It been a while since we’ve seen a big articulated steam locomotive from LEGO® train builder Anthony Sava. But the wait is over as Anthony’s long planed model of the Duluth, Missabe, & Iron Range class M4 “Yellowstone” is finally completed.

I love coming across new (or maybe just new to me) train builders when perusing through flickr, or one of the other LEGO® train hangouts online. Especially when their models are as good as these two by Aaron Burnett.
It’s been several weeks since I’ve updated the Matson’s Landing in L-Gauge series. In all openness, there hasn’t been a lot of progress. I find that, from time to time, I need to take a break from a project and come back to it with fresh eyes at a later time. I was running into some design issues with the Matson’s Landing locomotive, so I moved on to other projects. This week I returned to this locomotive, and find myself energized to work on it again.
In my last article on the design, I promised to document the main drive system for the Climax logging locomotive that I’m building. First, though, for the beginners, a quick run-down of the LEGO Power Functions technology that I’m using.
The Power Functions (PF) system was released back in 2007, at about the same time that the LEGO 9v and RC train systems were discontinued. Power Functions elements were designed to be used cross-theme, with elements showing up in both Technic and Train sets. The first official Power Functions compatible train was the Emerald Night (10194), released in 2009.
At its most basic, a PF system consists of a battery box connected to a motor. The battery box has an on/off switch, which sends or cuts power to the motor. There are a few different types of battery boxes available. For our purposes, we’ll use the box with a 4 x 8 stud footprint.
The next step up from the basic box/motor setup is the Rechargeable Battery Box (8878) (http://brickset.com/sets/8878-1/Rechargeable-Battery-Box), connected to a motor. The rechargeable box, in addition to the lithium polymer battery, has a small speed-control dial built into the top of the box. With this, you can set or change the speed of the motor. This is good for models that stay in one place, but difficult to use for models that will vary their speed and direction often.
To gain more control over a model, an Infrared Receiver (8884) (http://brickset.com/sets/8884-1/IR-Receiver) and Remote Control (8885) (http://brickset.com/sets/8885-1/IR-Remote-Control) can be added. The receiver will pick up signals from the controller, then send the information along to one or more motors. The IR Receiver can pick up signals over 4 channels on two ports, allowing up to 8 motors or other outputs to be controlled. The basic controller allows for forward/stop/reverse movement, which must be monitored by the user.
Another step up, and what most brick train builders use, is to swap out the IR Remote Control for the IR Speed Remote Control (8879) (http://brickset.com/sets/8879-1/IR-Speed-Remote-Control). The Speed Control remote allows for all the basic functions of the IR Remote, but also adds speed dials to the mix. Each speed dial can be increased or decreased in steps, allowing for smooth control of locomotives and other models. Each speed dial also has a red kill switch, which will immediately send a signal to the IR Receiver to set the power on that port to zero, effectively stopping the motor.
For the Matson’s Landing Climax, I’m using a very simple application of the last PF setup. The battery, IR Receiver, and a Medium Motor (8883) (http://brickset.com/sets/8883-1/M-Motor), will ride on the base of the locomotive. An small 8-tooth gear is attached to the output of the motor. This gear meshes with a second 8-tooth gear to transfer power to a larger 24 tooth gear that rides just below the base of the locomotive. The large gear drives the axles that are connected to the universal joints of each truck, thereby driving the locomotive’s wheels. The small to large ratio of the main drive system gears the power down, decreasing the overall speed of the locomotive, but increasing the power. While it doesn’t look as flashy as a speeding locomotive, it is more typical of a logging locomotive on a mountain line.
In the next installment, I’ll talk about track testing, and how the results will drive the design of the Matson’s Landing track plan.
Central Railroad of New Jersey 1940’s Commuter Train in LEGO
This is my LEGO model of a 1940’s Central Railroad of New Jersey commuter train. This train is typical of those that made up the CNJ’s short haul commuter service in the first half of the 20th century. You may have already seen the locomotive in my recent article on Vinyl Decals, or on a recent youtube livestream. Now that the locomotive is properly decaled, I finally took some time to photograph the whole train and write this article.
The seeds for building this train were planted several years ago while on a trip to visit Steamtown National Historic Site. While there one of the locomotives that caught my attention was an odd little Canadian National engine, no. 47. Canadian National no. 47 is what is referred to as a “Suburban” locomotive. These locomotives were built for short haul service on commuter lines. The Suburban type had its tender, carrying coal and water, integrated with the main frame of the locomotive, rather than having a separate “tender” car semi-permanently coupled to the locomotive. This gave the locomotive excellent dual directional capability, handy for when there were no provisions for turn the engine around at the end of it’s run. It was not uncommon to see these engines running backwards pulling their train on a return trip.
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.
