This MOC was actually completed in one day, the last day I had before a meeting
with some fellow Dutch Lego enthusiasts. If you want to look at the pretty
pictures of the meeting, just do a Brickshelf search on the word “Deurne” (which
happened to be the location of the meeting.)
Anyway, back to the MOC. Since I was working with a time limit the scenery is
not as pretty or as big as I’d have liked it to have been, but that’s also due
to the fact that I was straight out of chain links, so the train makes some
pretty harsh turns. I’m really happy about the train itself, though. It’s built
with a zillertal bahn steam engine in mind (it’s modeled after one of my dad’s
LGB trains, but so far I haven’t been able to track down the make or model,
though) As you may have figured, the train is pulled forward with the two
magnets at the front and back, which work pretty well as far as steering is
concerned. The plate it runs on is a reversed space landing pad, as it’s the
thinnest and smoothest surface I could build with Lego elements. The surface it
runs on looks more like a road than traintracks... but I still think trains look
much better than, say, cars.
Anyway, I’d love to hear what you folks think.

Hi Peer,
I was admiring this model in your gallery and hoping you would post something
about it. I think it is an absolutely brilliant model and idea so
congratulations for both the inspiration and the implementation. Brilliant work!

Cool! That should sort the problem of how to propel 2-wide trains (for those
who don’t have N-gauge track)!

Wow, that’s all very well done! The space baseplate, the magnets, the detailing
on the train itself, et al! And easy expansion for a large layout. And hey... if
you use one of the contoured baseplates, you can have valleys and hills too!
A potential solution to running out of chain links would be to eliminate them
entirely, and use simple thread (lego/non-lego-- up to you) And thread it
through the magnet holder stud. Haven’t tried this myself, but there should be
enough power for the magnet to rise upward on it’s own when you place the train
above it.
BTW how did you attach the magnets to the chain links in the first place?

Using thread instead of chain links is indeed a cheaper solution, and may even
give more curving options. The only problem I’d see is propulsion, thread
doesn’t have as much ’ grip’ as chain links have.

The wide chain link fits snugly inside the technic hole of the magnet holder.
As can also be seen here , which is
incidentally also the set where I got my 4 ‘wide variety’ chain links.

I really like this idea.
I had tried using a chain drive for a small cart ride
http://www.brickshelf.com/cgi-bin/gallery.cgi?i=145541
In my design, I used one of the "fat" chain links to attach a plate, which
supported the cart. I had problems with the plate falling off every so often.
Also, there was a pretty large opening to allow the plate to stick through the
"ground" into the vehicle.
I like your use of magnets instead. How did you mount the magnet to the chain
drive though? I can't figure it out from the pictures.
Thanks

The inverted baseplate is such a simple idea, one question though, do the
magnets have to be pressed up to the underside of the baseplate, or can the be a
little gap?
otherwise, for a days work, wow?

Ah yes, crossposting. I think the concept finally stopped eluding me ;)

There is a little gap between the baseplate and the magnet below, but the pull
between both magnets is so strong that they’ll stretch the chain a little and
come together anyway.

Please do understand that this was indeed a full day; starting at 9 in the
morning and quitting at 6 in the evening. (Including several breaks, of course).
Also, I had been thinking about this project a lot, only to find the time to do
it at the last possible moment. Like a lot of folks, I work best when there’s
some kind of deadline looming. :)

At first I also tried to attach plates to the bigger chain links (at some point
I even considered using glue), but the other option you have is sticking one end
of the big link into a technic hole.
And conventiently enough, a magnet holder also has such a hole. A very simple
and elegant solution (if I do say so myself), and it won’t fall off easily.

A second alternative to specialized chain links -- and one I haven’t tried yet
-- would be Technic link-arms and pins, threaded around large-diameter tires.
The magnet-holders can then be pinned vertically, and the curves in the “track”
aren’t so abrubt.
There might be a problem keeping this chain taut, although there are enough
wheel-diameters available for experimentation. Also, the tire-chain combo
wouldn’t move as smoothly as chain links-gears, so some extra gearing-down might
be necessary.
This is still necessarily 2D -- I’m not sure if it can be extended to 3D (a
track with hills). There might be linkages that would permit both horiz and
vertical (alternative) movement in the chain, but the extra floppiness might
cause it to fall off the wheels.
Now, how to adapt this to a moving sidewalk for minifigs... And I wonder if the
scheme would work vertically? --E.g. a loop of elevator cars moving up the side
of a skyscraper, or one of those sci-fi moving ladders (e.g. “Star Blazers”).
