Thanks Chris and Mike,
the locomotives were used for transport in the factories. They are standing with the ships in the old harbor. Everything is freely accessible.
The red steam engine is on the grounds of the technical university and the brown steam engine is at a beer garden.
Magdeburg was a large industrial city until the iron curtain was opened in 1990.
There isn't much left of it now.
Except for a few relics.
Michael
