http://www.modelbuildings.org Watch this short video showing how to build a station platform for a model railroad layout. This video shows construction of a small train station platform and the building of a large platform for a bigger train station on a model railroad layout. The building process uses old cereal packs, but you can use foam core or core flute sheets instead. All methods are easy and inexpensive.
So, if you want some train platforms for your model railroad I hope this gives you some ideas. Enjoy!
