MOC: 1:22.5 Bulgarian 2-10-2T narrow gauge steam engine (class 600.76)
Sven J posted a topic in LEGO Train Tech
Dear AFOL trainheads, After almost six months of designing work, another five months of construction, countless bursts of temper, and being relieved of a small fortune, I am very proud to present my latest locomotive MOC. This time, it’s a 2-10-2T narrow gauge (760 mm) steam locomotive, class 600.76, of the Bulgarian State Railways (Balgarski darzhavni zheleznitsi, BDŽ). Basically an enlarged version of the German DRG Baureihe 99.73, the first five locomotives of the class were built in 1940 by BMAG (formerly L. Schwartzkopff) in Berlin for hauling all kinds of trains on the mountainous Rhodope railway from Septemvri to Dobrinishte. Delivering about 850 hp, the engines were extraordinarily powerful by the time’s standards for single-frame narrow gauge locomotives. They were so successful that the BDŽ were keen to acquire more, but after the Bulgarian Tsardom had turned into a communist republic at the end of WW II, it became almost impossible to buy industrial goods from German manufacturers. Thus another 10 engines were delivered in 1949 by Fablok in Chrzanów, Poland. These Polish-built locomotives were technically identical to the original Schwartzkopff ones, but could easily be distinguished from the first series by the combined steam/sand dome casing and the odd-looking smoke deflectors, which seem quite ridiculous on an engine with a top speed of no more than 45 km/h! From 1966 on, after new diesel locomotives had arrived at Septemvri, all class 600.76 locomotives were relocated to Cherven Bryag in northern Bulgaria. Several have survived until today, albeit most of them in desperate condition. One engine – No. 609.76, however, is in operational state (now stationed in Septemvri again) and regularly used for excursion trains. My model portrays a locomotive from the second series as it ran in the late 1960s, some years after the whole class had been equipped with compressed-air brake and supplementary oil firing. As opposed to the drawing, it therefore has a shortened right side tank (to make room for the air compressor), air reservoirs below the rear tank and an extended coal/oil bunker. The model is in accurate 1:22.5 scale except for the track gauge, which according to G-scale standard is always 45 mm regardless of the prototype’s actual value (as mentioned before, class 600.76 has 760 mm, or 33.8 mm in 1:22.5). Therefore, it matches LGB garden railway track and rolling stock. Dimensions and height of the coupling bars are designed in a way that they work with LGB link-and-pin couplers. Three PF L-motors working on the central driving axle are responsible for propulsion, with the other drivers (BBB XL) being coupled by the side rods, just as in the real thing. One BuWizz brick allows to remote-control running direction as well as speed, and serves as a power supply for the lights (separately switchable front/rear headlights, combined cab & running gear lights). The LED equipment was purchased from Brickstuff; valve gear parts and main rods were supplied by zephyr1934. The running gear layout proved to be quite a challenge. The leading and trailing axle are of the Bissell type and can swing out by 9°. Of the driving axles, the second and third one are blind, while the fourth one is slidable laterally by +/- ½ stud. With this configuration, the engine is running stably on straight track, yet also able to negotiate LGB R3 curves and switches (1195 mm radius). The model consists of more than 3200 parts and weighs about 2.2 kg. Enough said – enjoy the pictures! Some views of the engine frame. For reasons of stability, I had to fill the prototypic cutouts with trans-clear plates and bricks. You can see the steam inlet pipes running to the cylinders on the outside, as well as the exhaust pipes inside the frame, leading steam to the exhaust nozzle in the smokebox. Underneath, the brake rigging is also reproduced: The leading/trailing trucks. The tongue connecting the truck to the main frame is free from load, which means that it could be kept prototypically thin; the engine weight is supported by the axle bearings via the 4x4 tile on top. Fully detailed cab interior, including a tiltable ”Marcotty“ type firebox door and functional folding seats: Complete smokebox interior as well. The exhaust nozzle, spark arrestor, smoke stack bottom, boiler tube openings and superheater tubes are visible: Plenty of water in the side tanks: Some boiler details, among others showing the generator hidden behind the smoke deflectors: The combined oil/coal bunker can be removed to give access to the power button and the charging socket: The three magnetic switches for the lights are hidden in the rear toolbox: Posing in front of a historic BDŽ crest: The cab lettering: The lights: Some matching, albeit non-purist decoration (1:24 GAZ M20 Pobeda by Yatming, 1:22 [sic!] VAZ/Lada 2106 by Avtoprom)… A short video, showing the valve gear in motion. Note that unlike many conventional model locomotives, the valve stem is really pushed back and forth. A video of the engine pulling an LGB G-scale train will follow as soon as possible. As always, you can download the lxf file here. Also, more and much larger pictures can be found in my Bricksafe folder. Finally, I’d like to say special thanks to Sergio Monai, who with his fruitful feedback and proposals kept me stimulated to achieve the best possible result! Comments are of course most appreciated – thanks for stopping by! Best regards, Sven Edit: New video here! -
