Only one locomotive is actually pulling the train, because two 1600's cannot work together on one train. There is a risk that they interfere with the signalling. At the border they will be changed for German locomotives, because the current on the overhead wires is different in each European country.

Three locomotives not only gives you more power, but you can also divide the pulling force over more axles, which reduces the chance of slipping.
