  1. New Locomotive Developments International Rail Conference 2011 New Delhi, 28th Sept 2011 Dr. Janis Vitins, member IEEE

  2. Locomotives today cover a wide range of applications … from heavy haul, freight, passenger to very high speed 120 200 Speed (km/h) 330 Cross-border Locomotives for Freight, Regional and Intercity Heavy Haul HighSpeed TRAXX Platform IORE Kiruna S102* (330 km/h) Electric & Diesel Locomotives China S130* (250 km/h) ALP Platform China Electric, Diesel & Dual-Powered Locomotives With Dalian L.W. * With Patentes Talgo, S.A.

  3. There is a high demand for heavy haul locomotiveswhich are increasingly electric for heavy trains on high capacity corridors Example: The HXD3 locomotive • Derived from the Swedish IORE locomotive • Contract: 500 locomotives in cooperation with Dalian • Performance: • 9`600 kW at the wheels • 570 kN • 25t / axle • 120 km/h

  4. Also in India there is a large increasing need for locos… for heavy freight and passenger services; existing & new loco types New WAP-5 and WAG-9 • With state-of-the-art propulsion and controls New electric locomotives • Based on the latest developments • Increasing Railway efficiency with … • new technologies • new operational concepts

  5. Today, locomotives are typically developed as platforms ... e.g. in Europe covering different applications and requirements TRAXX AC15 and 25 kV AC TRAXX DC3 kV DC TRAXX DEdiesel-electric TRAXX MS15/25 kV AC & 1.5/3 kV DC Italy, Spain, Poland Benelux, Italy, Poland Non-electrified lines North-South corridors More than 1’600 units sold More than 1’400 units in service 5

  6. Networks .. I NL B PL D CH F L A DK S N HU … AC(15 & 25 kV) Additions DC(1.5 & 3 kV) , GPS GSM Country packages MS(AC & DC) Propulsion systems Diesel Joint basis The European TRAXX Platform has a modular structure ... to meet the needs of different countries & corridors Country equipment Speed Cargo 140 km/h InterRegio 160 km/h InterCity 200 km/h Countries Catenaries Speed

  7. A high pulling capability is key to efficient train operations… developed for the Swiss Alpine routes – and refined for other countries Sweden: 3‘300 t, 16 ‰ Lötschberg / Gotthard: 700 t, 27 ‰ Hauenstein / Bözberg: 1‘600 t, 12 ‰ Poland: 3‘600 t, 5 ‰ Single loco

  8. High adhesion is obtained with advanced control schemes… using controlled wheel slip to clean the tracks and wheels Traction motors Carbody Wheel 2 Wheel 1 Vo Push/pull rod V2 V1 TE2 TE1 Wheel slip = ΔV1 = V1-Vo Wheelbase (short) • The push/pull rod has a virtual extension to the track level in the middle of the truck.  small level of load transfer. • The adhesion control system cleans the wheels and tracks with a controlled wheel slip.  wheel surface conditioning & increase of adhesion coefficient & tractive effort • Benefit:  no tread brakes long wheel life

  9. The adhesion control is verified in many applications … allowing a locomotive design for 36 – 40% maximum adhesion Total TE of 1stbogie Total TE of 2ndbogie • Track: Borlänge to Göteborg (bad track alignment with speed restrictions) • Sanding: No • Total train load: 1’655 tons • Weather: Mixed rain and snow IORE (Sweden) Switzerland (Sweden) China (with Dalian) ALP-46A, NJ Transit (USA)

  10. Energy consumption can be reduced in three ways:1) Power regeneration, 2) Adapted driving style, 3) System design Energy savings thorough … • Regeneration of braking energy! • 10% savings on average in Germany • 20% savings on average in Sweden • Up to 30% savings in Switzerland • Adapted driving style - up to 20% savings! • Display of energy consumption to the driver • Design to high power efficiency!