MOC: Just a humble 0-8-0T... (Flensburger Kreisbahn No. 1 in 1:22.5 scale)
Sven J posted a topic in LEGO Train Tech
Dear train lovers, It's time for another locomotive MOC! As a tribute to my favourite holiday region (where in fact I am right now, writing this), I chose the Flensburger Kreisbahn's No. 1, a 0-8-0T narrow gauge locomotive, as a prototype. The Flensburger Kreisbahn ("Flensburg county railway") was a 1000 mm gauge railway in Germany's extreme North, with two lines (94 km in total) running through the hills of Anglia close to the Danish border. When the railway's older, saturated-steam locomotives became too weak to handle increased train loads, two new superheated-steam engines were ordered from AEG in Berlin - yes, there was a time when AEG, famous for its electrical devices, also built steam locomotives! Delivered in 1926, these 0-8-0T engines, numbered 1 and 2, were an immediate success. With approx. 300 hp and a permitted speed of 40 km/h, they were suited for both freight and heavy passenger trains and remained in service until the railway's closure in 1953. Sadly, both locomotives were scrapped. A substantial problem while designing the model was the almost complete lack of reliable sources. All technical information had to be derived from a short description, some b/w photos and a single small drawing in just one book (Schöning/Kupfer: Die Flensburger Kreisbahnen. Verlag Kenning, Nordhorn, 2004; the drawing is reproduced below with kind permission by Mr Kenning). Nevertheless, I'm confident that my model comes as close as possible to the real engines. The MOC consists of approx. 2,200 parts and weighs just under 1.5 kg. It is held in accurate 1:22.5 scale, therefore compatible with conventional garden railway equipment (45 mm G-scale track), and can be coupled to rolling stock fitted out with LGB link-and-pin couplers. My layout uses the LGB R3 radius (1195 mm), so the locomotive has to be able to negotiate these curves. However, as I wanted to avoid the use of blind drivers for aesthetical reasons, this required two little tricks: The last axle is slidable sideways by +/- 1/2 stud, and the second axle's wheels are slightly set inwards, resulting in an increased lateral track play. Although this arrangement causes some drag while negotiating curves, it nevertheless works. The locomotive is driven by two L-motors. A BuWizz functions as both a battery pack and remote control receiver. The lighting equipment was bought from Brickstuff, while the wheels are BBB XL drivers, as usual. Purists may kindly ignore the two following scenes... Of course, the engine crew was proud to pose for a souvenir photo. Even the local grocer came to have a look at the new locomotive. The engine frame: While my previous BDZ 606.76 had its focus on exploring the possible level of detailing for a LEGO model, this time the goal was to design a simple locomotive for uncomplicated operation. Above all, the new model had to overcome the 606.76's proneness to tipping over. Thus, the frame houses two weight bricks for improved traction and a lower centre of gravity (highlighted in blue): Some views of the brake rigging and the two large vacuum-brake cylinders: All drivetrain components, including the BuWizz, are tightly packed and positioned as low and as close to the engine's centre as possible, again with the aim of optimizing the COG: The power button and the charging socket are accessible by removing part of the boiler top: The cylinders, closed-type feedwater heater (system "Knorr"), and generator: The upper part of the cab. While looking quite simple, the task to model the roof's half-stud offset and the vent hole in the cab front almost drove me nuts... But I think I found a satisfying solution: Cab interior and lights: This time there was no space for magnetic switches to control the headlights; so the coal bunker contains two small separate battery packs (with built-in switches) for front and rear lights. The cab is illuminated, too, when any of the two circuits is turned on. Realistic Winterthur valve gear. The basic dimensions are the same as on my BDZ 606.76: Originally, I had used zephyr1934's rods and valve gear parts again. But then I found them to be looking too massive , considering the rather delicate rods of the prototype. Besides, during the first functional testing sessions of the near-completed model, the flex elements which I originally used for the side rods proved too large by just a fraction of a millimetre - the cable connectors collided with the rear mounting of the crosshead guide, something which could not be foreseen in LDD. So I knuckled down to get used to Tinkercad and designed my own rods, including thinner, slightly tapezoidal main rods as well (both subsequently made by Shapeways). And for the first time - SMOKE (using a Seuthe No. 99 smoke generator, powered by the BuWizz via a modified PF cable): I finished the model just in time before going on holiday, so I had no time to shoot a video on track. Of course, I'll do this when I'm back home again. In the meantime, your feedback, comments and criticism are most welcome! As usual, high-resolution images can be found in my Bricksafe folder. If someone should be interested in the LDD file, please contact me by PM. Thanks for stopping by! Best regards, Sven Edit: Now with on-track video - see here! -
MOC: 1/22.5 scale Kitson-Meyer - Ferrocarril de Taltal. UPDATE: Now with video!
