Hello, I am in the planning stage of building a diorama involving a New York City R27 subway train.
The dimensions of each train car would be 6 feet long and 1 foot wide and high. I was thinking of using some type of plaster. Once I create a mold of a side of the train, I could fabricate the cars fairly quickly. Also, I thought about clay; the problem is I would need a type which wouldn't require a kiln for drying.
I would appreciate any suggestions, thank you in advance.
