Abstract(s)
Trains and railways are influence our lives in a variety of ways we may not always realize. Passengers traveling across country get their destination safely and quickly with the use of trains and railway systems. Urban cities came up with importance of railways and railway stations in particular.
Moreover, unlike other industries which become modern over a period of time, railways changed technology at a much faster scale. It bought distant towns closer to mainstream cities and helped big time in commerce. Railways were the first form of rapid land transportation and had an effective monopoly on passenger traffic until the development of the motor car and airliners in the early-mid 20th century. In addition to that, mankind nowadays largely depending on railways mainly because it offers more safe, comfortable and cheaper transportation.
The main aim of this project is, to give detailed information about present-day railway systems as well as the reason behind the paradigm shift from Diesel Locomotive to Energy Traction system. Along with, the involvement of power equipment for transferring energy from the National Grid to the Pantograph (Mechanical Part of Train, which ensures the connection between Contact Wire and the Train), followed by, the Maintenance actions taking to account to keep Portugal Railway system more functional, then describes the main case studies associated with this electrically operated railway system and the developed solutions based on the requirements of the company.
