In 1984 the trains were painted in a silvery color, which resulted in the nickname "Sølvpilen" (Silver arrow).

In 1990 these trains were phased out from Danish service and donated to a Polish railway (first private in Poland - Lubuska Kolej Regionalna Spółka z o.o.).

This "Alpen-See-Express" ran scheduled from Hamburg and Dortmund to southern German and Austrian destinations, including Berchtesgaden, Lindau, Oberstdorf, Innsbruck, Zell am See, and Salzburg.

One of the 10-unit trains was loaned from Italy to the East German Reichsbahn (DR) and served from July 27, 1990, to September 29, 1990, as InterCity Max Liebermann on the route Hamburg–Berlin.

[20] In order to run ten-unit trains with a maximum speed of 160 km/h, four VT 11.5 were rebuilt in 1970 and received 2,200-horsepower (1,600 kW) AVCO Lycoming TF55 gas turbines supplied under license by Klöckner-Humboldt-Deutz in place of their original 1,100-horsepower (820 kW) Diesel engines.

012, 003, 007 and 010, respectively),[1] recognizable at the large dimensioned air intakes, and used for DB InterCity service, starting with the train connection between Hamburg and Ludwigshafen in July 1974.

From 1975, a mixed operation with diesel and gas turbine power heads was made possible.

Since the turbines caused some problems and had higher fuel consumption, the 602, like the DB Class 210, were taken out of service by 1979.
