Mammoth Boy Tenders . The tenders for the Mammoth Boy have finally arrived! . At long last, the project is finished. Fresh off of the production line from Nacho Enterprises Railway System (NERS) are the long awaited tenders (and also power units) for the Mammoth Boy by jd davis. This design underwent a few design changes, hence the delay. Here is the final product, worthy of such a monstrous locomotive. Here is the first of the two tenders, which holds coal in the upper section and water below. This is standard amongst the newer "box" tender designs. A top view of the tender, showing the massive holding area for the coal. Also shown is the IR Receiver. The middle section comes out, allowing access to the Receiver and Battery Box compartment. The entire top section has been removed to show the bottom section, which also holds the two XL Motors. A close-up of the XL Motors. The Technic pins are there so the motors do not fall out when the tender is picked up. The side of the tender has been removed to show the "cage" that I referred to in an earlier creation to hold the motors in place. The motors are able to pivot about in this "cage" whenever the tender enters and exits a turn. Part of the "cage" has been removed, showing more details. A close-up of the front of the tender. Since the first tender is built in 9-wide and the trailing truck of the Mammoth Boy has its aft coupler lower than standard height, I was left scratching my head for a while trying to design something that would work. Well, it does now. The lead coupler of the first tender is separate from the truck, and is simply connected to a 2x2 plate with an inverted pin. Why are the simplest solutions so hard to come up with? The rear end of the first tender. The coupler is part of the last truck, and as such sits at a standard height. The second tender, which is simply a canteen (that means it holds only water) built in Vanderbilt style. It is based on my earlier Vanderbilt tender design. Once again, the canteen is built in an odd number wide (number unknown at the moment), so some modifications had to be made. The top of the canteen. The IR Receiver sits underneath the hole on the top. The top of the canteen removed. The top comes off as a single piece, which is odd for me since most of my designs have the removable top in several sections. However, the canteen design prompted for this. Once again, the top section has been removed to show where the motors sit. There is also room in there somewhere for a Battery Box. So, the tenders each have two XL Motors, an IR Receiver, and a Battery Box. Which means that you will have to set each Receiver to the same channel. It also means that four motors will be a lot of hauling power. I saw a video of a locomotive that only had two motors in this configuration and it was easily pulling a lot of cars. How many, I cannot tell you. I lost count after twenty. The front of the canteen. It definitely looks more cylindrical than my previous version, which is partly due to it being one stud wider. That makes the tender an 11-wide. That answers the previous question. The rear end of the canteen, which sports lights that can fit Power Function Lights, and a combined ladder technique. The Mammoth Boy, with her (or is it "his"? Clarification please) new tenders. What a grand sight to see. A side view of the now completed locomotive. Even though each tender is six tracks in length, the Mammoth Boy still dwarfs both of them. That is insane, I tell you. A rear angled shot of the Mammoth Boy. This is probably my favorite picture. Hold the jokes. And your final parting shot of the majestic monstrosity that is the Mammoth Boy. *Twitch's Remarks* So, it is finally done. Back in December (I think?) jd davis asked me to power his Mammoth Boy, only because I asked how it was going to be motorized. He asked how I would do it, and thus I offered to create a solution. Through numerous delays (this thing called "work", being deployed, other projects, and making time for my wife) I was able to finish this. I am quite proud of how this turned out. Also, it SHOULD answer any questions on how my XL Motor Bogie/Truck design works and how it mounts. It practically just sits inside, not connected to anything (except the IR Receiver, but that does not really count). If this does not clear that up, I have no clue what will. The basis of this design should work for anyone has a freight locomotive that needs massive hauling power. Keep in mind that with how the motor/bogies/trucks are made, your locomotive will not be a speed demon. It deals with gearing and science that I do not feel like explaining, but it is set at a 1:1 ratio. Let us keep it at that. On a closing note, I have no NEW train projects at the moment. I will probably upload some others that have been put off or have already been featured (like the rest of the Christmas Train cars). However, I think that I will get back to building Mechas. I have had several ideas there for quite some time, but my train craze has kind of taken over recently. If anyone has any train-related requests that they would like to see from me or would like me to design, just let me know and I will see what I am able to come up with. Enjoy!
