Virtually coupled trains |
 |
evaluated |

|
|
| Based on the concept of self-propelled freight cars, a new method of train formation has been proposed: virtually coupled trains. The concept is based on the idea of using modern electronics and data transmission to run several self-propelled units one behind the other without physical contact but at distances as short as mechanically coupled cars.

Energy efficiency potential of virtual train coupling obviously depends on the point of reference. Compared to loco-hauled mechanically coupled trains, virtual coupling will be less rather than more energy efficient. However compared to self-propelled freight cars running separately, virtual coupled trains will have much better aerodynamic behaviour. The quantification of this effect depends on many parameters and is not possible in a general manner. |
