This item is produced by Hobbytrain of Germany and represents a tamping machine.

The markings on it, do indicate that it is of German origin, but a little touch with a paint brush will obscure the DB logo and it will not look out of place on a modern-image layout.

 

The box shows the item to be a "Gleisstopfmaschine Plasser Duomatic 07-32"

 

This is a motorised unit and runs on its own.

 

When I get my camera back I will show a photo of it.
