  1. CE 515 Railroad Engineering The Future “Transportation exists to conquer space and time -”

  2. High Speed Rail • United States 2030 Plan Courtesy of http://www.ushsr.com/

  3. High Speed Rail • Foreign companies bring technology and production to the US. • Spain – Talgo in Wisconsin • www.talgoamerica.com • Germany – Siemens in California • www.kaisersmith.net • France – Alstom in New York • www.alstom.com

  4. High Speed Rail Technology • Japanese Shinkansen system is engineered for earthquakes. • Keystone of High Speed Rail: Safety & Environment. Dr. Norimichi Kumagai.

  5. Amtrak • Has it’s time come? • Funding • www.amtrak.com • Cooperation with freight railroads • Redundancy of lines with new HSR networks

  6. Capacity & Infrastructure • How can we grow to ensure sufficient capacity exists? • Hard due to cost per mile to build, common estimates are 5-50 million. • Acquisition of right of way • Environmental concerns • Raw materials • Railroads may not be able to keep up with growth by themselves.

  7. Capacity & Infrastructure • Cambridge Systematics 2006 Study on capacity.

  8. Capacity & Infrastructure • Cambridge Systematics 2006 Study on capacity.

  9. Diesel Electric Technology • Genset switching locomotives • Reduce emissions: 80% of NO & PM • Operates with 3 diesel engines, but only ones it needs • Or operates on a bank of lead batteries • Courtesy of www.ecollo.com • Natural Gas Locomotives • 1980 ‘s & 1990’s Technology • Dual-Mode Locomotives • Operate on Diesel-Electric power, and another; Electric or battery, or natural gas • Courtesy of www.energyconversions.com • Courtesy of www.philadelphiaspeaks.com • Possibilities?

  10. Reregulation • Shippers and customers are lobbying for: • New controls on railroad rates and profits. • Service levels on “common carrier” scale. • Railroads argue: • Will result in reduced profits, therefore reduced service. • Will cut into the ability to increase capacity. • Will obligate railroads to provide unprofitable services.

  11. Nationalization • Most countries have a nationalized rail system • Benefits if done correctly: • Establishes a cohesive control and plan for development • State funding as a public service will ensure supply and demand is balanced. • Can better focus needs resulting in domestic industry • Can make more money available for capital investments • Criticisms if not done correctly: • Bureaucracy may result in slower administration and innovation • State funding may focus on “profitability”, which stifles investment • Can lead to smaller base of rail domestic industry

  12. Trains Magazine View on Future “6 high-tech advances.” Trains Nov. 2008 • 1. Electronically-controlled pneumatic brakes [ECP] • Air hose & electrical connection between cars • Can trigger brakes almost instantaneously • Increases in reaction time = short stopping distances = shorter headways = more capacity

  13. Trains Magazine View on Future • 2. Positive Train Control [PTC] • Now is written in law for complete use by 2015 • Allows check, engineer of PTC, PTC of engineer • Maximize fuel efficiency = lower costs • Increases in reaction time = short stopping distances = shorter headways = more capacity “…Transportation Technology Center Inc – believes a 20% improvement in asset utilization is possible”

  14. Trains Magazine View on Future • 3. Remote control locomotives • Currently in use in yards and switching • Could be like “fly-by-wire” aircraft systems • Could allow “monitoring” rather than “operating • Better fuel use = lower costs www.Directindustry.com

  15. Trains Magazine View on Future • 4. Digital inspection technologies • Truck Performance Detectors • Wheel-Impact Load Detectors • Safety Appliance Inspection System • Use of high speed cameras to inspect trains with database storage. • Laser-acoustic rail-flaw detection • Monitors at faster speed than rail inspection cars

  16. Trains Magazine View on Future • 5. Electrification • Factors include: • Fuel Costs • Clean Air Mandates • Greater train frequency • HSR • Synergies of technologies, PTC + ECP + E = > Capacity www.Northeast.railfan.com

  17. Trains Magazine View on Future • 6. Nanotechnology • Wireless sensors can be used in “lubricants to rails” • Will alert personnel of imminent failures like: • Longitudinal stresses • Heat kinks • Accident reports tionanostructure.wordpress.com
