And now for
Something Not Completely Familiar (SNCF)
by Carl Arendt
[This layout was designed and constructed for
a competition run by the English magazine, Model Trains International. The
requirement was to produce a working model railway layout in an area the size of
an A3 sheet of paper or its equivalent, two A4 sheets -- about the size of two pieces
of U.S. letter paper laid end to end.]
The first issue was scale and gauge. My objective as usual was to use the largest
possible scale in this miniscule space, just to prove it can be done!
I took a look at G scale, metre gauge (1:22.5 on 45mm gauge) and decided that these
trains were simply too large to build a working railway in the available area. (I
hope someone will immediately prove me wrong!) Gn15 can provide a solution in the
same scale using small industrial or estate-type trains, but several of my companions
in Gn15 modeling were entering such layouts so I decided to try something different.
The challenge of attempting to stuff a very large scale into this pint pot continued
to appeal, so I thought about 1:32 scale. Interestingly, O gauge track -- 32mm --
is almost exactly a scale metre wide in 1:32! So I doodled to see what might fit
in 1:32m. The best I could do for a working railroad plan was a sector plate feeding
two sidings. Not exactly a jackpot of activity!
But then inspiration struck. I remembered an immortal line by the dean of American
layout planners, John Armstrong, who once wrote: "You can live close to town
and still have it seem like a long way home if you have to change cars ... and that's
the stunt that we use here to make up for lack of a ... mainline run in our restricted
space."
So I used 16.5mm track to make one of the sidngs into a 500mm gauge industrial line
that would exchange cars with the metre gauge line. Voila! an operating scheme appeared!
By this time I was firmly fixed on settng the layout in France, a spiritual home
of metre gauge trains... so for added fun I made the industrial line electric, once
a common sight in France. And in order to exchange rolling stock, we needed some
dual-gauge track -- so the industrial siding acquired four rails, concentric metre
and 500mm gauges. Compared to three-rail solutions,this kind of four-rail dual-gauge
track simplifies coupling narrow gauge locos to metre-gauge wagons, just as it does
in the prototype.
Now things were beginning to get interesting! The plan at at this point looked like
this:
The
operating scheme would see a metre-gauge locomotive (which turned out to be a casual
railcar) deliver a wagon loaded with supplies for the rural factory. It would leave
the car on the sector plate and retire behind the poplars. The narrow gauge industrial
switch engine would then advance, couple to the metre-gauge car, and pull it forward
onto the dual-gauge industrial siding for unloading. Later the process would be reversed
to return the empty car or to ship a load of the factory's (unspecified) products.The
whole thing could be very Gallic -- and so it worked out (below). |
Unfortunately, one result of being unusual is that you have to do a lot more work!
In this case, there is no commercial rolling stock available for 1:32m, and very
little for 1:32e (500) either. So I had to make it all from scratch. In the event,
I built three pieces:
1.
a metre-gauge Billard railcar, built from a photograph on the back cover of Gordon
Gravett's wonderful book, "Reseau Breton" from styrene sheet material on
a motor truck from a defunct Lima British Rail Bo-Bo diesel model in O scale;
2. a 500mm gauge "saltbox on a flatcar" trolley work car, narrowed
from an industrial line in Grenoble and designed from plans in Voie Libre
magazine, constructed of styrene sheeting on a Bachmann On30 trolley motor truck
(and using the Bachmann trolley pole); and
3. a simple five-plank four-wheeled metre gauge wagon made from a photo on
the Internet of the Bay of the Somme railway in northern France. This little line
also has four-track dual gauge trackage, in this case standard gauge enclosing metre-gauge
rails. My model is built on a Slater's O-scale wagon chassis kit.
In all three models many details remain to be added. In fact, taking these photographs
reminded me that in my rush to beat the competition deadline I neglected to glaze
the work trolley!

I also experimented with an unusual material for a layout base -- florists' foam.
It comes in one-by-three-foot sheets in half-inch increments of thickness from 1/2"
to 3". I used 1" thickness, braced with cross stringers of 2" pink
extruded foam insulation board (above). Verdict: the material is strong enough,
but does not hold trees, poles, and other objects very tenaciously. I probably won't
use it again.
The foam does, however, have the advantage of very light weight. The entire layout
-- with scenery -- weighs 1.5 pounds -- and that includes the foamcore backdrop and
skirting which are not actually part of the layout but simply make it look nicer.
The skirting and backdrop are removable to slim the board down to competition size
-- 210x594mm (left hand photo).
For layout scenery, I tried another unusual device. I ransacked the holiday albums
of my friends who have visited France, and found one who had hired a farmhouse in
Normandy last summer. Her photos included some very attractive landscapes and a couple
excellent shots of typical local cottages. Her gite was called "Les Peupliers"
(The Poplars), so that became the layout's name. The cottage and barn were added
to the backdrop (at the right side, somewhat hidden by a row of -- you guessed it
-- poplars). The original digital photos were resized on the computer, printed out
to size, and added to the backdrop to blend as gently as possible with the layout
landscape.
I carried this photographic borrowing to an extreme by making a foamcore
shell and covering the walls with computer-enhanced photos of another Normandy cottage.
I added a tile roof made from one of the corrugated-paper cartons in which light
bulbs are sold.
This "instant 3-D model" scheme, borrowed from stage set design, also created
a separate little "activity area" at the front left corner, shown in closeup
at the left. A dog is examining the remains of today's Le Figaro with an eye
either to read the news or to use it for more utilitarian purposes.
Other layout details are commercial products from Messrs. Bantock & Lantz and
K-Line Standard Gauge. The trees were made from dried weeds bought at a craft store
(impossible to find them outdoors during mid-winter in Pennsylvania), sprayed with
glue and covered with green flocking from Woodland Scenics.
All in all, I'm pleased with my journey into the unusual -- it was a real challenge
to my ingenuity! I think the atmosphere of rural Normandy comes across, although
much detailing remains to be added after the contest deadline (especially the tall
grasses that are so abundant in this part of Normandy).
In practice, adding a small post-competition fiddle yard at the east end would be
helpful in creating more realistic operating patterns. This very large scale modeling
does represent an attempt to stuff about four litres into a pint pot ... and after
the big trains are put on the rails, there's not a lot of travel space left! The
recommended fiddle yard will ease congestion a lot. The resulting layout is still
slightly smaller than a three-foot bookshelf.

Allons! Let us now operate les p'tits trains, mes amis!
The typical operating pattern of Les Peupliers
looks like this: |

1.
Starting position: metre gauge train at right rear; 500mm electric switcher in pocket
at right front. |

2.
Metre-gauge railcar pushes wagon to sector plate behind cottage, then uncouples to
retire behind poplars. |

3.
500mm loco moves over and couples to metre-gauge wagon, ready to pull it from sector
plate. |

4.
Electric switcher pulls wagon over dual gauge spur to unloading point. To reset,
just reverse this sequence! |
