How to Make Mountains and Hills for Your Model Railroad by Doug Anderson
[Jan 26, 2008]
Once you've got a train layout set up on a flat table, you might want to make it more interesting by adding some mountains and hills. There are a couple of ways to do this, and they are both easy.
Papier-Mâché Method
If your layout is temporary, or you don't want to spend much money, you can use the papier-mâché method. Basically, you just scrunch up some newspapers into the general shape of the hill or mountain, then cover them with sheets of newspaper dipped in papier-mâché paste.
The traditional method of making papier-mâché paste is to add one part water to one part flour. Some people prefer to boil the paste, saying that it makes the consistency smoother. Water to flour ratio is changed to five parts water to one part flour in this case. Other people use a three to one or a one to one ratio of water and polyvinyl acetate wood glue. Still others say that starch makes a fine paste. Adding a dash of cinnamon to the mixture gives the paste a pleasant smell; adding a dash of salt and sugar reduces the chances of the product developing mould.
You simply dip sheets of newspaper (fold them a couple of times to make them thicker) in the paste and drape them over the scrunched up newspapers. The sheets will be soft and pliable, so mould them into hills and valleys as you like. Let the papier-mâché dry overnight. You will find that it is hard and rigid, like a piñata.
