6-10-10-6 Class 8MT Steam Locomotive "Big Blair" . Here is my early Christmas present for everyone. I present to you: my ultimate steam locomotive, #300486 "Big Blair"! . "Big Blair" has finally arrived! She is my 6-10-10-6 articulated compound steam engine, and the pride locomotive of my railroad. Technical Specifications: Length: 11 Straight Track Pieces Height: Unknown Amount of Standard Bricks Width: 10-Wide Power System: 8 Power Functions Train Motors Class: 8MT (Mixed Traffic) Here she is in all of her majestic splendor without the Christmas decorations. Quite the sight to behold. Big Blair as seen from the side. She is quite the monster and is fitting of her name. The front view of Blair. Some might say that she is simply an "up-scaled" Union Pacific Big Boy, but that is not the case. Unlike my previous locomotives which have had multiple influences, Blair is different. I wanted her to be the largest, yet still feasible, steam locomotive. Since the United States built the largest steam locomotive in the world, it only made sense to keep Blair as a primarily American design. The intent is make her look big, mean, rugged, ugly, and yet somehow beautiful to behold and truly worthy of being a "Mixed Traffic" locomotive. The rear view of Blair. The two rear lights on the back of the tender are able to accept a set of Power Functions Lights. Here is the wheel base that I used for Blair. I took away the rest of the locomotive so that the basic wheel structure could be shown. Due to the size of Blair, all of her drive wheel sets are able to articulate. It is not shown here, but there are openings at the front and back of each drive wheel set to allow Extension Wires to be run from the front motor to the tender. I went with a different design this time since I had the room. Instead of routing the wires through the boiler, I chose to route them through the drive wheels since the interior is hollow and spacious enough. The leading truck uses, once again, the 3 Axle Trucks design by Mike Kollross. As shown by my extensive use of this design in my previous MOCs, I really love this design because it is so ingenious! Thank you, Mike! Here you can see how the leading truck is connected to the front drive wheel set. A side view of a drive wheel set. Most of the details are carried over from my 4-8-8-4 Version 3 locomotive. After studying many pictures, I updated my drivers to the "more advanced" design. I personally like it a lot more than what I was previously was using. Another closeup of the drive wheel set. The trailing truck has the same basis as the leading truck. The trailing truck connects to the back of the second drive wheel set with a much shorter connector. I spent a lot of time with the leading truck to make it look just right with the ladders and lights. These lights are also able to accept the Power Function Lights. The front end of the boiler. Once again, I wanted that rugged and ugly look, which I believe that I achieved. The number boards will read "300486" when Blair is built in real bricks. An underside look that shows more detail of the leading truck that supports the cab and the firebox. A back view of just the locomotive, which also reveals part of the cab interior. Notice the space in the trailing truck, which allows the wires from the front to be routed through. The tender contains six of the eight motors used to power Big Blair. Also shown is where the IR Receiver is mounted. As with my previous tenders, the top is able to come off in two sections, the front and the back. The basic wheel structure for the tender. Only the middle two motors are attached to the tender. This design should allow for the tender to easily make curves. I took away one side of the tender to reveal the two layers that are hidden within. The bottom layer is used to route the motor wires and the extension wires, whereas the top layer houses the IR Receiver, the Battery Box, and any necessary Control Switches to ensure that the motors operate in the same direction. A look at the front end of the tender shows the opening that accepts the wires from the locomotive into the tender itself. Gracious space was given to allow flexibility when navigating curves and switches. This picture shows the scale of Big Blair, just in case no one has caught on to her massive size yet. The attached car is built to scale of the Emerald Night and is a 6-wide creation. Here is the customary front shot group picture of all of the steam locomotives that I have made so far. From left to right: Briana, Version 3, Big Blair, Version 2, and Version 1. Another group picture. Big Blair dwarfs all of the rest. So, here she finally is! I know that I have been inactive (sort of) recently, and this is why. I wanted to make sure that she was perfect for her debut. Many thanks go out to: jd davis: I have enjoyed talking with you about our creations and what we can do to improve them. By looking at your creations I have been able to overcome many obstacles with steam locomotive design in LDD (getting the driving wheels and drivers to match up perfectly is a pain!) The tender for your Mammoth is still a WIP, but it is coming along nicely. It will be up soon. Anthony Sava: I look to your creations a lot to find those small details that need to be added. Your Allegheny was a HUGE (see what I did there?) inspiration that made me want to create a large steam locomotive of my own. Go big or go home, right? Trevor Young: Once again, the advice that you gave me early on helped tremendously in ways that you could not imagine. One small piece of knowledge that is passed on can go a long way. Yay, I made it on the front page! This is my first creation to do so, which is quite exciting for me.
