I am interested in starting back into model railroading, however I have very limited space, so Z is very appealing to me. My biggest question is since I do not have a permenant place for a setup, is it possible to create a layout that is more than just a simple loop on a small table without fasting the tracks to the table? I would like to be able to setup and take apart the setup when ever I need the space, plus it gives me the flexibility to try new things. My second question is if anyone has any recommendations for a good startup kit. I do not want to invest a whole lot of money into this until I give it a try.
