This will be the first in a series of articles about my process of building a LEGO steam locomotive. I intend to cover a variety of topics in this series including research, the use of custom elements, aftermarket electrical devices, and building techniques. While I will focus on a specific locomotive project I am currently working on, this series will not include a full set of step-by-step instructions to that locomotive. My intention is to share some experiences and techniques that I hope people can apply to any steam locomotive project, and perhaps other types of LEGO models as well. At any rate, my designs are usually pretty fragile and don’t really lend themselves to redistribution via instructions. Instead, I will lay out my approach to building a steam locomotive and why I think it is effective. I hope that this will help people who are struggling with what I think is a particularly difficult type of model to build or, at least, be of some interest to the readers of this site.
