It's all about manufacturing cost. The amount of labor in nose of the E/F units was too much to absorb. They were made from many small pieces welded together, then ground to a rough shape and finished with plastic filler and sanding. The purchasers of the locomotives could demand those shapes if they are willing to pay but none are, regardless of what railfans desire.

Nicely done on all. I especially like your equalizer side frames! Dave

Great news, looking forward to getting them!

Very nice, I love it. Any thoughts of selling plans?

I agree with the others, this is a really beautiful engine and train. What kind of LED's are you using for your lighting? Dave

Thank you both. When I was a kid, I wished for but never got a Lionel steam engine with smoke, hence my obsession to make it work here. Dave

I posted about my SP Daylight Locomotive with a Seuthe smoke generator in this thread a few weeks ago: I haven't been happy with the Seuthe unit though as it leaves a little oily residue behind and doesn't run very long. After seeing this thread: I've been experimenting with a similar ultrasonic mist generator using just water as the working fluid. I purchased it on Amazon, which uses a 16mm disc: href="https://www.amazon.com/gp/product/B073322QF8/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&amp;psc=1" rel="noreferrer nofollow">www.amazon.com/gp/product/B073322QF8/ref=ppx_yo_dt_b_asin...</a> It's powered by the locomotive batteries with the control board mounted in the tender. Using a 3D printer to make the reservoir and stack, I finally got a reliable working device, which has a 4x5 stud footprint: Here's some of the iterations it took to get it working: Here is the final design in action: The unit fits in a cavity I created in the front of the locomotive ahead of the drive for the air pump: Here's the finished application. Note I did have to modify a tile and some headlight bricks to make it fit: A cover lifts off to access the water reservoir. It holds about 9ml of water, enough for more than 8 minutes of operation. This is a stationary test of the system: Finally, in operation: Just like a real steam locomotive, it leaves water behind wherever it runs! Dave

Really like it, including the dark blue! Better buy that Dish 5x5 Scala in LBG before the price gets more insane. https://www.bricklink.com/v2/catalog/catalogitem.page?P=6942&amp;name=Dish 5 x 5 Scala&amp;category=[Dish]#T=S&amp;C=86&amp;O={"color":"86","iconly":0}

Sure, here's the batteries from Amazon: https://www.amazon.com/gp/product/B072MDXZ3K/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&amp;psc=1 I like to use ones that have a built-in current limiting circuit, just in case of an accidental short. The battery holder was hard to find but I ended up going to Digi-Key for a dual holder from Keystone Electronics, https://www.digikey.com/en/products/detail/keystone-electronics/1102/5255486?s=N4IgTCBcDaIMwDYC0BGFAGMSB2ATEAugL5A. They also have a single holder part no. 36-1101-ND. I bought a 4 position charger that handles both 18350 and 18650 batteries from Amazon that they no longer carry. Here's details on the rest of the electronic parts: The diesel loco genie came from here: http://xlsystemsdcc.com/product/xl-wireless-diesel-sound-module/ The speaker it comes with is even smaller than that pictured, I using the one pictured which he also sells. It's pretty easy to fit in an 8 wide model. Any switch will do but I like these latching pushbutton ones: https://www.amazon.com/gp/product/B07DWS195R/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&amp;psc=1 I'm using these LED's: https://www.amazon.com/gp/product/B07FN6VBN9/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&amp;psc=1 which I glue to the inside of clear 1x1 round tile. The wires are so thin they will just fit between mated bricks with hardly a bump. Two batteries only produce 7.4V but it seems plenty for the Loco Genie. Dave

Such a unique locomotive. Thanks for the background info. You've made a beautiful MOC.

Thanks zephyr. I'm somewhat embarrassed to show the whole layout as I've let my 5 & 7 year old grandsons freely play with the minifigs and buildings while I run the trains so it's quite a mess; someday I hope they take over the trains. I'm old school, having grown up with Lionel 027 then HO. I've built about 270 sq ft of tables (25 sq m) but will never ballast the track so I'll never be in the same company as some of the fantastic layouts I see here, on youtube, and at shows. I'm really focused on the rolling stock, at least at this point.

Beautifully done. What was the fuel? I love your hook and buffer!

Thanks. Yes it is, a great addition to my layout!

Thanks for the positive comments. I should also have mentioned that Andrew at OKBrickworks provided the custom stickers to match the prototype.

I was inspired by jtlan's MP15DC here: to create my 1:48 scale MOC of the EMD MP15AC, an upgrade of the MP15DC that included a traction alternator rather than a DC generator and a cooling system including an AC motor fan as opposed to the belt-driven fan of the DC model. Southern Pacific bought 58 of these, all delivered in 1975 - here's a builder's photo: I borrowed parts of the cab from jtlan's model and trucks were inspired by the GP swing hanger trucks on the GP60M plans I purchased from Brick Train Depot. The model has two Lego train motors and is controlled by an MRC Loco Genie wireless DCC system. I made some upgrades to the model that represent mods the RR did or could have done to modernize the unit; ditch lights that were added, and an exhaust spark arrestor-silencer system (the raised hatch over the engine) that all units built after 1980 included to meet noise regulations that went into effect then (designed that system during my career at EMD so had to include it). In the interest of full disclosure, I did make modifications on a few parts and I dyed a few parts that weren't available in DBG. The hatch cover for the engine air filters lifts off to access the pushbutton switch to turn on the power: I used two 18350 3.7V Li-ion rechargeable batteries which easily fit under the removeable engine hood: I normally use 3 18650 batteries on my Lego locomotives with the Loco Genie but I'm finding these two smaller batteries work well. Here's short video of the locomotive operating: Dave

