Ahoi! Participated to the development of a simulation tool for that purpose. Many factors need to be taken into account:
- The gradients of the track
- How agressively you want to drive at different time of the day
- How many trains
- The timing of the trains.
When one train brakes, it can power another one that accelerates at the same moment
- The efficiency of the power chain
- The resistance model of the train
With so many parameters the results can be quite volatile.
However, rule of the thumb in the business is that 30% saving can be achieved with good energy management. Hope this clarifies a little.
