  1. MOC - Garden Toy Train - 12-wide

    Thanks!!! It was inspired from some information I found in internet about custom wagons in G-Scale - allowing tight radius cornering. It is completely unreal , but I have to adapt (improvise, adapt, overcome! ) the behaviour of rolling stock to the worst track case possible. I made no photo but in standard curves the side edges of the locomotive and wagon are veeeeeery near. Basically I'm trying to make what looks like a metric gauge train to run on a Decauville track radius. The locomotive is still in 2wd mode with rubber bands on traction wheels - I have the new chains, but I did not install them yet Bye! Davide
  2. MOC - Garden Toy Train - 12-wide

    Hi @zephyr1934 , thank you! - After a week without working on the big train, I prepared a prototype wagon to test the new couplings and the axle-steering system - I can confirm the simple coupling works fine, and it is a decent way to keep rolling stock together. It also has a bit of flexibility, which is not bad. So, let's see how it works: First case - switch with straight line track (also valid for switch with one straight and one curve) - this is the optimal track solution to help the axles and the couplings in doing their work. Second case - original Lego track geometry with counter-curve after the switch (harder to manage, but very realistic in this big scale - two trains can cross each other without touching, and they are very close. Now, let's take a look to the steering system on the wagon: It is the same used on my yellow wagon - I used big wheels, but also BBB medium wheels can be used without problems. The steering pivot of the coupling is quite far from the coupling itself, but it allows a good, decentralized movement of the coupling from side to side. The steering system works as you can see in the pictures, the coupling actually steers a bit more than the axle. The fake suspension used for locomotive is replicated also on wagon and covers quite fine the wheels. The first picture shows wheels spaced to work on standard Lego gauge , in the second one you can see the wheels positioned to work on 45mm G-Gauge. Probably I'll rework the fake suspension to look like a leaf-spring type instead of a double-spring type. And this is how the wagon manages the second type of track geometry: Locomotive is travelling on the switch - this is the most critical moment: locomotive coupling is quite at its maximum articulation and brings the wagon steering to move a bit in the opposite direction. This is a problem of the locomotive coupling pivot, which is too near to the chassis end. But I cannot move it, there are batteries and motor on the other side - so I have to accept this. ...at least the unwanted turning movement is mitigated by the linked steering (so wagon wheels are not steered too much to touch the rail with borders. Step two - the wagon is managing the switch, axle is turned according to curve. Step Three - the locomotive is now on the straight part of the track and pulls the wagon in the right way - axle is steered to follow the curve (maybe a bit too much). It seems to work both pulling and pushing - I'm not satisfied 100% by that unwanted steering - I'll try to move the axles inwards by one stud and to make the steering links a bit longer (4 studs instead of 3). I tried also to put the locomotive red body (the "prototype") on the wagon chassis - it is quite heavy, but it is pulled without problems. Wagons will surely be lighter than the locomotive, since the bodies will be 1-stud wide instead of 2-wide. Last but not least...an S-Brick arrived as a gift...now I can drive a blue....tooth locomotive . Bye! Davide
  3. Use ofLlego motor 6216m2

    Yes, it is possible, it is compatible with all Technic parts, you only have to deal with the specific voltage and with a bit of downgearing to achieve some more torque

    I like it a lot!!! Small, very good use of internal space, realistic colors...thumbs up

    It is a very nice realization!!! With time and patience you will also create it in real bricks and then you can add or modify details - and it truly is another level of satisfaction I simply can not leave unanswered one your nice signatures: "The way I see it, if you're gonna build a time machine into a car, why not do it with some style?" Ciao! Davide

    Hi @Bartosz, sorry for delay, here it is the .lxf file: https://www.dropbox.com/s/w6ku042a9hx35lh/4564.lxf?dl=0 Good work on your 4564!!!

    That "nose" is amazing - it perfectly imitates the shape of the original locomotive!!! Well done!!!

    Wagon chassis will surely tested with a cocktail on it - I put this test on the list!!! maybe too fast - I tried other gear ratios - but until I'm not sure on how much the wagons weigh and stress the transmission I cannot tell which is the best one I love trains with nature background - it is somehow relaxing!

