    Octrainber 2021 and lots of coke

    Heavy industrial stuff on rails :-) Does the waggon carry melted ABS for new LEGO bricks?
  2. The work on my Vollert Robot DER 100 Critter continued. After solving the mechanical and motorized functions I concentrated on the design of the body and the wheels' cover. Therefore I started to build a second copy using brick-build dummy motors instead of the Curcuit Cube motors. The biggest challenge were the corner of the body between the hinged front/back and the side walls. But the little gap of the windows on the sides allow a droid arm to hold a dark grey double cheese slope at the top of the corner. Internally the droid arms are put in position using the "bar with 1x1 round plate (32828)" elements which are highly recommended for builds off the grid. Getting thinner and thinner the way down I decided to use just a 4L bar and a 3/4 Technic pin on the top. Not ideal but the best compromise I could realise at this point. I had the same thoughts like @zephyr1934 on the ladder steps on the sides. First I wanted to use the grille tiles but they stepped out to much. The flush solution came using 2x2 modified plate/tiles with 2 studs (33909). That means I will lose the "grille" effect. But never mind, the real one shows a very clean and flush design covering the wheels. I also played around with bars for the handrails on the side doors but ended up using inverted brackets to get a thin dark grey stripe on the all yellow side of the Robot. The 6 studs height of the door fits nicely in the 5 brick rows height on the side. I only had to replace a part of the dark grey "baseplate" with some tiles. But stability is still fine. Next: Squeeze in the Curcuit Cube and make it accessible to turn it on and off easily. And stickers? Stay tuned …

    PBKA Thalys WIP

    Great that you like my book :-) Back in 2010 or earlier Kai built his Thalys LEGO dark red was a new, rare color. No way to build such a MOC. These days it should be possible, even of dark red is more expensive then classic red.

    PBKA Thalys WIP

    Dark red looks really good for the Thalys! 11 (!) years ago a friend and I realized a huge train layout at LEGO Fanwelt in Cologne. The old video shows Kai‘s Thalys and my ICE 3
  6. Work on my "Critter" continued today with testing the functions. Both Curcuitcube motors are placed inbetween a chassis build by 2x 1x10 Technic bricks. One axle is driven, but I hat to cut a 2L axle a bit to make it a 1.5L axle so it fits well in the motor. The second motor drives the linear actuator which moves the magnet in and out. Yes, this idea is not my own development, @Selander did a great job on this technique already. Even with one buffer as counterpart the wip test shows that this concept works well. I need to add more guidance for the actuator when it moves out and in. The pulling power of the Curcuitcube is phantastic, one diven axle and moreless no balast on the Critter is enough to pull an old heavy 8-wide freight waggon. For a better clearance between the drive motor and the rails I replaced the original O-rings with larger ones from the sanitary department of the local DIY store. The have an outer diameter of 17.8 mm. The picture below shows the difference: Beside the extra clearance those O-rings also have more grip and I've been using them successfully on my BR 10 and other trains. Stay tuned ... And a big THANK YOU to @Ts__, @Asper, @Feuer Zug, @Tenderlok, @Paperinik77pk, @XG BC, @Hod Carrier, @zephyr1934 and all the others taking part in this years OcTRAINber challenge. Great to see all your Critters coming to live following your wip stories.
  7. My contribution for this years Octrainber "Critters" is Vollert Robot DER 100 "Leonhard Weiss", a tiny little modern shunter engine I saw the other day in real live traveling from Stuttgart to Nürnberg in Germany. A quick google search brought me to www.eisenbahndienstfahrzeuge.de with some pictures and additional information about this a bit strange looking "thing" on rails. The shape looks a bit odd but it might be a challenge for a LEGO model, especially the dark grey triangle next to the front windows. But yes, not another KÖF, but something modern. And Circuitcubes Bluetooth controlled mini motors are waiting here to be used in a train MOC. The prototype was build by the German company Vollert. Vollert does offer a few shunting robots from very tiny to mid sized locomotives. The Robot DER 100 has a total length of 5,45 m and a total weight of approx. 44 tons. It has a pulling capacity of 2,400 tons. This robot is powered either electric (cable or battery) or diesel-electric. As option it can operate in explosive atmosphere environments, e.g. chemical plants. The version I saw is operated by the German construction and building company Leonhard Weiss which is well known in railway construction. The LEGO MOC also will be powered by battery electric but I will not pull 2,400 tons of rolling stock ;-) But it will (hopefully) offer enough space for at least 2 Curcuitcube mini motors to power the drive and as special function a decoupling unit. If this works, I will get a remote controlle shunter with a high play value. Attaching a small linear actuator directly to the motor seems to work. Now I need to squeeze in everything in the dark grey/yellow body of the Vollert Robot shunter. A few years ago I already integrated a decoupling unit powered with PF in a 12 Volt MOC engine. So I already have some knowledge to integrate LEGO set 7862 in a locomotive. Stay tuned for the further development of my LEGO version of the Vollert Robot DER 100 ...
  8. ... my full loop of R88 curves (four packs of FxTrack 8888) also arrived today. Thanks to @michaelgale and European distributor JB Spielwaren. From the first quick look the R88s come in the same high quality as the R72s and S32s I already got. Looking forward for more great FxTrack stuff!

