Goal: 5 to 10% consumption reduction
|

 |
CORYS T.E.S.S. offers railway operators (passengers or freight trains) a 5 to 10 percent reduction in their energy bills with Golden Run, its eco-driving algorithm.
This model was validated on both driving simulators with a high level of detail and during on-board tests on main lines. Starting with constraints like time cards, operating rules and towing force limits, it calculates a speed profile corresponding to a minimum energy consumption.

Golden Run can be used in three ways: |
|
|
independently for energy efficient timetabling and train composition optimization |
|
|
on-board a locomotive equipped with a GPS to advise the driver in real time |
|
|
integrated into a driving simulator: the student is informed in real time of the train's energy consumption and, at the end of the session, compares it with that of optimal routes. |
|
|
Practical Case:
Golden Run was used in the United States following temporary speed restrictions, for timetable optimization of an atypical passenger line (from 1,450m to 250m in altitude).
The study demonstrated the possibility of reducing energy consumption by 5 to 10% by simply delaying a stop by ten minutes.
