Tiny Town world’s smallest "functioning" LEGO Train
The first LEGO Train for LEGO guys to play with! This Micro Scale trainset was designed as a model train for a Minifig to use. The high speed commuter train is approximately 1/360 scale though the buildings are a mix of scales as otherwise some would be too big to fit on the compact layout.
About this creation
The Idea:
I originally got the idea for this after seeing this video:
World Smallest Model train
Now obviously I couldn't make a working LEGO train that small (the whole thing would be a 1x1 Modulex brick!) but it did make me wonder how small I could get a working LEGO train set. I stayed up until 2am pacing the house thinking about how to do it for 3 days.

Laying Track (the build process):
I started building the prototype and after about 4 more days I had a multicolored train on a rotating platform. The platform was very plain and had to be turned by hand as I had no motor. I realized that I would also need a lot of fresh parts to build the scenery around the train itself. The bricklink parts came in in only a few days but the motor and battery box from LEGO took a month to come in. In the mean time I borrowed my friend Marc's AAA battery box to test where to put it in the layout (I ended up using his and just gave him the new one when it came in). Once the motor was in place I had to gear it, which required stealing some gears from my X-Wing's laser cannons. It took me another week in a half to build the layout. The spinning mechanism is made with 4 try-bladed Technical propellers making the whole thing rather delicate. It took me another few days to get it to work as I had to counterbalance the weight of the train or else it would tip toward that side. The trick to the whole layout is the tunnel, the whole middle (and train loop) is held onto the rest of it by the mountain tunnel.

Critical parts:
Power functions AAA battery box (thanks Marc!)
Power Functions M motor
4x Technic, Plate Rotor 3 Blade
Gears stollen from my X-Wing

About the train set:
The high speed comuter train is approximately 1/360 scale. The rest of the layout is a mixed bag, as the scale of buildings vary. I tried to fit a building of each type on the layout.

The buildings:
Train Station
Gas Station (Really like how this came out, though that sign likes to fall off)
House
Factory
Diner (by far my favorite building, I love the milkshake glass I made on the roof!)
Farm
Their is also a mountain with the melting snow forming into a river

Amazing that the whole layout, battery box and all, is only 18x18 studs.

Now that is a cool little MOC. Nice idea making the whole track move. Very clever. I love microscale and I have a soft spot for trains too because it was my sons favorite thing when he was little. You did a great job on this.

Very nice work. I don't think I would have thought to build the train and track as a single piece and rotate the entire unit. Very innovative. The motion is convincing. The train looks great. Top notch model.

Indeed. This is truly a world-class model :-D Its amazing that you managed to fit all that functionality in such a small space; I struggle with at least three times the size :-D Truly astonishing work my friend; I might even try one of these myself....

Quoting Fogtod the Engineer Very nice. Impressed with how much you've crammed into the small space in addition to the train. The mountain, waterfall, farm (if I'm not mistaken), bridge, tunnel, and all the different buildings. The whole idea has potential worthy of more experimentation. (e.g. I'm wondering if a technic caterpillar track mounted on it's side would enable a more complex train track layout.) Inspiration to build more is a sign of a great MOC!
Someone suggested that to me at my local LEGO club. Someone else at the club said that it wouldn't work though because that long a length of tread would have too much friction. I may still try it sometime but I have a lot of other projects in front of it. If you want to do it go ahead as it might be a while before I get to it.

Very creative! The design was well worth the time you spent thinking about it, it is incredibly well made, with all the details such as the train station's tower on/off switch.

a great concept! if you d have used black grills, it d give the illusion it actually runs on the tracks, I agree that it s worth taking further, the scene is also very detailed and beautiful! bravo Scott!

Sweet! That is so awesome. Sure, it doesn't run on the track, but that is really cool. Minifig Scale LEGO Convention, yes? This would be a display with the bulk of it being hidden in the base. Ideas...

I really like it, clever use of parts and innovative approach to small scale dioramas. That gas station looks very lovely and the colors chosen give great impression of realism.
