The upgraded line Cologne-Düren (ABS 4) seen from the eastern end of the northern platform at Köln-Ehrenfeld on 15 February 2003. The tracks 3 (right) and 4 (left) next to the platform are used for regional and long distance passenger trains. Further right is track 2 for the S-Bahn (urban trains), track 1 is still missing. Track 5 and 6 for freight trains on the left join in the background, as the still uncompleted bridge at the Subbelrather street allows only four tracks there. The orange boards are Lf6 signals, they announce permanent speed restrictions of 70 km/h at track 3 and 120 km/h at track 4. The yellow board at track 4 is an Lf1 which announces a temporary speed restriction of 50 km/h. There is a similar one at track 3, but it is covered by the Lf6. In track 4 the cable of the LZB (Linienzugbeeinflussung) is visible, it is also present in track 3, but not yet in service. The five signals are the exit signals, they are called P2 to P6 (from right to left).
