2 Desiro EcoTrain VT 642 modernization Development of an innovative technology platform Hybrid control Batteries Brakes Bogie Motor control and gearbox Diesel-electrical drive unit Introduction of hybrid technology serial, diesel-electrical drive unit Adaptation of bogie construction and bogie equipment Installation of Lithium-ion batteries and super caps Development of intelligent hybrid control unit Modernization of HVAC system Electrification of auxiliary units Modernization and adaptation of brake system 2

3 Desiro EcoTrain VT 642 modernization Scope of Knorr-Bremse Brake Panel modernization Brake Control Unit modernization Wheel Slide Protection modernization Introduction of dynamic brake control (brake force distribution) Introduction of actual blending for battery charging (blending with actual dynamic force feedback) Up to 35% 3

4 Driver Advisory System icom Assist (LEADER) Installation of icom Assist in existing or new trains and locomotives Benefits of icom Assist Improved punctuality Improved energy efficiency Wear reduction Reference project 300 DB Cargo locomotives (option +600) Risk sharing through performance based pricing Return of investments in less than 2 years Up to 10% 4

5 IFE Doors Train modernizations Replacement of pneumatic door drives by electrical ones Metro fleets (Switzerland, Turkey, Hungary, etc.) Refurbishment Regional trains such as DB double decker Modernization LRV such as Munich tramway Modernization Altogether more than 3000 doors modernized * Up to 74% * calculation bases on following assumptions: cycles per year, 5000h annual operation, standard regional train door application 5

6 IFE Doors Train modernizations Replacement of pneumatic door drives by electrical ones Real benefits of electrical doors over pneumatic doors No need of high quality air for doors operation No need of car-body pneumatics Improved availability Improved comfort for the passengers Improved safety due to pinch protection Improved diagnostics due to electronics Reduction of maintenance costs Weight reduction ~15% 6

7 Modernization of auxiliary converters PowerTech LITE Usage of Light Integrated Train Energy technology Integration of APS, HVAC and ASU Elimination of duplicated modules Reduction of complexity Great in combination with VVVF 750 V DC / 1500 V DC APS Benefits of LITE technology Potential weight reduction by 20% Potential material cost reduction by 10% HVAC HVAC 3 AC 400 V / 50 Hz DC 680 V 50 Hz ASU HVAC HVAC 50 Hz kwh/year/coach 7

8 Modernization of auxiliary converters SiC Usage of Silicon Carbide (SiC) technology Introduction of new SiC technology for MOSFETs and diodes First auxiliary power supply prototype for LRV in 2017 Benefits of SiC over silicon based technology 8x higher switching frequencies lead to smaller magnetic components Higher breakdown voltage Better thermal management Potential converter weight reduction by ~20% Potential converter size reduction by ~20% Copyright, Cree Inc. Currently up to 3% as current focus lays on weight and size optimization 8

9 MERAK HVAC VVVF Usage of Variable Voltage Variable Frequency technology PowerTech inverter Variable frequency compressor 8 high speed trains with 32 HVAC units go in operation in Norway in 2018 Benefits of HVACs with VVVF technology Improved coach temperature control Weight and size reductions Compressor switching cycle reduction Improved compressor lifetime Up to 5000kWh/year/coach 9

10 MERAK HVAC Adaptive load control Control of fresh air supply, depending on passenger load Reduced fresh air Reference projects Decreased number of passengers ~50 ZEFIRO high speed trains in Italy ~40 HARAMAIN high speed trains in Saudi Arabia ~20 FERTAGUS commuter trains in Portugal Refurbishment ~250 metro trains in Sweden - Refurbishment Up to 10000kWh/year/coach 10

11 MERAK HVAC Heat pump Usage of heat pump instead of electrical resistor heating Heating Heat pump Environment Electric Heating Benefits of HVAC heat pump functionality Major reduction of pre-heating time Minor impact on size and weight of the system Up to 13000kWh/year/coach 11
