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.
Union Pacific heritage, MoPac locomotive by Andrew Mollmann
In 2005 and 2006, the Union Pacific unveiled a new set of six, EMD SD70ACe locomotives in unique heritage paint schemes, honoring the railroads acquired by UP since the 1980s. The engine numbers reflect the year that the predecessor railroad was absorbed into Union Pacific. The locomotives commemorate the Missouri Pacific with UP 1982, the Western Pacific with UP 1983, the Missouri-Kansas-Texas with UP 1988, the Chicago and North Western with UP 1995, the Southern Pacific with UP 1996, and the Denver and Rio Grande Western with UP 1989.
