472.003 crossed over the top of the tunnel exit just north of Hamburg Hbf as it approached with an S11 service on the afternoon of 1 October 2015. Train 47375 was the 15:17 from Hamburg-Altona to Barmbek. Very few trains approaching from Dammtor seemed to take the line over the top of the tunnel into platform 3 at the Hauptbahnhof and this was the only one that I saw in over an hour.
