I frequently research its unique rolling stock, its intricate infrastructure, and its demanding operations. Today, I attend school at the University of New Haven as a full-time on-campus student. I still return to my original home in New Rochelle, NY often and typically travel to Grand Central Terminal on a weekly basis. Its services are incredibly convenient and its 72-mile stretch of track touches multiple personal points of interest. Unlike most others, I understand its operations, its needs, and its future demands. I see it plagued by political corruption and fiscal irresponsibility, yet somehow it manages to transport over 110,000 people daily. Previously in 2013, I held an internship at the Maritime Aquarium in South Norwalk, CT. I would like to note that I commuted daily on the New Haven Line between South Norwalk, CT and New Rochelle, NY. During this year in particular, I saw the backbone of electric equipment transition from M-2, M-4, and M-6 to M-8, as it continues towards its final stages today. Six months into my internship, a highly advanced training project was approved and I was prestigiously awarded the opportunity to lead the project. The project involved two harbor seals, where the seals would be conditioned to differentiate and target different shapes upon verbal command. The project involved data collection, constant modifications to procedures, and a thorough analysis of the collected data. After four months of training, the seals exceeded a 90% success rate. The aquarium recognized the research as “beyond graduate level” and plans to present this research at future conventions. I am incredibly proud of this accomplishment and hope to apply my experience in research towards improving a system I hold close to my heart. At the University of New Haven, I am a second year student with 67 earned credits as of Spring 2015, placing me in the Junior Year classification. I declared a Civil Engineering major in Fall 2013 and plan to declare a Sustainable Studies and Mechanical Engineering minor by the conclusion of 2015. This year, I was hired as the Student Coordinator for a first year success program that implements an entrepreneurial mindset within the engineering curriculum. The Kern Entrepreneurial Engineering Network (KEEN) sponsors the program, and it provides funding to host monthly discussion dinners, biyearly engineering challenges, and various resources that jumpstart curiosity within its student members. Additionally, I tutor first year students in Calculus and first year engineering classes such as Intro to Engineering, Project Planning & Development, and Methods of Engineering Analysis. On the weekends, I serve as the Civil Engineering Student Ambassador and showcase the Tagliatela College of Engineering to prospective students and their families. My passion and ability to learn, adapt, and model systems, combined with the partnership of Dr. Poplawski, a globally recognized Physics expert, and joined with the cooperation of the railroad, will result in a valuable study that will predict the success of a mechanical innovation. As the New Haven Line continues to soldier into the 21st century, I hope one day to be a part of its team as a professional, practicing engineer. Daniel Delgado SURF 2015 4 Personal Statement: Nikodem Poplawski Daniel Delgado is the most passionate student I have ever known. He is extremely enthusiastic about engineering, science, mathematics, and learning. He has a strong passion for railway transportation and electric motors. As a mentor, I want to enhance this passion by developing a productive and fruitful intellectual partnership and engage him in discussions about physics. My background and expertise in theoretical physics, including analytical mechanics and electromagnetic field theory will provide him with a solid, theoretical basis of this project. I will provide him with advice, guidance, resources, and analytical skills when necessary, and will constantly and actively encourage his creativity. During the first two weeks of Summer 2015, I will be meeting with Dan to review the theoretical foundations of mechanics, focusing on the concepts from the linear and rotational motion such as velocity, acceleration, force, torque, and power. I will guide him in constructing theoretical models describing the dynamics of both traditional and linear motors, and review with him differential equations, which will be used to analyze this dynamics. I will assist him in collecting and checking the data during train trips, and guide him in formulating predictions after the data are combined with our theoretical models. At later stages of the project, I will guide Dan in analyzing the efficiency of the traditional and linear motors. I will be always available to provide constructive feedback and discuss progress. Finally, I will help him in writing a research paper and preparing a poster. After the poster presentation, I will encourage Dan to give a talk about his research at UNH. Nikodem Poplawski is interested in general relativity, analytical mechanics, and classical/quantum field theory. His research focuses on how gravity with spin and torsion can solve fundamental problems in cosmology. He proposed that torsion causes the formation of a new universe through a big bounce in every black hole and that our Universe is the interior of a black hole existing in another universe. National Geographic and Science magazines, among their top ten discoveries of 2010 listed this scenario. Dr. Poplawski also appeared in “Curiosity” on Discovery Channel, in an episode hosted by Morgan Freeman: “Parallel Universes – Are They Real?” Recently Dr. Poplawski was featured on Forbes magazine.

