Four engines

For americans, four engines isn't that much, but you don't see that often in Germany, or for that matter, Belgium, which is depicted here. A german "Ludmilla" (built in Russia) is driving together with three belgian class 77s (built in Germany). Why this train needs four engines is a little beyond me, as it wasn't exactly very long. I also cannot say for certain which of these engines was actually running. My first guess, that the belgian engines were new ones delivered, proved wrong: According to Wikipedia, they were all delivered ending in 2006.
