Criga88 Posted October 17, 2015 Posted October 17, 2015 Hi all, after a few sightings of the 81 class while out and about in Sydney last month I decided to try my hand at a train MOC. This locomotive was a natural starting point for me with its boxy design and duplicated cabs at each end so integrating PF was easy. I'm also fond of the blue and yellow scheme of Pacific National even if they are more of a darker colour now with the weathering and exhaust stains over the years. The locomotive is set up for an IR receiver hidden between the exhausts and a single battery box and M-motor in the front half (LHS of pic). This should provide sufficient pulling power for a moderate consist however if I move the IR receiver to one of the cabs there's enough space for a second battery and motor. Quick question for the more experienced train builders though, is it possible to control two separate batteries and motors with a single IR receiver? I've ordered the parts to replace all of the light bley temporary pieces and to build powered bogies which should be arriving soon so I'll get some track set up to test this bad boy, I'll post a video of that once it's done. Comments, criticism and questions are welcome, and keep an eye out for more. Quote
zephyr1934 Posted October 18, 2015 Posted October 18, 2015 Lots of great detail in your MOC, you packed a lot especially in to the ends. Excellent work and looking forward to seeing more. Quote
LEGO Train 12 Volts Posted October 18, 2015 Posted October 18, 2015 Nice Moc and beautiful nose details! For your question you can use one IR receiver powered with one battery pack (but you can use AA batteries to have energy for more time) and two motors Quote
Criga88 Posted October 18, 2015 Author Posted October 18, 2015 Thanks everyone, I try and pride myself on the details in my MOCs. I suspected that the IR receivers would be limited to a single battery, looks like I'll have to settle for more locomotives when this reaches it's maximum pulling power then Quote
THERIZE Posted October 18, 2015 Posted October 18, 2015 Nice! I'm curious about how you will make the bogies though. Quote
michaelozzie Posted October 18, 2015 Posted October 18, 2015 Very nice to see a MOC of one of these locomotives and a commonly seen livery in NSW. I've been thinking about making an 80 class for a while in the candy livery. That's and engine I always remember well watching pass my grandads house when I was a child. Quote
Criga88 Posted October 18, 2015 Author Posted October 18, 2015 Thanks THERIZE and Michaelozzie. I say give the 80 class a try, it should be pretty easy to source the parts in red for the body with a just a line of yellow and orange plates for the stripes down low. As for the bogies I'm going to mod a pretty standard design for this, I'm trying to keep that area relatively simple to avoid any headaches, I'm aware that the rear axles bevel gear is on the wrong side in the render too Quote

zephyr1934 Posted October 22, 2015 Posted October 22, 2015 Thanks everyone, I try and pride myself on the details in my MOCs. I suspected that the IR receivers would be limited to a single battery, looks like I'll have to settle for more locomotives when this reaches it's maximum pulling power then If you put a pair of XL's in there and make sure the engine is heavy enough not to spin the wheels then the magnets will give long before you run out of pulling power. Make the couplings stronger and you will pull the cars off the tracks before you run out of pulling power. I've not played with any L motors yet but I suspect they would have a lot of umph too. Quote
Criga88 Posted October 22, 2015 Author Posted October 22, 2015 Thanks for the pointers Zephyr, I'll see how the M-motor handles the locomotive before I upgrade. I only have limited rolling stock as well but was planning on using some form of technic connection from the start. Parts should be arriving very soon so I'll be able to do test runs then. Quote
Chromeknight Posted October 23, 2015 Posted October 23, 2015 I see these growl past regularly. Very recognisable. All that's missing is the big white loco number on the side! My suggestion is don't worry about adding more motors until you have too many carriages to pull well because of weight or drag through curves. Quote
Criga88 Posted October 23, 2015 Author Posted October 23, 2015 I see these growl past regularly. Very recognisable. All that's missing is the big white loco number on the side! I've noted the locomotive numbers that I have seen lately so I have plenty to chose from for when I finish this and add decals, it'll be getting the Pacific National branding on each side and the front/rear numbers too.

Criga88 Posted November 13, 2015 Author Posted November 13, 2015 I received all of the bricklink orders this week and the locomotive is now running, the only bits left to complete are the interior details of the cabs, locomotive numbers and some greebling on the outside of the powered bogie. I'll make a temporary layout over the weekend to test the pulling power of this with my available TTX, Maersk and Santa Fe carriages. In the mean time here's the locomotive doing a test run around a simple layout: Comments, criticism and questions are welcome, and keep an eye out for more. Quote
Beck Posted November 14, 2015 Posted November 14, 2015 I really like this one! Runs nice and smooth. Make sure you put some weight over the bogie like a 2x8 54g weight. Quote
Criga88 Posted November 15, 2015 Author Posted November 15, 2015 Thanks Marook and Beck. Make sure you put some weight over the bogie like a 2x8 54g weight. I only have the one weight and I'm pretty sure it's at the very bottom of an unsorted 60L tub Quote
