It’s almost unprecedented for a class of locos to remain in express passenger service 60 years after it was introduced but that’s what DB’s Class 115s, better known as 110s or E10s, have achieved. Most were displaced by Class 101s and ICEs by the late 1990s but they never quite disappeared completely and, even in 2017, two different 115s were seen on Stuttgart - Zürich IC services.
115.509 accelerated IC 281, the 16:29 from Stuttgart, away from Rottweil on 29 April 2017. It’s just a shame it doesn’t have a more attractive livery.
