Continuing with the theme of "Dual Gauge Without
Tears," the Waterslide Transfer Co. represents one of those busy places
where standard- and narrow-gauge lines meet to sort and trade freight, organize themselves,
and then haul the goods away to freight yards to be marshalled into trains headed
for distant destinations. Transfer stations are (or rather, were) very busy places,
and we've chosen to model the heart of the facility, the Transfer Dock itself.
Top and bottom tracks, which both serve the Transfer Dock, are dual-gauge (three-rail)
affairs. Both tracks are served by central narrow-gauge trackage, which allows you
to have nice, intricate dual-gauge effects using standard HOn3 turnouts (points).
No extra frogs to cut! Notice that the narrow-gauge portion is next to the dock at
both top and bottom -- which means that the third rails are on opposing sides of
the two tracks.
Cunningly concealed within a freight warehouse facade is a dual-gauge transfer table
(traverser), long enough to hold a switching locomotive and two 40-foot U.S. freight
cars (or 3-4 four-wheel European wagons). The table is used to move cars from track
to track, and to "fiddle" cars on and off the layout using the "0-5-0
switcher." Your actual switching locomotive should be narrow gauge so that it
can go anywhere on the layout and can shunt both standard- and narrow-gauge stock.
Notice that the transfer table has four rails--needed to align with both standard
and narrow gauge in the top and bottom tracks. And that's one of the little "catches"
that keep you wide awake when switching this line! The top and bottom dual-gauge
rails are not symmetrical--at the top, for example, the narrow-gauge rails line up
with rails 2 and 4 on the transfer table ... but at the bottom, they're alligned
with rails 1 and 3. So if you want to shift a narrow-gauge car from bottom to top
(or vice versa), you have to get there via the center narrow-gauge trackage, selecting
the correct alignment when you enter the transfer table! A very tricky operation,
in a model or a prototype situation!
Notice also that the narrow-gauge trackage is arranged to provide two runaround areas,
using the transfer table. You'll find this capability very handy as you switch the
cars around the layout. Indeed, Waterslide Transfer is ideal for Car Order operations
-- sequences which order the car to a series of positions on (and off) the layout.
One easy way to handle this task is to have a series of 3x5 cards on which a destinations
list is printed --- along with a paper clip that slides up and down the side of the
card, spotlighting one destination at a time. Grab a card assigned to the boxcar
you're working, pull a destination list out of a hat, clip the two together, and
proceed to switch the car to the next location on the list. Then move the paper clip
down to the next destination on the list and return the card to the hat.
Things will get intricate very quickly, and you'll find yourself spending many a
happy hour shuffling stock around the Waterslide facility, as you hectically forward
the freight to the waiting world!
{Note: If you prefer to model a dual-gauge facility in HO/HOn30 or OO/OO9, use
Peco trackage and follow this same plan. Or add a third rail to N gauge trackage.
Should work just fine!]

Carrying on our theme of "dual gauge without
tears," Jon Songøygard from Norway has designed Sewett's Mine
to take advantage of commercial dual-gauge track offerings from Tillig. As Jon explains:
"The German manufacturer Tillig offers tracks for the combination of normal
(standard) and narrow gauge (H0e - 9mm). See [attached] drawing of the track pieces
necessary for this layout.
"On this layout plan, I've drawn the Tillig
tracks with their original length. If I should build this project, I'd trim off as
much as possible from the three pieces, to give more room for the [gradients] on
the hidden tracks.
"This layout consists of two scenes; the industrial area with the smelter (to
the left), and the ore mine with its desolate surroundings (right). The two scenes
are separated by the hill/mountain, which should have some height to give a majestic
impression."
Jon envisions two trains -- one standard gauge (two ore cars) and one narrow gauge
(five ore cars) -- operating continuously on this layout. The premise is that the
five carloads of slimgauge ore will just fill the two standard-gauge cars. Jon has
drawn the same train at each end of his plan, to show how the trains will fit at
both termini, but only two trains are in operation at any given time.
Starting at the right-hand end, a heavily-laden narrow-gauge train (either 9mm or
12mm gauge, Tillig makes both) emerges from the mine tunnel and parks above the ore
transfer bins. A short time later, a standard-gauge train arrives down below the
bins, and the five loads are transferred. The wider-gauge train pulls away first,
creaking into the tunnel. Ultimately, it arrives at the upper track of the smelter
on the left, and the first car is placed above a transfer bin, as shown. Both cars
are emptied into the bin.
After awhile, a tiny narrow-gauge train of empties pulls out of the smelter and positions
itself beneath the transfer bin. The material in the bin is loaded into the narrow
gauge cars, one carload at a time. When all five cars have been filled, the little
train is pushed into the smelter, bringing the ore to feed the insatiable furnaces.
A little later, the standard-gauge train bestirs itself and meanders off down the
line again.
This completely prototypical scene can be repeated as often as you wish, for whatever
audience is available. If you wish to substitute small, hard candies as loads to
amuse very young spectators, that's probably a good plan.

Ivan Furlanis, who lives in Italy, has expanded
the design of my Dual
Guage Docksider layout to include some additional
narrow-gauge trackage and operations. His HO scale layout is called Hyde Canal,
because somewhere along the way, the "dock" has been hidden!
This is the most complicated of the plans Ivan has drawn (so far) for a layout to
fit in his bookcase. He is showing three dual-gauge turnouts -- one with both gauges
on both legs (three frogs), the other two being right-hand turnouts where the narrow
gauge simply diverges from the standard gauge (only one frog). Gauges involved are
HO standard (16.5mm) and HOe (or HOn30, 9 mm). The German manufacturer Tillig makes
ready-to-run versions of both types of turnouts.
There's plenty of operation in this tiny railroad, on both gauges, fed by the dual-gauge
cassette at the right rear -- where new trains are assembled and filtered into the
operating stream, and other trains can gracefully exit the layout. Both passenger
and freight operations are accommodated on both gauges, and full engine-service facilities
are provided for the litle narrow-gauge steamers that are an important reason for
building this layout!
The setting can be just about anywhere in the world -- North or South America, Britain,
Europe, Japan, Australia -- take your pick. Ivan has been thinking about building
it as a U.S. railroad. Anyone have a prototype suggestion for him?
