Abstract [en]

In many studies efforts are made to

decrease the energy consumption of

trains by optimizing their drive

style, e.g. accelerate and brake

optimally and regenerate electricity

when braking. In other studies the

goal is to distribute the run time

between stations in an optimal way to

decrease the energy consumption, given

a relatively simple drive style. In

this report the goal is to combine

these two energy saving methods to

obtain as low energy consumption as

possible. By coupling one software

containing a drive style optimizer

with another software which by

different optimization methods

calculates the optimal run time

distribution on a given track this is

accomplished. The study also contains

a comparison between drive styles,

with the goal to find a relatively

simple but energy efficient drive

style. Finally the dependence between

run time distribution and energy

consumption is further analysed.

The results show that by

redistributing the run times the

energy consumption can be decreased

compared to previously existing time

tables. They also show that a

relatively simple drive style gives

comparable energy consumption compared

to the one obtained using a drive

style optimizer. Finally the results

show that the dependence between run

time and energy consumption can be

approximated with a simple second

order equation.
