Q & A Case Study: NYC Subway Transportation

Case study: NYC subway design
The transportation developed new concept known as rapid transit or subway which is a public Underground Railroad usually assembled under cities to travel only inside urban areas. It carries a large group of people long distances in shorter period of times than any roadway vehicles by following shorter lines, taking underwater paths, and avoiding the overcrowded streets. The metro story initially established in London, England where millions of people lived there. Charles Pearson, who suggested to add a principal method of transportation to England, found the support from the government to develop the transportation inside the city in 1843. The construction began in 1860 and it was completed on January 1863.
The subway started its initial run at that time, under the auspices of the Interborough Rapid Transit Company (IRT), traveling nine miles through 28 stations in Manhattan. Even though Boston built their subway seven years earlier that New York City, NYC has the largest American rapid transit system in The U.S.A. At that day approximately 100,000 New Yorker tried the submerged railroad which was only in Manhattan, starting from south of the borough in City Hall heading north until Harlem station. The ticket costed a five cent coin. However, a year later the expanding reached the Bronx to have better connection outside the island. Three years later, IRT opened their lines in Brooklyn and toke another seven years to run their trains in Queens. Unfortunately, they never connected the subway lines to the fifth borough, but Staten Island has its own subway system since it is an island and it is hard and expensive to construct long tunnels underwater. In 1968, the Metropolitan Transport Authority (MTA) had the charge of running the system until today. The system has more than 25 lines scattered in the four boroughs with about 470 stations. The engineers studied the infrastructure of NYC to locate ewers, gas pipes, water mains, electric conduits, and other subsurface structures accurately to avoid any kind of accidents. They used the classic cut and
Indeed, the designer and engineers succeeded in their mention by having verity of solutions. One of the main methods is to keep the subway as close to the surface of the street as possible. This technique serve many aspects like the three objectives mentioned above. First, it decreases the distant needed to reach the subway train and then exit to streets; therefore, its handy attract the public to use this transportation. Additionally, time saving is important to the passengers, and the shorter the distance, the faster the serves. Finally, the ventilation circulation can be direct from the outdoor air though grilles in the sidewalk above without use of ducting or fans which decreases the financial budget. On the other hand, the usage of passive ventilation inside the subway cause air pollution. Since the steam and reek flow to the streets via the vents, the city get extra toxic waste that thrusts not only the passengers’ health care, but also the Pedestrians in the sidewalk, people inside the cars, and everyone uses the air conditioner (AC) inside the buildings will defiantly be affected negatively. Also, the risk of flooding, earthquakes, and other natural damages. The underground system had a threat to sink in flood water. The past applications are a must in the design these days to avoid the same mistakes and errors, but new solutions are required to be applied.
