Most rail vehicles have several driven axles with separate power transmission. It is often feasible to shut off some of these driven bogies during partial load and operate the remaining ones at high load. Due to the dependence of energy efficiency on operation load, such a measure increases overall energy efficiency.

Description
|
|
|
|
|
|
Most rail vehicles have several driven axles with separate power transmission. This includes both locomotives usually having a separate power train for each bogie and multiple units having several driven axles along the train. It is often feasible to shut off some of these driven bogies during partial load and operate the remaining ones at high load. Due to the fact that energy efficiency is usually lower for partial load than for maximum load, such a measure increases overall energy efficiency.
This measure requires a change of the on-board software only, since individual motor bogies always have a switch-off option for the case of failure. |
