Hey,
Some years ago I had my first attempt at modelling the Copenhagen metropolitan
S-train (4. generation) (Brickshelf folder). At that time, I was quite happy with the result, I recall,
but looking back on the model now, I’m not quite satisfied with neither the
front nor the curved sidings (well, that’s pretty much all of the train!)
With the introduction of the (1->2) x 6 Slope Brick Curved (Couldn’t find it on
Peeron?) and some new ideas for close coupling and curved sides, my new version
2 almost built itself:
All the pictures in the Brickshelf folder. Reference pictures are found
here.
The curved sides:
The S-train has a very distinct curved shape along the sides, which is hard to
model with any rounded bricks I could think of. So I chose the easy way,
building the walls two studs wide attaching only the inner line of studs to
create the curve.
This picture
really shows that the sides are in no way vertical! In fact, the train is 7 wide
near the roof, 8 wide under the windows and 6 wide closest to the track. The
construction can be seen in detail
here and
it is not as fragile as you would think (allthough it’s not a robust train
either...)
The skeleton:
The curved sides made it difficult to use a regular train base plate. Instead,
the sides and roof are mounted as a shell on top of a two studs wide skeleton as
seen here. The simple structure saves weight and works well with the close coupling
system.
Close coupling:
The S-train comes in two versions with either four or eight small “cars” per
unit. Apart from the front car with two wheel sets, the cars have only one set
of wheels each. Thus, the LEGO model has one 9V engine and only three wheel
sets. The cars rest on each other so to speak, which provided quite a challenge
when designing the close coupling. The
solution works very well in practice as can be sen in the two movies of the
train running (in the Brickshelf folder).
That’s about it. The decals add the final touch, I think.
PLMKWYT, all comments are welcome.

| (...) You mean these? (2 URLs) Sometimes it's easier to lookup a model that you know has the part you need, and look over the inventory. snipped (...) Your train rocks. A great combination of techniques. I really like the CC solution. Mat (18 years ago, 14-Mar-06, to lugnet.trains, FTX)