Currently, the rail network in the Northeast remains a critical artery of the United States. Time is money on the railroad. In fact, when the flow of transportation is interrupted, it begins to effect economic activity. Reliable acceleration is critical to preventing the disruption of a train’s time. Frequently, they are burdened with speed restrictions that disturb pace. When the seasons change, they are subject to chaotic wheel-slip conditions that create dangerous stopping conditions. The right of way between Boston and Washington DC spans 453 miles and its curves, existing infrastructure, and high traffic demands constantly bounce the trains between high speeds and restrictive speeds. In consortium with its hosting railroads, we want to determine the feasibility of optimizing the acceleration and traction performance of its electric train with the application of linear motors. Research Goal Our research question is relatively simple: “Can linear motors optimize the performance of electric trains operating on the Northeast Corridor?” We anticipate that linear technology would be more efficient than existing technology in the Northeast. If true, then it could address pressing economic need for more efficient motors to preserve the Northeast Corridor. If false, we would still have worthy data for further analysis and development of the Northeast Corridor. We recognize the value that this research project could deliver to the pursuit of personal education, the University, and the practicing engineers of the Northeast Corridor. Background In a series of magnets, an applied current can create a linear force along the length of the magnets, making a linear motor. If the magnets are arranged radially to create a disc, they create the driving force for rotation known as torque. The KONE EcoDisc inspires our model. It markets as a lineup of elevator solutions that operate with a compact rotational linear motor. Headquartered in Finland, KONE engineers were inspired by Maglev trains and developed the EcoDisc technology in 1996. Recognized for sustainability and remarkable performance, the EcoDisc is a modern day engineering success and has successfully disrupted the market competition in the elevator industry. The talk of bringing linear motors to the rails is traced back to 1905. Inventor Alfred Zehden describes an early example of feasible linear induction motors in US Patent 782312 for driving railway trains. By further researching and collecting field data, we plan to model the application of linear motor technology to railway trains running on the Northeast Corridor. Daniel Delgado SURF 2015 6 Rationale This project sheds light to a motor more efficient at accelerating, not the drastic and expensive alteration of an existing system. Additionally, linear motors are recognized for their mechanical simplicity, as they eliminate gearings and bearings. In fact, railcars can be designed and manufactured in the same traditional methods; the difference in the specification is just in the motor itself. Replacing a traditional motor with a revolutionary linear motor could potentially increase the train’s acceleration performance, reduce its mechanical complexity, and enhance the timeliness of the Northeast Corridor. We also believe that linear motors would drastically improve the train’s traction control, which in turn would reduce the amount of wheel-slip incidents, a true headache to the railroad. This study could make a 21 st century transformation possible without astronomical cost to the cash-strapped line. Focus The Northeast Corridor is home to many kinds of electric trains. Three classes of electric trains will be studied in this project. First we introduce the M-8 railcar, a multiple-unit, or “MU” railcar. Built by Kawasaki, the M-8 features a 265 HP AC electric motor on each axle and puts out 1060 horsepower (HP) per car. Kawasaki M-8 Railcar (Source: Wikipedia) Second is the ACS-64, an electric locomotive known colloquially as a “Sprinter” designed for the push-pull operation of coach cars. The Sprinters debuted last year and sport a maximum rated power of 8600 HP, which is capable of handling up to 18 coach cars. Siemens ACS-64 “Sprinters” (Source: Amtrak) Daniel Delgado SURF 2015 7 Third is the Acela trainset, built under a consortium between Bombardier and Alstom. It features two power cars at either side of six semi-permanently coupled coach cars and travels at sustained speeds of 150 MPH. Rendering of Bombardier/Alstom Acela (Source: Amtrak) The M-8 is operated by MetroNorth railroad between New Haven, CT and New York, NY, while the Sprinters and Acela are operated by Amtrak between Boston, MA and Washington DC. Methodology Experience in the field will allow us to understand the operation of existing propulsion technology. Using our observation and data, we plan to model the efficiency of the current technology to develop a hypothetical model of linear technology through fundamental principles: Design o The process of devising a system, component, or process to optimally convert resources to meet a stated objective o Applying linear motor technology to existing designs of Northeast electric trains without modifying infrastructure Mathematical Modeling o One or more mathematical relationships used to describe real world process or phenomenon o Mathematical tables and curves modeled on Excel using collected field data and theory Optimization o Use of mathematical model in conjunction with design to best solve the objective while considering constraints. o Respecting constraints, such as FRA standards, existing railroad specifications, electrical infrastructure We will analyze efficiency as a ratio of a total useful output to a total input. We will apply our obtained parameters to the laws of physics in a series of calculations. The result is a collection of curves that will predict the efficiency of a linear motor and authenticate our Daniel Delgado SURF 2015 8 model. We plan to apply the model to the three trains of focus, as their different specifications require different approaches and may result in different outcomes. We hope for the cooperation of the railroads so we can ride onboard with engineers, survey data, and observe the function of the M-8, ACS-64, and Acela. System-wide, Amtrak and MetroNorth share roughly 50 miles of track on the Northeast Corridor between New Haven and New Rochelle. However, Amtrak diverts eastwards after New Rochelle while MetroNorth heads inland to join its sister railroad, which operates on third rail. As a result, the M-8s run on both overhead wire (AC current) and third rail (DC current), while the ACS-64 and Acela travel only through overhead wire (AC). The difference in electrical configuration and infrastructure has been noted and will be accounted for during modeling. Furthermore, we recognize the importance of meeting the current FRA standards (Federal Railroad Administration) and designing around existing railroad specifications. Our final results should determine if a linear motor could efficiently accelerate a train.

As a result of increased efficiency, railways could be made a staple of sustainable transportation. In fact, the developing high-speed rail network in California could benefit from such a revolution in rail technology. Our research could be published in collaboration with the FRA for future research and development.
