hall and Raffles Place during the mornings. Escalator announcements were also put up in Simei and Tanjong Pagar, and charging points were put up at City Hall and Kent Ridge.