I agree they look and fit well but I am having trouble with the couplers uncoupling due to height variation when climbing the grades on my layout. I find they statically match in height perfectly but when tractive effort is applied, one may tend to "droop" about one half the knuckle height; then climbing the hill, the trailing coupler drops below the pulling coupler at the transition back to flat. I know my transitions are not the smoothest so it's mostly my problem but I'm now trying the Studly Trains new magnets and find they are working great. So I'll probably sell the BMR Kadee's. Dave

Yes, it is the heavy steam sounds version. I didn't do anything to synchronize the chuff, it just worked. It's rated at 1.5 amps, I did do a test on the Daylight, which has two train motors plus the L motor in the locomotive to see how long the batteries would last. I would have been okay if I stayed on the flat layout loop, but at 20 minutes, the genie went up in smoke on the near the top of the grade on my outer loop. Total current on the flat was only about 1 amp but climbing the grade it went to near 1.5 amps so the rating might be a bit optimistic, especially buried in the loco with no air circulation. I also have four diesels with the diesel loco genie, I think it's the best solution to get the features of track based DCC without having to use track power, and the price is cheaper than a PUP hub. They seem to be discontinued by MRC, but XL Systems, who apparently designed it for MRC, has a web store and sells them direct. I just ordered 3 more diesel units and have a few steam in inventory for future projects. They show up on ebay often too. I've been moving from 6 wide to 8 wide and will eventually sell all my PUP units. I'll sometime have to post my MP15AC MOC using the loco genie powered by just 2 18350 Li-ion cells, which seems to work just fine powering two train motors. Dave

Is it included in all the sets of the QJ or just some more recent ones? Is there a set part number to be sure it's included?

Thanks everyone for the comments. I grew up with Lionel and then HO train layouts so that's my mindset. My wife likes to build the modular buildings so they're all hers. The layout is a mess as our 7 and 5 year old grandsons like to play with the minifigs and vehicles while I run the trains. Someday I need to start on scenery although I have no intention of ballasting track. I have a 6990 Futuron monorail set I plan to remake as a tram serving the amusement park next.

Rather than hi-jack this thread, I started a new one on my loco that does just that.

Warning - Purists look away, some drilling and modifying of Lego parts was required. Rather than hi-jack the Mould King thread which now discusses smoke generators: I thought I would show my locomotive with a smoke generator. I started by purchasing Tony Sava's plans for the Southern Pacific Daylight 4-84 locomotive and coaches and heavily modified it. I had a lot of trouble negotiating the grades on my layout, which have not particularly smooth transitions, using just train motors in the tender so I motorized the locomotive with a PF L motor. I don't recall my inspiration to add pulsed smoke, I saw it somewhere though, so I added a 8-14V Seuthe smoke generator and a Lego air pump driven off the drive motor. Some milling and drilling was required to mount the smoke generator and the air tubing. I tied the spring on the air pump so it doesn't add much resistance. The whole thing is controlled with an MRC Loco Genie that is a wireless DCC system and powered it with 3 18650 LI-ion batteries nominally providing 11.1V. The Loco Genie has sound and directional and effects lighting and is powering the two PF train motors in the tender and the L motor in the loco. The batteries, an amplifier and 40mm speaker and the Loco Genie are all in the tender.You can see it in operation here; Note the coaches have a provision that allows the diaphragms to touch on straight track but separate for curves. The curves on the outer loop in the video are R56 and greater; the grade is 4%. To deal with the grade and rough transitions, there is a sprung suspension allowing the trailing bogie on the loco +1/-2 plates vertical travel. while the pilot bogie is weighted with titanium putty to keep it on the rails. This video has a not so great narration but during the last minute shows the internals for the tender: Finally, here is a video of the internals of the locomotive showing the air pump in action: Now I'm really intrigued by the use of an ultrasonic mister and might try that out while keeping the air pump. Dave

This looks like the guts of the smoke device: https://www.amazon.com/WHDTS-Ultrasonic-Atomization-Atomizer-Humidifier/dp/B073322QF8/ref=pd_bxgy_2/132-6394248-6252861?_encoding=UTF8&amp;pd_rd_i=B073322QF8&amp;pd_rd_r=ac72cd41-184f-4627-a62c-4916fede9844&amp;pd_rd_w=eO5qd&amp;pd_rd_wg=7CRSb&amp;pf_rd_p=f325d01c-4658-4593-be83-3e12ca663f0e&amp;pf_rd_r=D9E8HTBFQWFKN4S0WRJ6&amp;refRID=D9E8HTBFQWFKN4S0WRJ6&amp;th=1 Just have to figure out how to do a small reservoir.

Thanks for that link, I wasn't aware of that part. For some 3 axle coach bogies, I machined the flanges off on some metal axle wheels (I have a lathe) but in my case with 8 wide pedestal primary suspension bogies, as Zephyr notes, the middle wheels are mostly invisible so its easiest to just run without them. For a 6 axle locomotive, it insures all the weight is on the driven axles so maybe that's the best solution.

Dennis, your bogie looks good. What part are you using for the unflanged wheels at the middle axle?

Very nice detailing, love the EMD engine, really great what you can do at 10 wide. In the last two pictures, the wheels appear to be no. 4185 Technic Wedge Belt Wheel (Pulley), is that what you're using? Dave
