Work in progress…
The main place to find class 182 haulage in Germany is on route “RE1” between Brandenburg, Berlin and Frankfurt (Oder). Above is a link to a video uploaded to YouTube by Deutsche Bahn Konzern showing the process of 182 002 being wrapped in a colourful livery illustrating some of the sights to be found along the RE1 route.
The rare DB class 182 for haulage is dedicated test train machine 182 506. Previously, it carried the same livery as the passenger locos, but the above link to a video uploaded to YouTube by Deutsche Bahn Konzern shows it having a special test train livery applied.
