On the line Bonn - Euskirchen is a Talent from Bombardier (BR 644) on it´s way from Witterschlick to Bonn Duisdorf. A nice Vorsignal on the right side of the tracks. The line was two tracked until the end of the 1960´s. Twenty years later they made a test and used more trains on this line. Result: It´s now so very successfull, that they want to build up it again with two tracks.