    [MOC] DB Class V60 Diesel shunter

    Great little engine @Asper ... I just saw the real thing the other day at the station here in Bamberg. Highly recognisable. The V60 also seems to the prototype for the old LEGO set #7760 Great to see how LEGO train designs have developped over the years and fans like you and me and many others create LEGO MOCs even closer to the real thing.
  10. Great MOC and very close to the real train. I also like the roof using the door-rail plates. Never seen such a design before.

    40516 Everyone Is Awesome

    Every Spaceman is Awesome I love the idea and the set #40516 ... and couldn't wait to build a Spaceman version ;-))
  12. The geared down motors should not be the problem, when lifting up the loco everything runs fine at a reasonable speed. I guess, the motors have not enough torque an the way from the middle section to both driven axles is to long and complex. The connecting rods also add resistance, maybe because the first "M" wheel is not using a 6L axle going through but rare black Technic pins without friction. I had to do this because the coupling of the small wheel is centered at the first "M" wheel. I am thinking of some nice cars for this locomotive so one can get another train motor as shown in the video where another engine is pushing.
  13. ... it has been a while, but now I can give you some update on my ongoing LEGO 12 Volt MOC project: LEGO 12 V Crocodile MOC After the hype around the LEGO 18+ Crocodile 10277 I thought of a 12 Volt compatible version, in 6-wide only, but showing all the iconic charateristics of a Crocodile engine. Of course, I looked carefully at the old prototype of a LEGO 12 V crocodile which shows a pretty long version using two 12 V train motors: As only non LEGO element I've choosen BigBenBricks wheels in size "M" (same size as it was used on the #7750) from @benfleskes. My 12 V version is powered by two old 12 V Technic motors which are located in the middle section. Some gears and axles bring the "power" down to the center wheel of the 3 larger ones. Sorry, I had to cut the 3L axle with stop to make it a 2.5L version. The power for the motors and the 12 V lights in the front and rear are picked up by some old power pick-ups from the 70's. Unfortunatelly the resistance of the gears, axles and especially the connecting rods is very high, so the maximum speed of this Crocodile is rather poor. For more speed I need to add a second locomotive with a regular 12 V train motor pushing this engine. I am quite happy with my simple solution to keep the dark grey boat studs in place in the 1x4 arch bricks. At the bottom the vertical boat stud edge is held in place by a 1x2 grille tile. And when the arch is attached this is a nice and sturdy solution. Finally you can see this Crocodile in action over at YouTube: Other 12 Volt MOCs While I had set up a little test loop I took some scences of some more of my 12 V Train MOCs (and the famous #7740) ... enjoy: And don't miss the 12 Volt train powered by Power Functions using 3D printed wheels in 12 V style on a regular Power Functions train motor:

    Bahnbetriesbwerk NeuKriche 2.0

    @Enrico7676 thanks for sharing your work in progress on the Roundhouse and the turntable. Isn't this a masterpiece to build for each LEGO train fan?! Remembering building mine I can say: beware off the size. The roof and the back wall will eat a lot of elements (but it's worth it). And keep room for gaps, you can not measure everything in advance and the copies of your segments might not go together as easily as you might think in theory. Height adjustable tables helps a lot, less pricy then raising everything else then the turntable. Are you going for electric lights and remote opening doors? Good luck and patience with your Roundhouse :-) Holger
  15. @Vilhelm22 and all others, here is my YouTube version of the clip you've mentioned. I digged out some very old 9V MOC rolling stuff and 8-wide and rather simple build engine (all done in the eary 2000's) and gave it a go on Fx Track. About the availability I know that JB Spielwaren is the reseller partner for Europe (including the UK, no idea since Brexit). On fxbricks.com JB Spielwaren is mentioned as official reseller for the EU, hmm. And on fxbricks.com the R72 curves and S32 straights seems to be sold out already. Fx Track is a very, very good third party product, probaly the best I've ever seen. The quality is supereb, starting with the box design and ending when running the trains on it. I started this post here when Michael announced the Fx Track idea at Brickworld 2019 in Chicago. Back then he handed out a prototype piece of the upcoming S32 straight. Compared to that the final product did another major step ahead: better color matching to dark bluish grey, Fx logo on the studs, special identification on the studs about the radius or lenght. Highly recommended! Now I am looking forward to the large switches and for power pickups or motors … (I got my R72 and S32 as review kit directly from @michaelgale, only had to pay the custom and shipping fees)
