Even in the EU, you will want an engine in front and you'll want the train to be coulpled together. For one, the engine is the place where the train understands the gazillion signaling systems in the EU, and it's where the overhead power is converted to on train power. Both items cost like millions, it's not something you want to distribute.

perhaps automatic couplers and a power pack on each truck (bogie) will allow automatic shunting, which is the newtec gimmick that can make freight trains competitive again.
