1. How It Works Diesel Locomotive Air Breaking Dynamic Breaking

2. Power Generation  Diesel gas is the energy source

3. Power Generation  Diesel gas is the energy source  Gas fuels the engine

4. Power Generation  Diesel gas is the energy source  Gas fuels the engine  The engine turns the generator  The generator produces electricity

5. Power Generation  Diesel gas is the energy source  Gas fuels the engine  The engine turns the generator  The generator produces electricity  The electricity turns the motors in the trucks

6. Air Breaking  Engine drives an air compress

7. Air Breaking  Engine drives an air compress  Air compressor fills an air tank  Air tank supplies pressure to every car in the train  Air pressure keeps break shoes from touching wheels

8. Air Breaking

9. Dynamic Breaking  Electric is no longer routed to motors  Traction motors act like electrical generators

10. Dynamic Breaking  Electric is no longer routed to motors  Traction motors act like electrical generators  Electricity turned to heat in the brake grid

11. Dynamic Breaking  Electric is no longer routed to motors  Traction motors act like electrical generators  Electricity turned to heat in the brake grid  Fan removes heat from locomotive
