Map a on this webpage shows a land use model for the railroad age. explain how this model is similar to the von thunen model, and describe the assumptions the new map makes about transportation and land use. (site 1)

The Von Thunen model has an epicenter which is the center of a settlement. The model shown has a center area and grows outward just like the Von Thunen model. All the important goods are closer together while the forest and non important goods are farther outward. The new map makes the assumptions of goods are carried out by railroads and the climate and soil quality are the same throughout the map but may vary depending on specific areas very much like the Von Thunen Model. 

Hope this helps. I'm on this question too so I could be wrong but at least I tried.
