It looks like Marx is going for a Sunday drive. According to SPIEGEL ONLINE:
Berlin’s Marx-Engels monument near the Alexanderplatz square is being moved because of construction work on a new subway line. This photo shows the sculpture of Marx being loaded on a truck to join Engels in a new position. Berlin’s iconic TV Tower can be seen in the background. The sculptures of the founders of modern socialism Karl Marx (1818-1883) and Friedrich Engels (1820-1895) were made by German artist Ludwig Engelhart and unveiled in 1986.