  12. The dc-link of the traction converter is the central interface for electric and diesel traction, and also energy storage Electric operation Full power of 5.6 MW at the wheels. Full power regeneration at braking Diesel for Last Mile • Standard industrial engine • Stage IIIB exhaust emissions • Intelligent power control Traction converter Drive system Energy storage Battery boost

  13. The ALP-45DP locomotives for NJT and AMT … combine high power diesel & electric propulsion 13

  14. The ALP 45DP provides a one-seat ride for commuters... eliminating the need of two locomotive types and simplifying operations Key features • Operation under catenary, e.g. on the Northeast Corridor (USA), and in tunnels leading into the center of cities, e.g. Manhattan, Montreal, … • Operation with 2x 2’100 hp high speed diesel engines on non-electrified lines, e.g. in the suburbs of large cities • Energy Management: Allows to reduce fuel consumption (20-30% compared to conventional diesel locos) as well as to lower exhaust & noise emissions Misc. equipment Diesel section Driver’s cab Electric section Diesel section

  15. The TRAXX AC3 – Inauguration in May 2011... is the newest locomotive with electric, diesel and battery propulsion 15

  16. The TRAXX AC3 allows new railway logistic concepts… seamless operation into branch lines, sidings and terminals Last Mile Feature: • Full 300 kN tractive effort with electric catenary as well as with diesel engine power • Diesel engine fulfils the upcoming Stage IIIB exhaust emissions standards (required starting Jan. 2012) • Standard industrial diesel engine is used, adapted to the railway application  low life-cycle costs The Last Mile features opens the doors for new logistic concepts for freight distribution Deutz; BR 2013 4V Industrial diesel engine used in traction application

  17. New logistic concepts: The Last Mile allows to serve destinations without the need of shunting locomotives B. Last Mile operation (new) A. Hub-and-spoke system (old) Track Track Hub / terminal Non electrified siding Road Electrified line Terminal

  18. Electric and diesel locomotives in a single platform… also with the new multi-engine diesel propulsion systems E-loco 4x C18 diesels Electric powerpack • High degree of commonality • Same carbody • Same bogie, traction motor and drive system • Same driver‘s cab and desk • Same control and communication DE-loco

  19. Launch of the TRAXX multi-engine diesel locomotive with the German State Railways – 200 locomotives BR 146 BR 145 BR 185 … Previous DB fleet of TRAXX locomotives: 682 units • New diesel-electric locos for DB: • 15th April 2011: Signature for frame contract of 200 locomotives • Total contract value: approx. 600 M€ • Frame contract: 10 years • Initial contract: 20 locomotives, 1st delivery mid 2013 • Applications: passenger and freight services E 186

  20. TRAXX DE multi-engine with latest diesel technology … propulsion system with four heavy-duty industrial diesel engines Traction motors Diesel engines Alternators Converter M 3 ~ AS PM3 ~ Bogie 1 3 ~ M 3 ~ AS PM3 ~ M 3 ~ AS Bogie 2 3 ~ PM3 ~ M 3 ~ AS 3 ~ PM3 ~ Auxiliary supply Braking resistor Train line supply 2 ~

  21. Industrial engines fulfill stringent exhaust emission standards much more easily than large engines Exhaust emission limits for Europe & North America Tier 0 Tier 1 When Rail needs the technology, it is already in operation in the industrial sector UIC II Railway diesel engines Stage IIIA Particulate [g/kWh] Tier 2 Tier 3 Euro 3 Industrial diesel engines Tier 4 Stage IIIB Euro 4 Euro 5 Stage IV Stage V Euro 6 Today

  22. Summary • New state-of-the-art locomotive technologies allow to … • Increase train loads - with advanced adhesion control • Reduce energy consumption substantially • Reduce the ecological foot-print • Develop modular locomotive platforms – reducing overall operational costs to the railways • Increased railway efficiency is obtained by integrating electric and diesel traction … • As with the dual-powered locomotive ALP-45DP • As with the TRAXX AC3 with Last Mile reducing the need of shunting locomotives allowing new logistic concepts in freight distribution • Technologies are global • Allowing the Indian Railways to benefit from state-of-the-art locomotive technologies
