This is a NG (500 or 600 mm) train on "temporary" track laid to clear rubble from a destroyed German city center. Many cities used the debris to build memorial parks of the war. In Stuttgart it was taken to the highest hill in the city and the height was extended by 40 meters.

The cars are known as V-tippers and multiple versions are available in all scales, from Nn3 to G. Below is a Nn3 body produced by 3D printing on a quarter.



Based on the engine, I think this next photo is from the U.K. This is as simple as a NG railroad can get. A guy takes the tipper to the clay pit, changes vehicles and dumps a load of clay into the wagon, and then brings it back to the brickworks.



Lastly, we have a poor image of a tipper dumping clay at a flooded British brickworks.

That shovel and train would make a super mini-diorama.

I wonder if there are plans to make European street car models for dioramaists to put in their battle scenes?

Fred - there is a well-known diorama of a bombed urban bridge (over a street) with a wrecked streetcar. As I recall, the guy "split" the car in the middle to make it look like two. I forget what he used. If it helps you think of it, there is a gas-masked mother pushing a pram under the bridge - I've seen the Berlin proto photo (ruined movie theater in the background) that must have inspired that. I think I have a photo of the dio if you don't know it - which would surprise me ;-)