Sven J posted a topic in LEGO Train Tech
Dear trainheads, Finally, my new locomotive is ready! This time, I chose a prototype from quite a distant edge of the world - an articulated narrow-gauge (1067 mm) 0-6-6-0T "Kitson-Meyer" engine belonging to the Chilean "Ferrocarril de Taltal" (FCT; written as "Ferro Carril Taltal“ on locomotive number plates), or "Taltal Railway". Ten of these locomotives were delivered to the FCT by Kitson & Co. (Leeds, UK) between 1904 and 1907, and further eight engines later acquired second-hand. Over the years, several modifications were carried out: For example, all engines were converted to burn oil soon. Water and fuel capacity of some locomotives (including No. 50, the prototype for my model) were increased by adding welded enlargements on top of the side and rear tanks. "The Railway Magazine" gives a short description of the FCT (Vol. 90. No. 551, May-June, 1944, pp.158—159): More detailed information can be found in the books "The Taltal Railway" and "Kitson Meyer Articulated Locomotives", both by Donald Binns, which were my two principal sources. In general, very few technical information about the FCT locomotives can be traced. Despite searching for months, I wasn't able to find a detailed drawing. So I had to largely rely on taking measures from photos and on one single, distorted sketch on a data sheet describing the near-identical engines from the "Ferrocarril Tocopilla al Toco" - see below. (While there are numerous photos of the sole surviving FCT Kitson-Meyer, no. 59, nearly all of them were taken during the engine's last years in service, when it was already in a very poor state of maintenance, or since it has been on display as a monument. Because of that, it's difficult to conclude how it looked in better days. Nevertheless, I hope - and believe - that the model's overall impression comes close enough to the real locomotive's appearance.) The model is held in accurate 1/22.5 scale. It consists of quite exactly 3,000 parts and weighs in at 2.4 kg. The engine is powered by two L-motors (one mounted vertically in each bogie); each motor has its own BuWizz as a power supply and R/C unit (technically, one BuWizz would suffice, but this configuration allows for longer running times). The wheels come from BBB and the lighting equipment was purchased from Brickstuff, as usual, while the rods are 3D-printed parts of my own design. Enough said – enjoy the photos! Data sheet for the similar engines (though with different brake equipment and cab) of the "Ferrocarril Tocopilla al Toco": Detailed cab... ... and also smokebox interior, showing the exhaust nozzle, the base of the chimney and the boiler tubes: The cab roof is detachable. The ventilation flap really opens, you can see the lever for the steam whistle through the hole: The top of the Belpaire firebox is also detachable, giving access to the charging sockets and the power buttons: The lower part of the cab ladder is attached to the bogie and turns with it. Note also the chain which prevents the bogie from jackknifing in case of a derailment. Advanced lighting functions, controlled via two BuWizz channels: Before starting their daily trip into the Andes, engineer and fireman still have enough time to pose for a photo with their trusty old lady... ... while one of the brakemen uses the unexpected spare time in a different way. Well, but not for long. Soon "El Jefe" arrives in his flashy Chevrolet and critically watches his employees' activities... A few shots from the building phase, showing further details. First, the bogies with the motors. You can see the leaf springs underneath, as well as the brakes and (as on the real thing) only one single sanding pipe in front of the first wheel: The firebox once again: The main frame. The ashpan contains two weight bricks, which help to keep the centre of gravity low and thus to prevent the model from tipping over. And a view of the complete technical