    Trains in 4-Wide

    I have started building a motor block with battery and hub inside my 4-wide RhB Ge 2/4 shown earlier. I needed to rebuild my prototype motor block to be one stud longer. So far I have used 4262 Technic, Plate 1 x 6 with Toothed Ends to hold the drive wheels in place but I have since tried 32063 Technic, Liftarm Thin 1 x 6 which gives a much stronger connection. I may have to switch to 5L Technic axle as the wheels keep coming free from the Technic Plates / Liftarms. The whole body rests on a 2 x 4 plate between the two motors (circled in yellow). I will have to rebuild the entire body to fit around the motors and Circuit Cube hub/battery box. At the moment the hub/battery box is at one end of the loco, but to hide that behind tiles means I lose the door features, so I may have to move it between the motors, or lose one of the motors. I'm reluctant to lose a motor because that would mean only one powered axle, but to keep two motors with the cube in between I may have to move the drive axles another stud further apart. The pony trucks pivot on more Technic Liftarms held on place by the drive shaft from the motors. The loco as it stands runs around the test track nicely, but I haven't finished the motor train design yet.

    Class 91 - LNER Livery in 6 wide (WIP)

    I think we need a picture to pass judgement! :-)
  4. Currently new offered for £21.99 + £2.89 postage for UK buyers, see here https://www.ebay.co.uk/itm/233609481151 Even less if you buy more than one. RRP is £69.99. I have no connection with this seller. There are other sellers with similar prices. I bought one just to make sure and it is the genuine article, sealed bag, put batteries in, connected it to powered up app, it upgraded itself and then ready to go. I tested it with lights and train motor no problems. I think they are a bit big for a loco unless you build 8 or 10 wide, but for a ground mounted hub for light signals and point motors this is great value as it has 4 ports (and built in sensors).

    Trains in 4-Wide

    Thanks @XG BC for your very clear explanation. I'm not sure everyone can build 8 wide models, but I do agree that modelling 4 wide trains is an art form!

    Brilliantly done. To get the right number and size of windows in this scale is quite an achievement. As I am a beginner, can you explain why you needed to build 90% upside down? Are the wheels able to articulate? With that length of wheelbase I don't think it would go around R24 curves. Or is it a display model? Again, great models.

    Thanks @zephyr1934 that tip about wiring the motors in series from one port will make it a lot easier to control. Ref hiding the cube, my model is already 4 + 2 x tiles wide (so not strictly speaking 4 wide) so hiding with tiles is probably the way I will go.

    Trains in 4-Wide

    Not sure if I should create a new thread for this but I've started so I'll finish! As I said I earlier (2 posts back) I was going to order a Circuit Cubes motor and try to motorise my 4-wide model. The Circuit Cubes Bluetooth set arrived today, so I had a go at building an 0-4-0 train chassis to see how it all works and if it has the power to drive a loco on narrow gauge track with/without any rolling stock behind. Here is my first crude attempt. Side view Under view Front view I had to use two motors, one didn't really have enough power. I've tried to minimise any transmission loss by connecting each motor almost directly to the axle. A couple of videos, one as "light engine" and one pulling a coach. https://www.flickr.com/photos/194726814@N08/51989867092/in/dateposted-public/ https://www.flickr.com/photos/194726814@N08/51991139174/in/dateposted-public/ This test is a challenge with the R24 narrow gauge track curves and the 4 axle coach. My thoughts so far: Like a dog walking on hind legs, the wonder is that it walks at all! This is showing max speed so it's a bit slow but maybe not unlike real narrow gauge locos(!) - I'll try and work out the scale speed. The loco slows down considerably pulling the coach, understandably. I doubt it could pull more than two coaches of this size, but I will test it later. However although it is slow there is not much difference in speed on the straights versus the curves, which was a pleasant surprise. The motors were not as noisy as I had been led to believe, no worse than Lego train motor really. The motors as positioned are only two studs wide so no problem hiding those in a 4-wide body shell, but the Bluetooth receiver/battery box will be quite tricky to hide. Not a bad start. I did most of the test in "battery mode" where you just switch on the Circuit Cubes controller and off it goes at full speed. I did have a go at setting up a custom controller in the Circuit Cubes app. I didn't spend long on this, so the simplest way I found to drive two motors at once (they were on ports A and C) was something like this. There is a coding option but I haven't found any instructions for that so far.

    Motorising 0-6-0s - LEGO Caledonian 812

    My 0-6-0 Powered Up tank engine has two powered axles and the third driven by coupling rod, and the middle axle was blind driver. However I used a Technic large motor not the train motor. I didn’t have any issues starting on R40 curves but it did go slighty slower. https://www.eurobricks.com/forum/index.php?/forums/topic/189724-moc-zillertalbahn-uh-class-0-6-2-tank-engine-6-wide/

    Trains in 4-Wide

    Thanks, I've ordered a Circuit Cubes set and I will have a go at motorising this model in the next few weeks.

    Very nice. I love the red and cream livery version. I think that is the current livery on the Mariazellerbahn?

    LEGO LMS 4F

    Very good, at first glance i thought it was an O scale manufactured model. Do you have any more pictures on Flickr or elsewhere? How does it run with the Circuit Cubes motor? I imagine you need to run on wide radius curves not R40? Thanks for sharing.