    Thank you!!! I think the track, with a bit of "terrain preparation" (e.g. bricks and plates under the track to cover holes) can be manageable - let's see the weather during weekend! In the meantime, I'm studying how to manage couplings and the wagons behaviour on R40 track. This is the new buffer with coupling system I want to share with you - for comments and suggestions; The buffer can turn left and right - together with the coupling. The coupling can be folded up when not in use (the buffer must be removed and put again in place) Here above it is in extended position. Here below, the prototype of the two- axle wagon is ongoing - the buffer is turning like the locomotive one - but it will also turn the wheels (I found some solutions of G scale wagons with two axles adopting a similar steering system). The coupling is easy to perform - even if it is the most unreal thing on earth - turn one buffer right, turn the other left - connnect the two couplings with the 3L axle. Each wagon will have a place to store the two 3l axles (only one should be used, the other one is a spare part) I know it is an idiotic way of coupling , but it is simple to build and, for the moment, it seems to work (and keeps the two buffers attached). I'm planning to adopt a steering linkage like the one used in the below wagon (prepared some months ago for the castering effect study) which is very similar to the G gauge solutions I saw around. Since there is some overhang from buffer to wheels, I think the wheels and buffers of these big wagons cannot be turned by the same angle - since you could have an axle which is turning too much, even if in the right direction. Doubling the size of rolling stock creates a double amount of problems when it comes to manage a track radius which already is narrow (now it is narrower by two times). I found especially difficult to manage narrow S curves (left track + right track o 2 left track + 2 right track). This evening I will prepare some photos to show you how the buffers are "stressed" during an "S" curve. I do not want to think about specific track geometries accepted by this rolling stock until I try all the technical possibilities to manage the R40 radius properly Ciao! Davide

    Nooooo problem - not disappointed at all - I'll try to search them here on EB !!!

    Thanks!!! You're right, they are quite unaccessible - I think I'll attach a bar on them - I want to experiment a coupling like H0 ones, but I still don't know I'm just building a wagon to test the behaviour of rolling stock during curves and switches

    Hi all! Parts arrived - and yesterday I had the chance to build the big blue locomotive. Since today was a really nice day, I prepared some track in our common garden and took some shots. I prepared also a video - pity it's only from outside , since I pressed the wrong button on the "driver's view" microcamera - so basically I turned it off instead of starting the recording . At least we spent a good afternoon with other neighbours and childrens!!! The pictures you see are only for show purpose since the track, simply placed over grass, is hard to manage for such an heavy locomotive - it wobbles left and right and in some cases it falls on its side. Now I understand the importance to prepare a properly plain garden railway track. Pity I do not have my own garden...but who knows... Creating some kind of track base (using wood for example) could help to solve the stability problem. As you can see, there are some differences from the red prototype and LDD projects: I kept the chain drive, but I used normal gears instead of yellow knob-gears. It drives more smoothly now. I increased the gear ratio a bit after some testing. No problems from chain drive for the moment. One of the bonnets was modified to accept IR receiver - which works quite fine. An S-Brick would be better, but for the moment I'll keep the IR solution. Side door handles were reinforced - they falled off easily - and this is not good in the garden "environment" There are no glasses on front and rear windows - the ones I received were basically no more transparent. It still is 2wd, I did not receive the chain parts yet. With two (old) red rubber traction bands things get better. In this photo the bands are not pictured since I put them on after a while. Now it is time to figure out how to make wagons work properly - the R40 radius is reeeeeeally tight and the locomotive has a significant overhang when going around a standard Lego curve. Hope you like it! Video coming soon! Ciao! Davide

    Lovely real life Thomas!!! I like side decorations a lot!!!

    Woooow!!! Nice, nice nice - the stickers, the wagon, the "electronics", the details...everything is spectacular . Even if it is a replica, you surely put a lot of added value. I like this "European Tour" initiative - I wonder what will come out for Italy! I'll patiently wait !!! Ciao! Davide