layout with batteries and motors. The multi-coloured bricks underneath are just the building stand. Full-resolution images can be found in my Bricksafe folder. At the moment, it’s too hot in my attic for filming, and I’ll go on holiday next week; but when I’m back, of course I'll shoot a video of the locomotive and its train, so stay tuned! Last but not least, I'd like to give my heartfelt thanks to all those AFOLs who attended the development of this model with their feedback and encouragement; and especially (though we've never met in person) to my dear "pen-friend" Sergio Monai @monai, whose multilingualism and commitment were an invaluable help during the research phase. Comments and criticism are of course most welcome! Thanks for stopping by! Best regards, Sven Edit: Video now available here! -
Dear fellow AFOLs, it’s been quite a long time since my last MOC, but finally, I am proud to present another one. And I dare say that the waiting was quite worth it… But let’s take one thing at a time: I’ve always loved Swedish steam locomotives for their clean, elegant lines, their beautiful colour scheme and those massive snowploughs ; so when the Mallet project I announced a few months ago had failed, I thought it was time for an old Scandinavian lady in 1/33 scale – the TGOJ M3a No. 104. The prototype is a three-cylinder 0-8-2 tank engine (did I mention that I love tank engines, too?). Four of these locomotives were built between 1928 and 1930 by Nydqvist & Holm AB (NOHAB) in Trollhättan, Sweden, and delivered to Frövi-Ludvika railway, where they were classified as Litt. M3a, nos. 101–104. From 1931 on, the engines were operated by TGOJ (Trafikaktiebolaget Grängesberg–Oxelösunds Järnvägar). They were used primarily in freight service, e.g. for hauling ore trains to the harbours on the Baltic Sea. While engines 102–104 were scrapped in 1975, no. 101 is preserved at the railway museum in Grängesberg. The model consists of ca. 2100 parts and weighs about 1.4 kg. It features a working reproduction of the inner cylinder and a realistic frame with prototypic cutouts, inside-mounted equalizing beams, and brakes. The cab interior is as detailed as possible, given that the battery box is placed inside the cab. Two L-motors, controlled via one IR receiver (V2), are working directly on the fourth axle; the first to third axles are driven by the side rods. All the rods were made to measure by zephyr1934 (and I really want to thank him for this great job!), while the wheels are BBB XL and Medium ones. Enough said, here are the pictures: The frame during construction, showing the prototypical inclination (approx. 6,7°) of the middle cylinder, which allows the connecting rod to clear the first axle: Two more views of the frame. You can see the equalizing beam between the first and second axle as well as the one between the third and fourth: The motors are situated in the side tanks and in the lower half of the boiler: A longitudinal section (render). The red boat weight brick improves weight distribution: Some cab side detail. Note the small windshield glass between the windows: Self-made stickers: The rear windows are barred, to prevent them from being damaged while taking coal: The roof is detachable for easy access to the on/off switch and the charging socket. You can also see the rudimentary cab interior: Finally, here’s a video, showing the locomotive in action. Despite its long wheelbase, the model is able to negotiate LGB R3 curves and switches, as the trailing axle (Bissell type) swings out both radially and laterally (Note: The brakes between third and fourth axle are for display only. In operation, they have to be removed; otherwise, they rub against the fourth axle’s flange and make a terrible noise). As usual, you will find larger versions of the pictures in my Bricksafe folder. You can also download the LXF there. Thanks for your kind interest! Best wishes, Sven Edit: New videos here!