    Trains in 4-Wide

    I thought I would have a try at a 4-wide loco. The loco I chose to model was one of my favourite Rhaetian Bahn locos, a Ge 2/4. (from Wikipedia) The scale I chose was based on the track gauge; 4-wide track is 22.5mm gauge which when compared to standard gauge 1435mm gives a scale of 1:64, otherwise known as S scale. The dimensions of a Ge 2/4 are: length 8.70m = 136mm @ 1:64 or approximately 17 studs width 2.65m = 41mm @ 1:64 or approximately 5 studs height 4.05m = 63mm @ 1:64 or approximately 7 bricks Here is the model, basically sticking to those dimensions. It was made mostly with parts from a Crocodile. It's actually 4 studs plus 2 x tiles wide (38mm) which is a bit narrower than it should be. It doesn't look too bad with a minifig. It runs fine on R24 curves due to the ball and socket joints for the pony trucks. I am too old to ever say never, but I think it would be virtually impossible to motorise this with Lego components, even if you put the hub/battery in a trailing car. The pantograph is a bit of a cheat. The light-blue-grey bars which form the frame of the pantograph are normally 3L but that looked way out of scale, so these are 2L which does not exist as a Lego part. I found that the pin used to hold track pieces when shipped in sets is basically a 4L bar with a cap at the end. I took a razor saw to four of these, cut off the cap then cut the remaining 4L bar in half to make 8 x 2L bars. As a "by the way" I found a way to ballast the Lego R24 curves. I really need some 1 x 2 red-brown tiles! Finally I made a coach for the loco from a 40518 set (the 4-wide Intercity train) by using the pieces from the driving car to double the height of the coach. To make it run on curves you would need to mount the bogies on 2 x 2 turntables. It was an interesting exercise to make a 4 wide model, and I think I have captured the essence of the prototype. It is a challenge to provide any level of detail. If you think about it, the "granularity" of Lego, about 3mm (width of plate) translates at 1:64 scale to about 190mm or 7 1/2 inches! However I do like the look and feel of rolling stock this size, and if I could find a way to motorise it I would be happy to work in this scale. Having said that, it would be a whole lot easier in 6-wide. If you built it the same way, 6 wide plus 2 tiles or 54mm that would give you a scale of about 1:48 which in turn would be a length of about 22 studs. With that length you could get a more realistic number of side panels, and operating coupling rods rather than dummies. It would be a doddle to motorise using the standard Lego train motor.

    TrixBrix R32 Curved Track

    My two Lego City trains slow noticeably around R40 curves so that's going to be more noticeable with R32. I haven't tried it but I imagine they would stall on R24 curves at lower speeds.

    Very nice detail and great colour match to the prototype!

    Train stuff on Ideas getting approved? Forget it!

    Stand alone couplers are also useful as buffers are not always round, and narrow gauge railways often have one central buffer because of the shorter radius curves they encounter.

    Train stuff on Ideas getting approved? Forget it!

    I'm sure I've seen (magnetic) couplers without bumpers/buffers. I'll have a look on BL. Or perhaps you mean they already have but you want them to make new ones. Sorry if I have misunderstood, blame it on me being a newbie. EDIT Here: (#2920) https://www.bricklink.com/v2/catalog/catalogitem.page?P=2920
  18. Following demands from my grandson, I have had my first go at a steam loco. I visited Austria in 2017 and went on the Zillertalbahn from Jenbach, and was pulled by No5 Gerlos which is a Uh class 0-6-2 tank engine. I quite liked the look as it was a bit more chunky than the more common U class locos found on Austrian narrow gauge. Anyway here is the prototype (my photo) ready for off at Jenbach in 2017: And here is my model. It has a standard hub and a Technic large motor inside: This is how the motor and hub are organised. The cab sides hide the hub, and the side water tanks hide the motor. You can just reach the hub on/off switch through the cab windows. I need to tidy up the colours behind the wheels and to try and hide the cog wheel but I'm not sure how at the moment. The bodywork is a plate too high which I think I can fix. I would like to put some "brass" trim around the steam domes, what is the nearest colour to brass anyone? I must get around to making something for these locos to pull...
  19. Yes thanks @XG BC I agree smaller wheels would look better, especially as it is meant to be a narrow gauge loco. I could get some of the smaller Big Ben wheels but for the time being I'm happy being a "purist" and living with the compromise. As I get more experienced I may broaden my horizons! Thanks @zephyr1934
  20. Good idea thanks I think I've got one of those somewhere
  21. Nicely done @Selander
  22. Thanks @Murdoch17 much appreciated. Your suggestion for the brass trim on the steam domes is excellent.
  23. Thanks, and good point. I think trying to fit a technic hub in a 6-wide train would be a challenge, but it would be very useful for directional lighting and two motors etc.
  24. Thanks for the explanation @Lok24 and you didn't have to shoot me! :-) Using that number bb0892c01 there is a new one from a UK seller for 23.50 GBP which is half the Lego RRP of 44.99 GBP which is pretty good saving! If I'd known about this a few weeks ago I could have saved myself about 100 GBP. Lesson learned.
  25. Well that is weird, thanks @Lok24 I was just going by the Lego shop item number. https://www.lego.com/en-gb/product/technic-hub-88012 As a newcomer to all this, how do you get to know that 88012 is a set not a part? Or will you have to shoot me if you tell me? Is there an equivalent part number for the standard hub 88009? Thanks
