Lots of free building instructions with part lists here, mostly Danish locomotives and rolling stock

Finally, the platform is finished and ready to be packed before going to Skærbæk Fan Weekend tomorrow Unfortunately the slight v-angle of the roof had to go as it was too fragile and prone to slowly dropping down due to gravity. A "not-so-uncommon" problem with digital designing, no gravity that is At least the roof is now much more solid and overall flat from module to module and with fewer parts. The platform (without minifigs the and other scenery): My DSB IC3 passenger train on the intercity side: Now that the "easier" part is done, the next stop is the train station itself! 99% of the parts have been collected, I just need to find the time and even more important the space: The platform with tracks is about 1/3 of the overall layout

And running full speed I barely understand the basics of the home made control system used for most of the layout but yes, it is very sophisticated and 9v powered. I’ll have to ask the guys for a better and more elaborate answer. -

Thanks! It is not mine as I haven’t made a steam engine yet (still working on my first one). i’m quite sure it is made by our chairman Lars Mogensen but far from all of his train stuff have been shown online or even have pictures of them at all. Unfortuantely this seems one of those. His old Brickshelf gallery here and Togklodsen’s still rather sparse gallery here. . -
Video from the yearly model railroad exhibition in the danish city of Helsingør earlier this month. The LEGO contribution was done by our new (and smallish) train club, Togklodsen. Unfortunately I couldn’t participate but a lot of my trains did A rather spectacular crash occurs around the 12 minute mark

The first part of the project, the platform, being built for Skærbæk Fan Weekend 2019

Presenting another Danish wagon...a design-project for another Danish LUG-member to build and test in real bricks (!) DSB Litra DB (II) The Danish State Railways' (DSB) improved Litra DB (II) travelling post offices (TPOs) were built by Scandia in Denmark. 5 were built in 1961. All have been scraped today, the last one in 2011. The model: Digital but has been built and being tested irl with free bulding instructions also in the works Original DSB maroon livery used from the fifties to the seventies - with Dark Red a very good match albeit a bit too clean Scale: ~1:50 Lenght: 34 bricks Width: 7 bricks Bricks: 808 (very heavy, so ball bearings recommended) Designed: 2012 & 2017 & 2019 Sadly the LEGO Digital Designer file was lost a few years ago when all my data were lost (including multiple backups). So I had to recreate the model from scratch using two remaining screenshots posted online. Rather strange experience to reverse engineering yourself Very high setting render from Stud.io with custom decals done in the PartDesigner tool and some manuel editing. The roof can be removed, giving access inside the wagon and the doors can slide in opposite directions by flipping the blocking hinge parts down. Technique used for the bogies - prepared for ball bearings Maybe some photoes of the real thing will be added later when completely done...

As a general LEGO fan I really like this set but as a LEGO train builder not so much. Too many design compromises and those new wheels still don’t win me over even in red.
-
And as espected the first comparison doesn’t show the new wheels in a positive light. Shame on you LEGO
-
Much better 🙂 Fellow Danish LUG and Eurobrick member Esben Kolind designed some Jacobs bogies serveral years ago for his Öresundstrain with flexible connectors and rubber bands being pulled apart in curves and pulled closer on straight tracks. Unfortunately this required unavailable space on my train - otherwise I would probably have (ahem) borrowed his solution 😁
-
I definitely agree but unfortunately the placement of the train motors as Jacobs bogies proved the better PF solution in practice than having the train motors placed in the far ends. The weight of the battery boxes gave a much firmer grip and didn’t require lengthy cables running underneath from the train motors in the far ends to the battery boxes in the mid-unit. A fragile and prone-to-break pin solution spaced a bit closer together was used at first for the Jacobs boogies but the more robust-but-farther-apart pin solution chosen proved far superior in that aspect. Almost unbreakable 😁 A turntable instead of a pin would block the power cables behind the train motors from being pulled up (towards the free pin on top of the train motors) and through a hole in the doors in both ends of the mid-unit. Also a pin through a 1 x 1 hole is an easier solution for a 7-wide base than a turntable. I hope this makes sense without a picture 🙂 Brick-built and better-looking Jacobs boogies could have been used for the 9v version but my goal of using the same basic building teamplate for both versions (needed for the instructions) killed that idea. And all boogies on the train are identical anyways. Make no mistake, I would have loved a better-looking solution too but couldn’t find any without serveral drawbacks and so simplicity and durability won out in the end 🙂

Not really a problem, as the IC3 is more built for quick accelerations and smooth stops (then all-out speed) suited for the short distances between stations in small countries like Denmark. Top speed is only 180 km/h or 111.85 mph.
-
Thanks! Suction is more or less the idea From wikipedia: "The front- and cab-design is the most significant feature of the IC3 (and its cousins). When viewed from the outside, the viewer will notice the large rubber diaphragm surrounding a flat cab. The cab is separate department in the train, but the table with the controls are mounted on a huge door, to which the seat is also mounted. When two or more units are coupled together in a single train, the entire front door folds away to give a wide passage, and the rubber diaphragms at the ends form a flush aerodynamic seal."

Presenting another Danish train... DSB IC3 The Danish State Railways’ (DSB) highly successful and innovative InterCity 3 (IC3) passenger train was co-developed by Siemens Duewag in Germany and ABB Scandia in Denmark. The train is operated by DSB in Denmark and Sweden, by Renfe Operadora in Spain and by Israel Railways in Israel. Amtrak in the USA and Via Rail in Canada have tested the train in the past. A trainset consists of three units, two diesel motor units (MFA and MFB) and one intermediary unit (FF). Up to five trainsets can be coupled together. 96 trainset were built for DSB from 1989 to 1991. All are still in service today. My model: Room for lights in all headlights and interior. Scale: 1:50 Lenght: 140 bricks (MFA 46 bricks - FF bricks 40 - MFB 46 bricks) Width: 7 bricks Bricks: 2.084 (9v) or 2.079 (PF) Powered: 2 x 9v or 2 x PF train motors with 2 x battery boxses Designed: 2017 Digital model but built by me (and many others) irl Very high setting render from Stud.io with custom decals done in the PartDesigner tool. Free building instructions: DSB IC3 9v variant here DSB IC3 PF variant here DSB original white and red livery of the 1990-2000s: View from the side - unfortunately the wide gab between the units is necessary to run through R40 curved tracks smoothly: Access to the interior with seating for 54 minifig passengers, 2 train drivers and additional space for 2 bicycles, standing passengers, stewards and 2 toilet guests: FF unit (PF) with 2 IR Receivers, 2 Battery Boxes and 1 Polarity Switch: Technique used for the sliding toilet doors - turning the Pneumatic T Piece 90° behind the seat keeps the door shut when closed: Youtube video from fellow Danish LUG member Knud Ahrnell Albrechtsen:
