I/ INTRODUCTION New York is growing much faster than many could predict. One of the biggest challenges that face New York City is public transportation. Roads along cannot do the job. Neither can the subway alone. However, subway is the only proven alternative that gets cars of the road while providing reliable transportation. The subway will help families save money. Everyone desires to save money, especially when money is already a tight. Families that now need two cars could get by with only one. Depending on the individual’s situation, one parent could use the subway and the other drive to work. Or the whole family could take subway by walking to the subway station. This is not only saves families money, but also individuals will save money. With subway, many will not need to put in 50 dollars worth of gas in week. Instead, they could use that money towards schooling or groceries. Finally, the subway is the best alternative at reversing air pollution. The majority of air population in New York City is caused by gasoline-burning vehicles. This is the reason why we have ozone action days. Electric powered subway rail systems provide a proven alternative to the automobile. Results around the nation, including those in New York City, show that rail gets more people out of their cars than any other alternative. If we are able to get people out of the cars and onto subway, we will be reducing air pollution tremendously. Because of this, the MTA issued the fund to extend the Number 7 Line further to the West side. This new extension of the Number 7 Line will result in the merging of the old and the new, allowing passengers to transfer to other lines quickly and easily. Number 7 line will provide access to the Jacob Javits Convention Center, and hopefully may provide future service north and south with access from Hell’s Kitchen to the Battery. The Number 7 Line is a key component of the plan to develop Manhattan’s west side which is expected to experience tremendous growth. II/ HISTORY: The New York City elevated subway system started as a private operation under contract to the City shortly after the American Civil War using steam locomotives. As the city grew through consolidations, this arrangement was no longer feasible as no private company was capable of funding the growing system. By issuing bonds for a subway and through arrangements with the current operators of the elevated transit, plans were made to eliminate the steam trains and go underground using an electrified system. The system was to utilize direct current for the trains and alternating current for all other electrical requirements. Presently, all the electrical current comes in AC and is converted to 600 volts DC. In 1940, the City of New York created the Metropolitan Transportation Authority and