MOC: 1:33 Hohenzollern 0-6-0T v2.0 - UPDATE with new features
Sven J posted a topic in LEGO Train Tech
EDIT: Model's latest revision HERE! Dear train community, a while ago, I presented my model of a small industrial shunting engine (for information about the prototype, and to compare the pictures below with version 1.0, please see here). However, although it proved to be a strong and reliable little locomotive, I was never entirely happy with it: The roof turned out to be very flimsy, and the battery box and IR receiver were completely blocking the view through the cab. So when BuWizz was announced, and I realized that its height would be considerably lower than that of 84599, and it would need no additional receiver, I thought I should give it a try and rebuild my MOC (even though this meant that I had to get a smartphone… ). The revised model has been completed for a couple of weeks now, but it wasn’t until last week that a BuWizz app version was released which allowed to control two output channels via one slider, so I couldn’t let the engine run until then… (By the way: One more thing that I would really wish for would be an option to „lock“ the slider in a given position, so that you don’t have to keep your finger on the phone all the time when the engine is running. Maybe someone from BuWizz will read this… ) Following alterations have been implemented: - BuWizz replacing the rechargeable battery box - boiler diameter increased by one plate for better scale accuracy and a brawnier appearance - slightly larger, smoother side tanks - revised colour scheme without black striping (thus adding to the stouter look) - additional small windows in the cab front - completely redesigned cab roof with more prototypical profile and no longer needing transparent plates to support the door openings - handrails below the buffer beams for the shunting men - strings as sand pipes - improved shape of the cylinders - smaller headlights - (at least rudimentary) cab interior thanks to the reduced height of BuWizz But unfortunately, still no opening doors – sorry, Sergio! (I promise my next model will have them. And it will be a BIG model. REALLY big!) With BuWizz set to „slow“ mode, gentle and precise shunting becomes possible; something one couldn’t even dream about while using Lego’s IR remote control system. As always, you will find larger versions of the images in my Bricksafe folder. Comments are of course most welcome. Thanks for stopping by! Best regards, Sven EDIT: Model's latest revision HERE! -
Found this Polish Pm36-1 on Youtube, think its worth looking at!
JEB314 (James) posted a topic in LEGO Train Tech
Just found this new video of a Polish Pm36-1 steam locomotive by Fasolic ( @solic ). I've not seen any coverage given to it, and it is a marvellous model, very much got LNER A4 vibes! Love the Dark Blue colour and the integration of full PF in the loco! Anyone know its history? -
MOC: 1/33 wooden passenger wagon (Scandinavian style) with full interior
Sven J posted a topic in LEGO Train Tech
Hello AFOLs, as promised, here’s the passenger coach for my Swedish museum train (if you don’t remember, here are links to the locomotive and the freight wagon). There is no specific prototype for this MOC; instead, I tried to reproduce the characteristic features of several types of wooden pre-WWII Scandinavian coaches. The wagon is lettered as no. 3 of JMJ, a fictional museum railway, which (by mere chance, of course ) uses the same abbrevation as the last Swedish line that operated steam locomotives in regular service. As with my previous wagon models, the roof is detachable, so you can see the fully detailed interior: Tasteful two-tone wall panelling, and a toilet paper roll in the lavatory compartment (see below). The curtains were inspired by those on marbleman’s Orient Express coaches. A shot of the interior during construction: The lavatory compartment, of course equipped with a toilet brush… … as well as a washbasin, a towel roll and a mirror. Some bogie detail, showing the primary (coil springs) and secondary (leaf spring) suspension and the axle-driven generator for the car’s electrical supply: With just over 2100 pieces and a length of 62 studs plus buffers, this is my largest MOC so far. One bench alone consists of 30 parts: I also designed a first-class version of this coach, with only six windows per side and more generous seat spacing; however, due to the lack of time and space, I chose to build only the second-class car (for now, that is). A video of my TGOJ M3a pulling the museum train will follow as soon as there’s sufficient sunlight to shoot it – at the moment, it’s all dark grey here (some of the photos were taken with exposure times > 1 sec)... As always, you will find additional images and larger versions of the photos in my Bricksafe folder. Thanks for stopping by! Best regards, Sven Edit: Videos now available here! -
Hi everyone, of course, my Swedish tank engine needs some adequate rolling stock, so I designed two different types of cars in 1/33 scale: a four-axle passenger coach, which should be finished in ca. 10-14 days; and the open, two-axle freight car presented here. The model is lettered as no. 1 of a fictional museum railway, which uses the wagon for bicycle transport: As usual, larger pictures and the lxf are available on Bricksafe. When I have completed the passenger car, I will make a video of the whole museum train, too. Hope you like it! Best regards, Sven Edit: Videos now available here!
