I live in Utah and I was so excited when we started to get trains here. We now have LR transit and commuter rail. I would like to start a layout of my city. I have done a lot of thinking and looking into how to build custom models of the buildings in the city. The problem I am running into is that in HO, blocks are ~9 feet long! and in N scale, they are ~5 feet. It is not practical to build exactly to scale. How do you choose what to shrink down and by how much? Any suggestions on building city layouts?
