Oops! Of course, you're absolutely right! I have reworked the bogies to allow them to pass over switches and curves. In turn, I've had to raise the M motors by one plate, and then adjust the roof as well! First, the bogies needed to be changed so they don't catch on points and curves. I felt the old structure wouldn't be strong enough as the lower plate is now missing. The old 1x8 Technic beams were replaced by 4x4 Technic frames. The two short 2-long axles were replaced by a single, longer axle. This forced the drive shaft to the motor to be shorter, and I've changed it to an axle with end stop. The end stop will help keep the bogie attached to the locomotive when I pick it up. The M motor is a weak link, but I think it will be easy enough to re-attach the bogies to the M motor if needed. Re-attaching the gear would be much harder. In turn the M-motor mount has been pushed up: And then, the motor was interfering with the roof so that had to change. It worked out in the end though :).

I really like a lot about this model. The use of colors is very nice and it feels like a fun model to build and play. It's certainly different than most models posted here

I will have a look into creating the Brickshelf account. Meanwhile; bogies! No modern train should be without them... There isn't too much exciting about the 47's bogies; on the outside they use the standard Lego pieces to detail the outside. On the inside however, things are a bit different. All wheels on the 47 are powered, and the bogies should allow for a crazy amount of turning. This allows for tighter turns or longer locomotives. Above is the outside of the bogies. It's a bit plane Jane with Lego's standard magnet coupling and bogie sides. Only the drive shaft sticks out to reveal something unusual is going on. I've also added a bit of detail to represent the springs that hold up the locomotive in real life. There are also a few black plates added to help spread the weight; probably not entirely required. On the inside, things get a bit more interesting. Rather than the same old train engine, the drive shaft connects to a set of gears to drive both wheels. The bogies are constructed so that the gears have the minimum amount of play. I am not too sure about how much torque the bogies will handle (i.e. how many cars the locomotive can pull). I guess that is trial and error. Edit: Oops, forgot to mention the motor mount. Here is the bogie attached to the motor: And finally, the motor mount itself. The M motor is supported by 8 points on its bottom and 3 points on the front. This should be enough to hold the motor.

Hi everyone, Do you know those Russian dolls? The ones that you open up and there's a smaller doll inside? And so on, and so on... That's been the inspiration for this particular trainset. I will get back to that in later posts. I am going to start off with a 6-wide Class 47. A while back, I've posted something about a wider and longer 47. I've scaled it down for this set so it would run better on standard Lego tracks. In fact, it is just about the same size as Lego's own train sets. (Note: Where can I share the LXF file?) I've tried to make the model stand out a bit from the standard Lego locomotive setup (which typically uses a train motor as one bogie). Here it is, undressed: I did build the mechanics in part, and they come together quite nicely. I've modified the LDD file to fix the errors that did exist in the model. The engine is in Dutch livery. A quick look at my username explains why It's also meant to be build in modules: I will make you wait for the other bits of the trainset
