grabcad

In this model, there is a vertical bridge which automatically or even can be manually be turned horizontal with the help of power driven motors. This will be helpful for easy crossing of the tracks. If you watch closer there is another thing at top of each coach, it's a fan. We know that there is a lot of kinetic energy in the air that crosses by the train and if we can utilize it then we will have enough more energy for the individual coaches.
